Question 3:
A major renovation of an existing K-12 school building would likely use what LEED rating system?
A LEED for Core and Shell
LEED for Core & Shell is a green building rating system for designers, builders, developers and new building
owners who want to address sustainable design for new core and shell construction. Core and shell covers
base building elements such as structure, envelope and the HVAC system. LEED for Core & Shell is
designed to be complementary to the LEED for Commercial Interiors rating system, as both rating systems
establish green building criteria for developers, owners and tenants. (-USGBC)
B LEED for Commercial Interiors
LEED for Commercial Interiors is appropriate for interior spaces that are undergoing alteration work for at
least 60% of the certifying gross floor area. (-USGBC)
C LEED for Schools
LEED for Schools is used for the new construction or major renovation of K-12 projects. This rating system
can also be used for higher-level learning facilities such as colleges and universities.
D LEED for Existing Buildings: Operations and Maintenance
LEED for Existing Buildings is appropriate for existing whole buildings. Typically, these buildings undergo
only improvement work. (-USGBC)
E LEED for New Construction
LEED for New Construction is primarily for whole buildings that are new or undergoing major construction.
This rating system is appropriate for any project that does not have another LEED rating system defined
(Schools, Healthcare, Retail).
Notes:
Reference: USGBC Website
Question 4:
In an existing building, with what can a project team replace CFCs and still earn LEED certification?
A Any non CFC-based refrigerant
Any non CFC-based refrigerant is acceptable to earn LEED certification.
B Natural ventilation
The team can choose to re-design the building to use natural ventilation in place of refrigerants.
C Only natural refrigerants
HCFCs and HFCs can be used as refrigerants as well as natural refrigerants.
D Only HFCs or natural refrigerants
HCFCs and HFCs can be used as refrigerants as well as natural refrigerants.

Notes:
Question 5:
What is an economic benefit of using Regional Materials?
A Encourage responsible forest management
This is an environmental benefit of using certified wood.
B Reduce the use and depletion of finite raw materials
This is an environmental benefit of using rapidly renewable materials.
C Reduce transportation costs
This question asks for an economic benefit. A project that uses Regional Materials will reduce the
transportation costs of delivering the materials to the project site.
D Support the use of local resources
This is a social benefit of using Regional Materials because the community is helped.
Notes:
Question 6:
What should be used during all project phases to verify the green building goals are being met?
A Materials checklist
The materials checklist would be used by contractors to purchase materials needed for the project.
B ID Credit Catalog
The ID Credit Catalog is a list of all ID credits previous projects have awarded.
C LEED Score Card
The LEED Score Card is the quick list of what credits the project team has decided to pursue in the pre-
design phase, based on the project vision and the project's green building goals.
Through each phase this checklist is consulted to ask 'are we on track and are we working towards meeting
those credits we set out to do?'
D Commissioning plan
The commissioning plan is used to verify the installed systems are working as designed.
Notes:

Reference: Sample credit checklist for LEED v3
Question 7:
From where are most local codes adopted?
A International Code Council
Local building codes represent the minimum codes that a project must adhere to.
State and local jurisdictions may develop their own regulations or adopt building codes based on national
model codes. State and local codes are typically based on national model codes published by the
International Code Council (ICC)
B USGBC
USGBC helps set green building standards through LEED, not local codes.
C Federal regulations
D California laws
California laws are usually more stringent than other areas of the country. The laws usually migrate over
time to other parts of the United States.

Question 8:
What accounting methodology is used to evaluate the economic performance of a product or system over its useful
life?
A Life cycle assessment
Life cycle assessment (LCA) is the investigation and valuation of the environmental impacts of a given
product or service. LCA evaluates environmental performance. This view takes into account the whole life of
a product or project (not assessing it from a single point in time).
LCA evaluates a products 'environmental impact'. This differs from life cycle costing evaluates a product's
'economic performance'.
B Cradle-to-cradle
C Life cycle costing
Life cycle costing (LCC) is the evaluation of the total cost of a building or product over its useful life, including
initial, maintenance, repair and replacement costs as well as savings. LCC evaluates economic
performance.
D Triple bottom line accounting

Question 9:
A product's materials were extracted 300 miles from a project site, while the product was manufactured 600 miles
from the project site. What statement is true about the product?
A The product does not count as a regionally harvested and regionally manufactured material
LEED gives credit for regional materials when certain percentages of materials are extracted, harvested or
recovered, and manufactured within 500 miles.
In this example the material was extracted within 500 miles, but it was not manufactured within 500 miles. An
example would be flooring where the trees for the flooring was extracted (cut down) 300 miles from the
project site, but the flooring was milled and finished 600 miles from the project site. Because the flooring was
'manufactured' outside of the 500 mile limit, the material doesn't count as regional.
B The product is considered a regionally harvested and regionally manufactured material
The product is not a regional material because it was manufactured outside of the 500 mile radius LEED
requires for a material to be considered regional.
C The product can count as a salvaged material
Salvaged materials are materials that are being reused. The question states the material is extracted and
manufactured so it is new not salvaged.
D The product counts toward source reduction
Source reduction is a method to reduce construction waste by choosing materials with less packaging or that
are sized correctly.
Notes:
Question 10:
Cabinetry made from walnut shells would help contribute toward earning what LEED credit?
A Building Reuse
Building reuse deals with reusing the floors, roofs, and walls of an existing building.
B Regional Materials
No information was given on the manufacturing distance of the cabinets so this cannot be an answer choice.
C Recycled Materials
Pre-consumer content is content from industry scraps that was diverted from the waste stream and used for
other purposes. Examples include sawdust, wood shavings, wood chips, and print overruns. Excluded are
materials that are re-incorporated into the same manufacturing process that generated it.
Cabinetry made from walnut shells is an example of a pre-consumer recycled material.
D Construction Waste Management
Cabinets are usually built to order and have minimal waste generated during installation. Any waste
disposed of would contribute to construction waste management but not enough information is given in the

question to make this a valid choice.
Notes:
Reference: n/a
Question 11:
How does drip irrigation save water?
A By using only non-potable water
B By reducing the heat island effect
C By reducing the microclimate factor
D By increasing irrigation efficiency
Water efficient landscaping helps reduce the need from potable water from local and regional aquifers. Drip
irrigation is a highly effective way to deliver water to a plant's roots because the water isn't lost to the wind,
evaporation, or runoff.
Drip irrigation has a 90% irrigation efficiency compared to 65% for conventional sprinkler systems.
Question 12:
Which of the following is not an alternative LEED recommends for reducing stratospheric ozone depletion?
A Using natural refrigerants
Natural refrigerants are benign to the atmosphere.
B Designing a building to use natural ventilation
Natural ventilation does not require the use of refrigerants and would result in no refrigerants gassing into
the ozone layer.
C Selecting refrigerants that have a long atmospheric lifetimes
Refrigerants that are in the atmosphere longer would have a longer (greater) impact on the ozone layer.
D Selecting refrigerants with lower ODP and GWP
Refrigerants with lower ODP and GWP have a lesser effect on the ozone layer.
Notes:
Question 13:
Which of the following are frequently considered types of blackwater?

A Dishwasher water
Treatment and definitions of blackwater vary - in some jurisdictions, blackwater is wastewater generated
from toilet flushing; in others, it includes water from kitchen sinks or laundry facilities. It is distinct from
greywater or sullage, the residues of washing processes. Check with local codes for the area's definition of
blackwater.
B Water from kitchen sinks
Water from kitchen sinks is often defined as blackwater.
C Municipally reclaimed water
This is a type of recycled water that can be used for flushing or irrigation (not drinking).
D Process water for cooling towers
Process water is not blackwater.
Notes:

Question 14:
What impacts a project's ability to achieve Development Density?
A Locating the project near 2 or more bus stops
Locating a project near public transportation can help earn Alternative Transportation, Public Transportation
Access.
B Measuring an accurate project boundary
The Development Density credit uses the density of the area of the project being built. This density is
compared to the densities of other projects within a calculated density radius.
An accurate project boundary is used to determine the project's density.
C Making sure the project has pedestrian access to at least 10 basic services within 1/2 mile
Locating the project within 1/2 mile of 10 basic services helps the project earn Community Connectivity.
D Building on a brownfield site in a dense urban area
This would help a project earn Brownfield Redevelopment.
Notes:
Question 15:
What landscaping strategy will best eliminate the need for irrigation?

A Micro-irrigation
Micro-irrigation and drip irrigation are both irrigation techniques.
B Drip irrigation
Micro-irrigation and drip irrigation are both irrigation techniques.
C Xeriscaping
Xeriscaping is a landscaping method that employs drought-resistant plants to minimize or eliminate water
use.
D Mulching
Mulching helps retain moisture for plants, but it is not the BEST strategy from the choices given.
Question 16:
What does LEED accept as part of a building design to qualify as open space for projects in urban areas?
A Vegetated (green) roofs
A vegetated roof may count as open space for projects in urban areas.
B Balconies
Balconies are not considered open space.
C Higher density buildings
Higher density buildings do not contribute to open space requirements.
D Shaded parking lots
Shaded parking lots are not considered open space.
Notes:
Question 17:
A potential LEED project could be certified under either LEED for Existing Buildings or LEED for New Construction.
How should the project team decide which rating system to use?
A The project team must independently decide which rating system to use
The 40/60 rule is provided for guidance. Ultimately the project team decides.
B The rating system that could earn the most points should always be selected
USGBC/GBCI does not require selecting the rating system that would earn the most points.

C Use the 40/60 rule
LEED has a 40/60 rule to help project teams decide on a rating system:
 If a particular rating system is appropriate for 40% or less of a LEED project building or space, then
that rating system should not be used.
 If a particular rating system is appropriate for 60% or more of a LEED project building or space,
then that rating system should be used.
 Project teams with buildings and spaces that do not fall into the scenarios described in a) and b)
must independently assess their situation and decide which rating system is most applicable.
D LEED for New Construction always has priority since it is the most popular rating system
While LEED for New Construction is the most popular rating system used, it is not given a priority by
USGBC.
Notes:
Reference: LEED Rating System Selection Policy
Question 18:
What must occur if a project includes a CFC phase-out plan?
A The project must implement green house gas emissions reporting
LEED does not require greenhouse gas emission reporting or tracking.
B The CFC-based refrigerants must be replaced with HCFCs
The CFC-based refrigerants do not have to be replaced with HCFCs - they can be replaced with other
refrigerants.
Be careful of the wording of questions that use absolute terms such as must, not, always, etc.
C The annual leakage of CFC-based refrigerants must be reduced to 5% or less
D The CFC-based refrigerants must be replaced with low ODP refrigerants
The CFC-based refrigerants do not have to be replaced low ODP refrigerants - they can be replaced with
other refrigerants.
Be careful of the wording of questions that use absolute terms such as must, not, always, etc.
Notes:
The project team can take 5 years from project completion to phase out CFC-based refrigerants, as long as the
annual leakage rate of CFC-based refrigerants is reduced to 5% or less.
Projects that have a shown a simple-payback of CFC based refrigerant systems will take more than 10 years can be
exempt from this requirement, but must still reduce the annual leakage rate to 5% or less.
Simple payback takes the cost of an item or strategy and divides that number by the yearly savings that product or
strategy creates. If replacing a CFC-based system costs $150,000 but saves a property manager $50,000 a year, the
project will have a simple payback period of 3 years.

Question 19:
A project team for a LEED for New Construction project has decided to implement a community recycling program
that will allow community residents to drop off computers and electronics at the project site. What LEED category
could the project earn points under?
A Sustainable Sites
B Materials and Resources
The prerequisite for projects to have an on-site recycle program found in the Materials and Resources
category requires recycling of the following for the building occupants, not the general community.
 paper
 cardboard
 glass
 plastics
 metals
C Energy and Atmosphere
D Indoor Environmental Quality
E Innovation in Design
This is an example of innovative performance, because the project is creating a quantifiable program that
provides an environmental benefit to the community.
Also, only allowing the community to recycle computers and electronics doesn't make the program non-
comprehensive.
Notes:
Reference: Guidance on Innovation & Design (ID) Credits
Question 20:
Locating a project near mass transit would have what economic benefit?
A Transportation costs for material delivery would be reduced
Mass transit isn't used to deliver project materials to a site.
B Habitat and natural resources would be preserved
Protecting habitat and natural resources is one of the environmental goals of community connectivity
C Greenfields would be protected
Protecting greenfields is one of the environmental goals of community connectivity.
D Parking capacity can be reduced
The parking capacity can be reduced which would reduce the amount of money spent on the parking

structure or area.
Notes:
Question 21:
What defines the open space of a site area if there is no local zoning?
A Constructed area of the project boundary
B Unconstructed area of the project boundary
C Property area minus the development footprint
For the purposes of LEED, open space is the property area minus the development footprint, when local
zoning does not define open space.
Open space must be vegetated and pervious.
D Total area within the project boundary of the applicant building
Notes:
Question 22:
Biomass is what type of material?
A Fly-ash
B Landfill gas
C Animal waste
D Plant material
Biomass is plant material converted to heat energy to produce electricity.
Notes:
Question 23:
Who can use the USGBC logo?
A Any USGBC member

USGBC members must use the USGBC member logo.
B Any LEED AP
LEED APs do not use the USGBC logo to designate they are a LEED AP.
C Any USGBC member or USGBC chapter
USGBC chapters use the USGBC chapter logo.
D Only organizations that have received approval by the USGBC marketing department
Use of the USGBC logo is granted through their marketing department.
This question pertains to exam objective I.P USGBC Policies (e.g., trademark usage; logo usage) from the
LEED GA Candidate Handbook. While we receive many comments about the relevance of these types of
questions, the subject matter may come up on your exam.
The use of the USGBC and LEED logos are listed in the exam objectives to prevent misuse of these logos
and to purposely or inadvertently spread incorrect information about LEED and USGBC. It is important to
know how you can and cannot use the logo so that you help the green building movement rather than hinder
it.
The USGBC logo cannot be used to link to third-party websites or for product certification.
The USGBC Member logo is used to denote USGBC membership, not the USGBC logo. The USGBC logo
cannot be used to indicate membership - the USGBC member logo is required to be used. There is both a
USGBC logo and a USGBC member logo, both of which have differing uses and requirements.
Notes:
Reference: USGBC website
Question 24:
The baseline water use of a lavatory faucet is:
A 1.0 gpf
B 2.2 gpf
C 2.2 gpm
2.2 gallons per minute (gpm) per the EPAct of 1992.
D 1.0 gpm
Notes:
Question 25:
What would installing a green roof help with?
A Increasing off-site renewable energy
A green roof does not impact offsite renewable energy.

B Reducing heat islands
C Increasing the lifespan of the roof
Green roofs typically have a longer life-cycle than traditional roofs (according to LEED).
D Eliminating CFCs
The choice of refrigerant and if natural or mechanical ventilation is used are decisions that help eliminate
CFCs.
Notes:
Green roofs help reduce heat islands. They also help provide greater insulation of the roof to reduce energy
consumption.
The heat island effect is created when developed areas have higher temperatures than surrounding rural areas. An
urban heat island effect is caused by sunlight heating up dark colored surfaces such as roads and rooftops. Huge
quantities of heat are generated in buildings that have dark rooftops and absorb heat rather than reflect it.
Question 26:
What is a drawback of using a biofuel-based energy system?
A These systems are not acceptable for LEED credits
B Production is unreliable or inconsistent
C The lack of regulatory oversight
D Fossil fuels must still be used to produce biofuels
Biofuel based technologies use a renewable/recurring supply of organic material such as plant matter
(biomass) to produce electricity. Bio-fuels are fuels derived from biomass. Bio-fuel systems reduce
dependence on fossil fuels.
For LEED biofuels include:
 untreated wood waste
 agricultural crops or waste
 animal waste
 other organic waste
 landfill gas
An issue with bioenergy is the amount of fossil fuel energy used to produce it. Bioenergy such as the burning
of ethanol from corn, requires energy to produce the fuel.
Notes:

Question 27:
What will help with reducing stormwater runoff and reducing the heat island effect?
A Installing a bioretention pond
A bioretention pond would only reduce stormwater runoff. LEED awards projects for reducing the heat island
effect by shading pervious surfaces, installing open grid paving, and using reflective materials. Installing a
retention pond does not do that.
B Harvesting rainwater
Harvesting rainwater would only reduce stormwater runoff.
C Installing pervious pavement that has high SRI values
Pervious pavement allows stormwater to percolate through to the ground, reducing runoff. Pavement that is
reflective reduces the heat island effect.
D Maximizing the floor-area ratio
This would increase the density of the building.
Question 28:
Which of these sites if selected would most help with community connectivity?
A A site that has underground parking and open space on the property
Open space on the site does not count as community connectivity.
B A site located within 1/2 mile walking distance of a commuter rail line
This would help with providing public transportation access.
C A site within 1/2 mile walking distance to a public park
Community connectivity is the quantity of connection between a site and the surrounding community.
Community connectivity channels development to urban areas with existing infrastructure. This includes
areas with walkways and areas near basic services.
Basic services are those services that are open to the public, and are common services that people might
use regularly. People must be able to walk between the project and the service without being blocked by
walls, highways, or other barriers (this is called pedestrian access). LEED encourages building near a variety
of basic services, not just one type of service such as twelve clothing stores in a strip mall. LEED provides
examples of basic services as:
Bank
Church
Supermarket / convenience store
Day care
Dry cleaner / laundry mat
Fire station
Salon
Hardware store

Library
Medical / dental office
Park
Pharmacy
Post office
Restaurant
School
Theatre / museum
Community center
Gym
D A site located next door to residential condominiums
Residences are not a type of basic service.
Notes:
Question 29:
What does the use of light-colored, pervious paving help with?
A Regional materials
B Heat island effect
Light colored paving, or paving with a high SRI value, helps reduce the heat island effect.
The heat island effect is created when developed areas have higher temperatures than surrounding rural
areas. An urban heat island effect is caused by sunlight heating up dark colored surfaces such as roads and
rooftops. Huge quantities of heat are generated in buildings that have dark rooftops and absorb heat rather
than reflect it.
C Stormwater management
Pervious paving helps with reducing stormwater runoff by allowing stormwater to percolate through the
pavement.
D Recycling
Notes:
Question 30:
What best defines durability?
A The practice of managing resources to meet the long-term product needs of humans
This is good environmental stewardship.
B The design choice that has the least environmental impact while considering the triple-bottom-line

An integrated process is used to design the greenest building possible while considering the triple-bottom-
line.
C Materials that reduce operating costs and maintenance expenses over the product's lifetime
Using materials with lower life cycle costs helps reduce operating costs and maintenance expenses over the
products lifetime.
D The ability of a building or any of its components to perform its required function in its service environment
over the period of time without unforeseen cost for maintenance or repair
This defines durability.
Notes:
Reference: LEED for Homes Rating System
Question 31
What is a financial benefit of implementing an occupant recycling program?
A Reduced landfill fees
B Reduced extraction of virgin materials
C Minimized air pollution
D Reduced energy use
Notes:
Recycling can result in reduced landfill and tipping fees since the materials are diverted from landfills. Sometimes the
recycled materials can be sold to waste haulers, creating a net gain.
Question 32:
What is the primary purpose of registering a project for LEED?
A To get media publicity for your company and the project
While this is a secondary benefit it is not the primary purpose.
B To register individuals for the GBCI exams
Project registration is unrelated to exam registration.
C To gain access to project tools and resources
The primary purpose for registering a project is to gain access to the project tools needed for the certification
process.
D To obtain free USGBC consulting

USGBC consulting is not free.
Notes:
Reference: GBCI website for registration
Question 33:
Average housing density is defined as:
A Housing Units / 120,000 sq. ft.
B Square Footage of Housing Units / 120,000 sq. ft.
C Housing Units / Acres of Buildable Land
The LEED definition of average housing density is defined as Housing Units / Acres of Buildable Land.
D Square Footage of Housing Units / Acres of Buildable Land
Notes:
Reference: LEED for Homes Rating System
Question 34:
The definition of which of the following terms varies by state and local code?
A Heat island
B Climate change
C Graywater
Graywater is defined by the Uniform Plumbing Code (UPC) as untreated house-hold wastewater which has
not come into contact with toilet waste or kitchen sinks.
Some states and local codes have other definitions.
Graywater is an important part of the LEED process, and knowing how it is defined by state/local code is a
critical first step in pre-design, if graywater is a consideration for the project. The intent is to learn that what
graywater is varies from place to place.
D Greenfield
Notes:
Question 35:
Green building solutions should include a balance:

A Among a limited number of stakeholders
The balance should be between all stakeholders rather than a limited number of stakeholders.
B Between urban and suburban areas
This is not correct.
C Between energy use and energy creation
Not all green buildings are going to create energy (on-site renewables).
D Among environmental, social, and economic benefits
This is the triple bottom line. In practical terms, triple bottom line accounting means expanding the traditional
reporting framework to take into account environmental and social performance in addition to financial
performance.
You might hear the triple bottom line referred to in different ways:
Economic growth, ecological balance, and social progress: The World Business Council for Sustainable
Development
Economic viability, environmental stewardship, social awareness: USGBC
Notes:
Reference: GBES LEED Green Associate Study Guide
Question 36:
Which of the following do not contribute to increasing the heat island effect in urban areas?
A Open grid pavement
Open grid pavement is a strategy LEED accepts to reduce heat islands. Open grid pavement has cells in it
to allow vegetation to grow.
B Vehicle exhaust
Other causes of the heat island effect include air-conditioners, vehicle exhaust, and calm and sunny
weather.
Reduced air flow between buildings and narrow streets increases the effect.
C Bioretention ponds
Bio-retention ponds are landscape features that help control rainwater runoff. They are commonly called rain
gardens.
LEED does not consider any type of water body or landscape feature as something that contributes to the
heat island effect.
D Absorption of heat by hardscapes and its radiation to surrounding areas
The primary cause of the heat island effect is dark surfaces such as rooftops or dark asphalt pavement that
absorb heat and radiate it into the surrounding areas.

Notes:
Reference: n/a
Question 37:
What are MERV ratings used for?
A Measuring the effectiveness of a sustainable purchasing policy
B Comparing the efficiency of air filters
MERV or Minimum Efficiency Reporting Value is a standard comparison of the efficiency of an air filter. The
MERV scale ranges from 1 (least efficient) to 16 (most efficient), and measures a filter's ability remove
particles from 3 to 10 microns in size.
The higher the rating the better the air quality.
C Comparing the VOC content of paints and sealers
D Determining the quantity of recycled content in a material
Notes:
Question 38:
A project team decides to build up, instead of out, resulting in an increase in the floor area ratio of an office building.
What credit might this help earn if the additional land area is turned into a dry pond?
A Brownfield Redevelopment
B Water Efficient Landscaping
C Development Density
Development density is the total square footage of buildings in a particular area divided by acre amount of
the same area, expressed as SF/Acre. For example 20,000 SF per acre.
D Stormwater Design
If the floor area ratio is increasing by building up instead of out that means the building footprint is
decreasing. A smaller building footprint will mean there is more open space available (assuming it doesn't
get paved).
A dry pond (detention pond) is used to store excess stormwater. Dry ponds are basins whose outlets have
been designed to detain stormwater runoff for some minimum time (e.g., 24 hours). The stormwater will
slowly seep into the ground or discharge as determined by the pond design to allow pollutants to settle.
Unlike wet ponds, these facilities do not have a large permanent pool of water.

Notes:
Question 39:
What is the best type of site to develop on?
A Nature preserve
B Greenfield
C Wetland
D Previously developed site
Selecting a previously developed site avoids disturbing natural areas that have not been developed.
Question 40:
LEED requires which of the following to be done in order for a project to earn certification?
A Include a LEED AP on the project
No LEED AP is required for project certification.
B Achieve all prerequisites for the rating system
ALL prerequisites must be met for the rating system. If even a single prerequisite cannot be achieved in the
rating system being certified under the project cannot earn LEED certification.
C Have the project administrator be a LEED AP
The project administrator does not have to be a LEED AP.
D Meet the Minimum Program Requirements
All Minimum Program Requirements must be met.
E Achieve at least 50 points
Projects must achieve at least 40 points (not 50 points) to become LEED Certified.
Notes:
Reference: n/a
Question 41:
What process uses heat recovery to capture heat from the process of generating electricity and then turns the
recovered heat into thermal energy that can be used to heat a building?

A Tertiary treatment
A project that treats 50% of wastewater onsite to tertiary standards can earn the Innovative Wastewater
Technologies credit. Tertiary treatment of wastewater leaves the water in a state where it can be used for
agriculture or discharged back into the environment. It is not suitable for drinking.
B Cogeneration
Combined heat and power (CHP) is an electricity generation technology, also known as cogeneration, that
recovers waste heat from the electric generation process to produce simultaneously other forms of useful
energy, such as usable heat or steam. On average, two-thirds of the input energy used to make electricity is
lost as waste heat. In contrast, CHP systems are capable of converting more than 70 percent of the fuel into
usable energy. (Guide to Purchasing Green Power)
C Evopotranspiration
Evopotranspiration is water leaving plants and soil and returning back to the atmosphere.
D Commissioning
Commissioning is systematic process of assuring that a building performs in accordance with the design
intent and the owner's operational needs.
Notes:
Reference: Guide to Purchasing Green Power
Question 42:
What item would NOT be included in commingled recycling?
A Food waste
At a minimum, a recycling program should include paper, cardboard, glass, plastic, and metal.
Stones, dirt, hazardous materials, batteries, mercury-containing light bulbs, and food waste would not be
included.
B Glass
C Cardboard
D Metal
Notes:
Question 43:
Developing in areas near transportation, housing, and jobs in order to leave open spaces and farmland free from
development is called:
A Infill development

B Location and linkage
C Neighborhood pattern and design
D Smart growth
While the other choices can contribute to smart growth, the correct choice is the term used for the question's
definition.
Question 44:
What can be used to compare the energy performance of two buildings?
A LEED
LEED itself does not compare energy use to buildings. LEED references other standards that are used to
improve energy performance. LEED compares the greenness of two buildings, which includes much more
than just the energy performance.
B LEED Online
LEED Online is a tool used to manage the documentation of a LEED project.
C ENERGY STAR
ENERGY STAR is specific to energy performance and can be used to compare building performance.
D Green-e
Green-e is a program established to promote green electricity products and provide consumers with a
nationally recognized method to identify those products.
Question 45:
What standards would be used for the Energy and Atmosphere category?
A ASHRAE 90.1-2007
ASHRAE 90.1-2007 establishes minimum requirements for the energy efficient design of buildings (not
included are single family homes or multifamily homes less than 3 stories).
B ASHRAE 62.1-2007
ASHRAE 62.1-2007 Ventilation for Acceptable Indoor Air Quality specifies minimum ventilation rates. These
rates are used to improve indoor air quality as part of the IEQ credit category.
C ASHRAE 55-2004
ASHRAE 55-2004 Thermal Environmental Conditions for Human Occupancy help with defining what makes
a comfortable indoor environment for occupants. Indoor conditions are considered acceptable if 80% or
more of occupants find them acceptable. This standard is used in the IEQ category.

D EPAct 1992
EPAct 1992 is used for calculating the baseline water use of a project in the Water Efficiency category.
Notes:
Question 46:
A project team discovers a new way to avoid the heat island effect. How does the LEED certification process reward
this new concept?
A An extra Heat Island Effect point would be awarded
B Heat Island Effect is covered by LEED, so no additional points would be awarded
Innovative performance as part of the Innovation in Design or Operations category is meant for green
building categories not specifically addressed by LEED. Innovation credits are not awarded for the use of a
particular product or design strategy if the technology aids in the achievement of an existing LEED credit.
USGBC/GBCI uses the CIR process for cases like this. A CIR could be submitted that specifies an alternate
way to earn the Heat Island credit. However only the Heat Island credit would be earned, not an ID point or
extra points.
C An exemplary performance point would be awarded
D An innovative performance point would be awarded
Question 47:
What are the environmental benefits of using salvaged wood flooring in a residential project?
A The wood flooring will reduce the demand for virgin resources
Salvaged materials reduce the demand for virgin materials and reduce waste. Flooring that is taken from a
demo project can be reused elsewhere so that trees do not have to be cut down to supply wood for new
flooring.
B The wood flooring will have a lower installation cost
The installation cost is an economic issue, not an environmental issue.
C The wood flooring will have a lower cost since it did not have to be extracted from a forest
A lower cost would be an economic benefit. Most salvaged flooring would have a higher cost since they tend
to be of higher quality wood.
D The wood flooring will increase the tax base of the local economy
There is a benefit to society (remember the triple bottom line?) assuming the material was salvaged locally
and re-used locally.

Notes:
Question 48:
Which of the following is not a credit category for LEED for Neighborhood Development?
A Awareness and Education
This is a LEED for Homes specific credit category.
In the commercial building rating systems the topics of Awareness and Education are covered under the
Innovation and Design / Innovation in Operations category.
B Neighborhood Pattern and Design
C Smart Location and Linkage
D Green Infrastructure and Buildings
Question 49:
A vehicle meeting which standard would be considered low-emitting and fuel efficient?
A SCAQMD air quality standards
SCAQMD is an air pollution control agency.
B Green-e Certified
Green-e is a program established to promote green electricity products and provide consumers with a
nationally recognized method to identify those products.
C Zero Emission Vehicle (ZEV) by the California Air Resources Board
Vehicles must be classified as a Zero Emission Vehicle (ZEV) by the California Air Resources Board or have
a green score of 40 or more from the ACEEE annual vehicle rating guide.
The LEED Credit is named Low-Emitting and Fuel-Efficient Vehicles and ZEVs qualify under that credit. The
question doesn't ask about Zero-Emitting and Fuel-Efficient Vehicles because there is no LEED credit by
that name.
D EPA Transportation and Air Quality standard
Notes:

Question 50:
Each LEED credit and prerequisite includes the intent of the credit/prerequisite. What is the 'intent' of a
credit/prerequisite?
A Addresses the synergies and trade-offs between credits
This information is covered in the related credits section of the reference guide.
B Details the level of performance needed to achieve a credit
This is what requirements contain, or exemplary performance.
C Identifies the main sustainability goal or benefit of the prerequisite or credit
This is USGBC's definition of a LEED intent.
D Outlines concerns specific to specific regions
This is what regional variations contain.
Notes:
Question 51:
What is purchasing products with less packaging an example of?
A Construction waste management
Construction waste management is the process of diverting waste from landfills and incinerators.
B Waste diversion
Waste diversion is the act of keeping waste from a landfill either by donating materials, recycling them, or
reusing them.
C Commingled recycling
Commingled recycling, or using one container to collect and recycle several materials, is a method for
reducing the quantity of waste sent to landfills.
D Source reduction
Source reduction is the EPA's top-ranked strategy for reducing waste. Source reduction chooses products
with less packaging and material, which have a greater environmental impact throughout the product's life
cycle.
Notes:

Question 52:
Approximately 50% of chillers in existing buildings use what refrigerant?
A HFC-23
B NH3
C CFC-11
CFC-11 is used in chillers for about 50% of existing buildings. Nowadays it is encouraged to replace these
systems with newer and more efficient systems that use more environmentally friendly refrigerants. Doing so
would save money in the long term.
D HCFC-22
Notes:
A centrifugal chiller is one of the most economical means to cool large buildings. These units use water and a
refrigeration cycle to provide cooling.
Question 53:
Which of the following includes standards for accessible design?
A ASHRAE
B Americans with Disabilities Act
C Fair Housing Amendments Act
D Section 504 of the Rehabilitation Act
Notes:
The Americans with Disabilities Act includes accessibility guidelines.
Question 54:
Who decides if wastewater from showers can be used for irrigation?
A Universal plumbing code
B Local authorities with jurisdiction in the area
Blackwater does not have a single definition accepted nationwide. Adjacent cities may have different codes
that allow or prohibit the use of sink/shower water for non-potable uses. On jurisdiction may define
sink/shower water as blackwater and not permit its use, while another may define it as graywater and will

permit its use. Review local codes before making design decisions based on the use of wastewater.
C Project team
D USGBC via the CIR process
Notes:
Question 55:
What must a project do to earn LEED certification after selecting a rating system?
A Pay the relevant fees and have a Green Rater approve the project
Green Raters are only relevant to the LEED for Homes rating system.
B Satisfy relevant prerequisites for the selected rating system and earn a minimum number of points
'Satisfy relevant prerequisites' is not correct because project teams can't choose what prerequisites to meet
for a given rating system. All prerequisites for the rating system the project will certify under must be
followed.
At least 40 points must be earned for a building to be LEED Certified at the base level (Certified).
Certified 40-49 points
Silver 50-59 points
Gold 60-79 points
Platinum 80+ points
C Earn a minimum number of points only
Prerequisites must also be met.
D Satisfy all prerequisites for the selected rating system and earn a minimum number of points
After selecting a rating system a project must satisfy all prerequisites and earn a minimum number of points
to be certified.
Notes:
Reference: GBCI LEED Certification Policy Manual
Question 56:
What statement is true regarding wool carpet made from wool leftover from the carpet manufacturing process?
A This material does not contain recycled content
This example would not be considered any type of recycled material. If a manufacturing process uses scraps
and puts them back in the assembly line, it is a good practice but it does not count towards pre or post
consumer recycled content.
B This material is an example of post-industrial recycled content

Post-industrial content is now called pre-consumer content.
C This material is an example of post-consumer recycled content
Post-consumer material - recycled material generated from the waste of household, commercial, industrial,
or institutional end-users
Postconsumer recycled content - is the percentage of material in a product that was consumer waste. The
recycled material was generated by household, commercial, industrial, or institutional end-users and can no
longer be used for its intended purpose. It includes returns of materials from the distribution chain. Examples
include construction and demolition debris, materials collected through recycling programs, discarded
products (e.g., furniture, cabinetry, decking), and landscaping waste (e.g., leaves, grass clippings, tree
trimmings). (ISO 14021)
D This material is an example of pre-consumer recycled content
Pre-consumer content - formerly known as post-industrial content, is the percentage of material in a product
that is recycled from manufacturing waste. Examples include planer shavings, plytrim, sawdust, chips,
bagasse, sunflower seed hulls, walnut shells, culls, trimmed materials, print overruns, overissue publications,
and obsolete inventories. Excluded are materials such as rework, regrind, or scrap generated in a process
and capable of being reclaimed within the same process that generated it (ISO 14021).
Notes:
Question 57:
Building permit fees for a project are what type of cost?
A Soft cost
A soft construction cost is one that is not directly related to building, construction, etc. These include building
permit fees, architect fees, legal, financing, engineering fees, commissioning, and other costs incurred
before and after construction.
B Hard cost
Hard costs: By far the largest portion of the expenses in a construction budget, the hard costs are mostly
comprised of the actual construction costs incurred to build the project.
Examples include masonry, wood, steel, carpet, tile, mechanical systems, roofing.
C Life cycle cost
performance.
D Operating cost
Operating costs are another type of cost for a building in addition to hard and soft costs. These costs occur
after the building is complete and up and running. These costs include utilities such as water and electricity
as well as the costs of maintenance personnel - janitorial, landscape, security.

Notes:
Reference: n/a
Question 58:
What should be done to minimize a building's impact on ozone depletion?
A Zero use of CFCs
The rating systems have a prerequisite for Fundamental Refrigerant Management which requires zero use of
CFCs. CFCs are known to cause ozone depletion.
For buildings with existing systems that use CFC-based refrigerants, the systems must be phased out within
5 years after the project is completed, unless a third-party audit shows the simple payback for
retrofitting/replacement is more than 10 years.
Fundamental Refrigerant Management differs from Enhanced Refrigerant Management which requires either
using no refrigerants or using refrigerants that are low in Ozone Depletion Potential and Global Warming
Potential (ODP and GWP).
B Use halons in fire suppression systems
Halons cause ozone depletion.
C Reduce heat islands
Heat islands do not cause ozone depletion.
D Install a green roof
Install a green roof helps reduce heat islands, and can reduce the amount of energy a building uses due to
the insulating properties of the roof.
Notes:
Question 59:
Untreated stormwater can NOT be used for what purpose?
A Landscaping fountains
This is permitted if local code allows it.
B Drip irrigation
This is permitted if local code allows it.
C Washing dishes
Stormwater would need to be treated before it can be used in a dishwasher.
D Makeup water
Makeup water is water used to replace water in cooling towers.

Question 60:
What types of old materials/items does LEED NOT suggest reusing on a project?
A Asphalt
Asphalt can be reused as an aggregate.
B Furniture
LEED rewards projects for reusing materials such as furniture.
C Showerheads
D Flooring
LEED rewards projects for reusing materials such as flooring.
Notes:
Old plumbing fixtures are frequently more inefficient than newer models and consume more water. For new
construction or renovations, consider higher efficiency models, such as waterless urinals.
Question 61:
LEED Minimum Project Requirements prohibit gerrymandering. What does this mean?
A Making the project building area less than 2% of the site area
B Defining the site area to exclude green space between campus projects
C Hiding project costs in ROI calculations
D Adjusting a project boundary for the benefit of earning credits/prerequisites
Gerrymandering is prohibit: 'The boundary may not unreasonably exclude sections of land to create
boundaries in unreasonable shapes for the sole purpose of complying with prerequisites or credits'.
Notes:
Reference: Minimum Program Requirements
Question 62:
___________ of a LEED project must be certified under a single rating system.
A 100%

100% is not correct because the statement would read '100% of a LEED project must be certified under a
single rating system' which is not true. Only the gross floor area 'must be'.
B The gross floor area
The gross floor area of a LEED project must be certified under a single rating system. Projects can't exclude
some of the floor area of the project in order to achieve credits more easily.
C The entire property boundary
D At least 25%
Notes:
Question 63:
What strategies will not reduce the use of potable water for irrigation?
A Using graywater for irrigation
Graywater can be used in some jurisdictions for non-potable uses such as irrigation.
Graywater is defined by the Uniform Plumbing Code (UPS) as untreated house-hold wastewater which has
not come into contact with toilet waste or kitchen sinks.
Graywater includes used water from bathtubs, showers, bathroom wash basins, and water from clothes-
washer and laundry tubs. It does not include water from kitchen sinks or dishwashers.
B Installing native plants
Native plants require less irrigation, less fertilizer, and less maintenance than non-native plants. Native
plants thus reduce the need for potable water use for landscaping, and reducing water use for landscaping in
general. Native plants can be used to restore previously developed sites to increase open space.
C Using stormwater for irrigation
Stormwater can be collected and used for irrigation if local codes allow it.
D Replacing permeable pavement with turf grass
The installation of turf grass will increase the watering needs of the landscape.
Notes:
Reference: n/a
Question 64:
What should potable water be used for?
A Drinking
B Flushing toilets

LEED rewards projects for using non-potable water for flushing toilets.
C Irrigation
LEED rewards projects for using non-potable water for irrigation.
D Cooling towers
LEED rewards projects for using non-potable water for cooling towers.
Notes:
Potable water meets or exceeds EPA's drinking water standards. Potable water can be used for any purpose, though
the intent of the water efficiency credits is to reduce the use of potable water.
Question 65:
The baseline water demand within a building includes the measurements of which of the following items?
A Irrigation systems
The water use from irrigation is not included in the baseline water demand of a building.
B Toilets
C Bathroom faucets
D Cooling towers
The water use of cooling towers is not included in the baseline water demand of a building.
E Urinals
Notes:
The baseline water demand within a building includes the measurement of fixtures and fittings (toilets, faucets).
Toilets are measured in gallons per flush, while fixtures are measured in gallons per minute.
Question 66:
How many points would a project earn for having 3 LEED APs as principal participants on a project?
A 0
B 2
C 3
D 1

No matter how many LEED APs are working on a project, there is still only one point available for this credit.
For example if a project had 100 LEED APs working on a project as principal participants, the project would
not earn 100 points and get a Platinum certification.
Notes:
Question 67:
LEED credit forms must be signed by which person?
A Project owner
B Local code official
C Declarant
A declarant is 'A LEED project team member who is technically qualified to verify the content of a LEED
credit submittal template, and is authorized by the project administrator to sign the template and upload it to
LEED Online. The Declarant must have had a significant degree of responsibility for the credit, i.e.,
participation with and/or oversight of either implementing the credit in the project building or of verifying its
outcome.' (USGBC)
The declarant is the person who will sign a submittal template. Each template can have a different declarant.
Each rating system will have its own set of forms that must be completed and submitted for documentation
and verification. These forms are called submittals or credit templates, and are accessed with LEED Online.
The project administrator assigns credits/prerequisites to individuals (declarants) to complete.
D Project manager
Question 68:
Each commercial (non-homes) rating system is comprised of what elements?
A CIRs
B Credits
C Minimum Program Requirements
D Strategies
E Prerequisites
Notes:
Reference: GBCI LEED Certification Policy Manual
Each commercial (non-homes) rating system is comprised of a series of the following elements:
1. Minimum Program Requirements

2. Prerequisites
3. Credits
Question 69:
Which of the following has the greatest direct impact on global warming?
A SRI of a building's roof
This is an indirect impact because the roof does not contribute to global warming. The roof has an indirect
impact by either requiring more/less fossil fuels to be burned to heat/cool the building.
B Use of natural refrigerants
Natural refrigerants (Carbon dioxide, ammonia, propane) have no ozone depletion potential. Since these
refrigerants are much less efficient than HCFCs or HFCs, more energy is needed to get the same
refrigeration levels.
Equipment that burns more energy for cooling as a result of lower efficiency or the use of natural refrigerants
can result in greater global warming. While natural refrigerants do not directly impact global warming, they
indirectly impact global warming by requiring more energy to achieve lower refrigeration temperatures.
C Chillers' operating efficiency
How efficiently HVAC equipment is directly impacts how much fossil fuel is burned to heat and cool a
building.
D Building orientation
Building orientation has an indirect impact since the building's orientation does not itself increase global
warming. The orientation has an indirect impact by either requiring more/less fossil fuels to be burned to
heat/cool the building.
Notes:
Question 70:
How can a LEED project earn credit for Green Power?
A By installing solar panels
Installing solar panels helps with On-site Renewable Energy.
B By selecting a Green-e certified power provider
For states with open electricity markets a Green-e certified power provider can be selected. Off-site
renewable energy is accepted by LEED towards the Green Power credit.
C By purchasing any renewable energy source
Only energy sources certified by Green-e are acceptable.
D By purchasing biofuel based power

Purchasing biofuel based power can help but only if the energy source is Green-e certified.
Notes:
Question 71:
What does a project team have the ability to do only after a project is registered?
A Submit a Credit Interpretation Request (CIR)
CIRs can only be submitted for registered projects through LEED Online.
B Create a GBCI website account

Question 72:
What does 'LEED Certified' indicate?
A A project that has been certified
B The LEED certification process
C The LEED Rating System
D A project that has been certified at the base level
This question is explicitly addressed in the USGBC Trademark Policy on page 16.
'LEED certification' with lowercase 'c' is used to describe the certification process. 'LEED certified' with
lowercase 'c' is used to describe a project that has been certified. 'LEED Certified' with capital 'C' is used to
describe a project that has been certified to the base level: Certified.
The certification levels are:
Certified
Silver
Gold
Platinum

A building can be 'certified' without being 'Certified', but in that case it would have received
Silver/Gold/Platinum certification.
Notes:
Reference: USGBC Trademark Policy
This question pertains to exam objective I.P USGBC Policies (e.g., trademark usage; logo usage) from the LEED
Green Associate Candidate Handbook.
While we receive many negative comments about the relevance of these types of questions the subject
matter may come up on your exam. You are better off seeing questions from every exam objective than being
under-prepared because some questions covering the GBCI exam objectives you will be tested on seem
silly.
Question 73:
Placing a project's parking underground would help with what LEED credit?
A Heat island effect
Moving parking spaces underground reduces the quantity of hardscapes above ground. Less hardscapes
result in lessening the heat island effect.
B Preferred parking
Preferred parking is not itself a LEED credit. Preferred parking is a requirement for some credits.
C Parking capacity
Moving parking underground doesn't change the capacity.
D Recycled materials
Recycled materials and parking location are not related.
Notes:
Question 74:
What urban area is a best choice for a LEED project?
A Areas with zero development density
Projects cannot earn credits for building in areas with zero densities.
B Areas with high development density
C Areas with low development density
Projects cannot earn credits for building in areas with low densities.

D Areas that have not been previously developed
Projects cannot earn credits for building on lots that are not previously developed.
Notes:
Choosing urban areas that are previously developed with high development densities can earn LEED credit.
Question 75:
What is an example of climate change?
A A significant two-year increase in wind speeds
Climate change takes place over more than two years.
B A century-long increase in temperature by 1 degree
Climate change refers to any significant change in measures of climate (such as temperature, precipitation,
or wind) lasting for an extended period (decades or longer) (Environmental Protection Agency).
C A five-year drought
Climate change takes place over more than five years.
D An unexpected snowstorm in Phoenix
This is a weather condition.
Notes:
Question 76:
What is a footcandle?
A Measure of a surface's ability to reflect solar heat
This is solar reflectance.
B Measure of the quantity of light falling on a given surface
A footcandle is the measure of the quantity of light falling on a given surface. Minimizing foot candles helps
reduce light pollution which helps nocturnal wildlife and preserve nighttime views of the sky.
C The amount of liquid a material can pass through
This is a material's perviousness.
D The ratio of the radiation emitted by a surface to the radiation emitted by a black body at the same
temperature.

This is the definition of emissivity.
Notes:
While the definition is not present in the reference, the term is.
Question 77:
What does the success of an integrated project team depend on?
A The choice of materials used
Material choice doesn't make or break a project team.
B Commitment to the sustainability goals
Like any type of project success depends on sticking to the goals setup at the start.
C Building codes
The building codes would be reviewed first in the process. The design would revolve around those codes.
Since the codes would be followed from the start this should not be an issue.
D Meeting the project schedule
The project schedule is bound to fluctuate. Success is measured by the end product and if it met the goals,
not how long it took to build.
Notes:
Reference: Sustainable Building Technical Manual: Part II
Question 78:
Which statements are not true regarding LEED projects?
A Projects can earn an Innovation in Design credit by having an individual within the organization who is
already a LEED AP participate in the project
Individuals within the organization who are LEED APs can help earn an ID credit.
B Projects can earn an Innovation in Design credit by hiring an outside consultant who is a LEED AP to support
the project
Consultants or contractors outside of organization who are LEED APs can help earn an ID credit.
C LEED APs are required for projects that use the LEED Volume Program
The LEED Volume Program (formerly the USGBC Portfolio Program) enables owners to integrate the LEED
green building rating system into new and existing buildings in their company's portfolio, and do so in a cost

effective way without sacrificing the technical rigor and integrity of LEED. This program is a way to achieve
volume certification more easily.
D A LEED for New Construction project requires a LEED Green Associate to earn an Innovation in Design
credit
At this time a LEED Green Associate is not required for an ID credit.

Question 79:
A building has a parking garage with a total size of 100,000 SF. The parking garage has five levels of equal size.
What is the parking footprint?
A 10,000 SF
B 20,000 SF
Parking footprint refers to the area of the project site occupied by the parking areas and structures - since
the garage has 5 levels of equal size, the site area taken up by the parking garage is 20,000 SF.
The parking garage has a total size of 100,000 SF. There are 5 floors. 100,000 divided by 5 = 20,000 SF per
floor. The parking footprint is 20,000 SF.
C 50,000 SF
D 100,000 SF
Notes:
Question 80:
A project team has selected a previously developed lot in an urban area to build a new condominium. If the project
site is near a public park what would this help with?
A Reducing the heat island effect
The choice of site does not reduce the heat island effect.
B Increasing open space
Public parks do not contribute to open space for LEED projects. Open space is a measurement of the open
space within the LEED boundary.
C Increasing the development density
A public park does not increase development density.
D Community connectivity

A public park is a basic service.
Community connectivity is the quantity of connection between a site and the surrounding community. It is
measured by pedestrian access to housing basic services such as restaurants, post offices, hospitals,
libraries, etc.
Notes:

into the first national system for neighborhood design.
C LEED for Homes
D LEED for Schools
Question 82:
A contractor purchased some carpet containing VOCs that was manufactured 250 miles from the project site. What
LEED category would this material negatively impact?
A Indoor Environmental Quality
Carpet is one of the materials measured for VOC content as part of Indoor Environmental Quality. Others
include paints, coatings, furniture, and composite wood products.
B Sustainable Sites
Neither materials nor VOCs are addressed in this category.
C Innovation in Design
This would not negatively impact exemplary performance.
D Energy and Atmosphere
Neither materials nor VOCs are addressed in this category.
E Materials and Resources
All materials are calculated as part of the total cost of materials for the purpose of calculating the percent of
Regional Materials. This includes carpet.

Notes:
Question 83:
Which of the following strategies would NOT earn Innovation in Design / Operations credit?
A Evaluating the life-cycle assessment of a project's products to show their environmental benefits
LEED does not endorse any product. However an innovative strategy is for project teams to show the
products/materials used on a project are more sustainable than alternatives.
B Implementing an educational outreach program
Green education is one of the most common innovation points projects often add. These programs outline
the green building strategies used in the building. The programs may include self-guided tours or computer
kiosks in the main entryway of the building so visitors can learn about the building.
C Implementing a green parking design
Reducing the parking requirements is covered in LEED in the reduced parking design credits.
D Having stakeholders divert and recycle waste from sources other than the building project
Onsite recycling is a prerequisite in most of the rating systems. This innovative strategy goes beyond that by
having occupants or stakeholders come up with a recycling program for outside waste. Consider having one
day per quarter where the community can drop off old electronic equipment that would otherwise end up in a
landfill.
Question 84:
Which of the following refrigerants has the least global warming potential?
A CFC-11
CFC-11 and CFC-12 both have high GWPs.
B CFC-12
CFC-11 and CFC-12 both have high GWPs.
C HFC-23
HFCs have low ODPs but high GWPs.
D HCFC-123
While you don't need to memorize the entire table of ODP and GWP values, note that while HFCs deplete
less ozone, HCFC-123 causes less global warming than any HFC.
Notes:

Question 85:
What term refers to the investigation and valuation of the environmental impacts of a given product or service caused
or necessitated by its existence?
A Life cycle assessment
B Hard cost
By far the largest portion of the expenses in a construction budget, the hard costs are mostly comprised of
the actual construction costs incurred to build the project. The hard-cost categories are the bricks and mortar
of the project. Examples of hard costs include masonry, wood, steel, carpet, tile, mechanical systems,
roofing.
C Life cycle costing
performance.
D Soft cost
A soft construction cost is one that is not directly related to building, construction, etc. These include building
permit fees, architect fees, legal, financing, engineering fees, commissioning, and other costs incurred
before and after construction.
Notes:
Life cycle assessment (LCA) is the investigation and valuation of the environmental impacts of a given product or
service. LCA evaluates environmental performance. This view takes into account the whole life of a product or project
(not assessing it from a single point in time).
Question 86:
What is the building footprint?
A Area of the building structure only
The development footprint is the area affected by project site activity. The building footprint is the area of the
site occupied by the building structure.
B Entire project boundary
C Building structure and landscapes
D Building structure and hardscapes
Notes:

Question 87:
Potable water is defined as:
A Water that is not treated to drinking water standards and is not meant for human consumption
This is the definition of non-potable water.
B Wastewater from bathroom sinks, laundry machines, kitchen sinks and dishwashers
Water that has come in contact with food through kitchen sinks and dishwashers is usually classified as
blackwater.
C Untreated house-hold wastewater which has not come into contact with toilet waste or kitchen sinks
This is graywater.
D Water that meets or exceeds EPA's drinking water standards
Potable water meets or exceeds EPA's drinking water standards. Potable water can be used for any
purpose, though the intent of the water efficiency credits is to reduce the use of potable water.
Notes:
Question 88:
The process of green building begins with the idea of the project and continues until:
A The project begins operating
B The schematic design is completed
C The construction documents are prepared
D The project is reused or recycled
Green building continuously improves a project from when the idea is first realized in a person's head to
when the project is finally either reused for a different purpose or it is demolished and hopefully recycled.
This differs from conventional design where all trades are not involved in all parts of the process through the
project's life cycle.
Question 89:
What is the minimum certification level in LEED?
A Certified
The LEED levels are Certified, Silver, Gold, and Platinum.

B Accredited
Buildings are certified, people are accredited. Sometimes people get that backwards.
C Approved
There is no 'Approved' certification level for LEED.
D certified
'certified' with a lowercase 'c' is incorrect.
Question 90:
What has the lowest priority in building design?
A LEED Rating System
Although the LEED Rating System is critical to a successful green building project, all local, state, and
federal codes and regulations have precedent over any LEED standards. A project team can't ignore local
codes in favor of a green building strategy. Both must be addressed.
Certain locales have their own set of green codes, which must be addressed as well.
B Plumbing codes
C Fire protection codes
D Local building codes
Local building codes represent the minimum codes that a project must adhere to.
State and local jurisdictions may develop their own regulations or adopt building codes based on national
model codes. State and local codes are typically based on national model codes published by the
International Code Council (ICC)
Question 91:
What statement is true regarding HydroChloroFluoroCarbons (HCFCs)?
A HCFCs are a type of natural refrigerant
HCFCs are not in the class of natural refrigerants.
B HCFCs are the refrigerants with the least direct impact on the environment
Natural refrigerants, not HCFCs, are the refrigerants that have the least direct impact on the environment.
C Zero use of HCFCs is required to achieve Fundamental Refrigerant Management
Zero use of CFCs, not HCFCs, is required to achieve Fundamental Refrigerant Management under LEED.
D HCFCs have a low ozone depletion potential compared to CFCs

HCFCs have a low ozone depletion potential compared to CFCs.
Notes:
HCFCs are schedule to be phased out under the Montreal Protocol.
Question 92:
Which of the following is an example of a source control waste reduction strategy?
A Pre-ordering materials cut to size
Source reduction is the first and best way to minimize waste. Source reduction starts at the source-such as
pre-ordering materials cut to size and choosing modular construction, which generates less onsite waste.
B Reusing salvaged materials onsite

Question 93:
What statements are true regarding the LEED for Commercial Interiors rating system?
A The rating system requires HVAC replacement
HVAC replacement is a major renovation and would fall under LEED for New Construction.
B This rating system can only be used if envelope upgrades are done
Envelope upgrades are a major renovation and would fall under LEED for New Construction or LEED for
Core & Shell.
C This rating system is appropriate for spaces that are undergoing a complete interior fit-out of at least 60% of
the certifying gross floor area
This rating system is appropriate for interior spaces that are undergoing alteration work for at least 60% of
the certifying gross floor area.
D Projects are only eligible if the tenants purchase the space
Tenants don't normally purchase space, they lease space. In either case LEED for Commercial Interiors can
be used.

Notes:
Question 94:
Installing photovoltaic cells on a building's rooftop will help with what green building area?
A Recycled Materials
Mechanical equipment cannot be included in the recycled materials calculations.
B Fundamental Refrigerant Management
Fundamental refrigerant management addresses zero use of CFCs in a building's base HVAC&R systems.
C Green Power
Green power is offsite renewable energy.
D Onsite Renewable Energy
Onsite renewable energy is used to reduce the energy demand from grid sources, such as coal burning
plants. Photovoltaic cells, or solar panels, are one of the most common types of onsite renewable energy.

Question 95:
How would a project team member determine if a credit has Regional Priority?
A Look at the LEED credit checklist
The LEED Credit Checklist helps project teams track their credits against requirements for certification. The
LEED Credit Checklist is also called the LEED Scorecard.
B Check the appropriate LEED reference guide
The LEED reference guides do not contain information on which credits are most important to which region.
C Visit the USGBC website
Regional Priority credits are listed in an Excel spreadsheet and available from USGBC's website.
Do not confuse the following terms:
Regional Priority Credits - these are bonus points for encouraging teams to attempt LEED credits that
address specific environmental priorities in the project's region. Each zipcode in the U.S. has 6 LEED credits
that are extra important to that zipcode. A project that achieves one of those credits earns a bonus point, up
to a maximum of 4. Here is an example. In Georgia zipcode 30002 saving water is important, because
Georgia has had a lot of droughts lately.
Regional Materials - building materials or products that have been extracted, harvested or recovered, as well
as manufactured, within 500 miles of the project site.

Regional Variations - These are only found in reference guides and are specific to each credit. A regional
variation 'outlines concerns specific to the geographic location of the building'. For example in some areas
there aren't great recycling programs, or they may be nonexistent. In regards to construction waste
management the regional variation states 'hey, check your local recycling program before you get to deep
into this credit because if you can't recycle anything your chances of earning the credit go down'.
D Submit a Credit Interpretation Ruling (CIR)
CIRs are used for technical guidance on credits. Anyone on the project team can submit a CIR, as long as
the person has access to LEED Online (through the project administrator).

Question 96:
What is adaptive reuse?
A The renovation of structures or spaces to improve their efficiency
This is not the correct definition.
B The design and construction of a building so that it can serve a future use that is different than its current use
Adaptive reuse is the design and construction of a building so that it can serve a future use that is different
than its current use. In this example the building can have offices now but in 20 years could be updated to
apartments more easily than if the design did not include this option.
C The refinishing or refurbishing of building materials
This is not the correct definition.
D Sustainable plans for built environments that improve existing conditions
This is regenerative design.
Notes:
Question 97:
Why does the USGBC outline rules on use of its trademarks and logos?
A USGBC wants customers to be directed to its website for clear information
This is a valid statement but not the primary reason USGBC created logo rules.
B USGBC wants to be able to charge a fee for logo use
Fees are not charged for logo use directly. If a company becomes a member the company must pay a fee
and then gets access to a logo.

C USGBC wants to make sure its message is spread accurately
This question pertains to exam objective I.P USGBC Policies (e.g., trademark usage; logo usage) from the
LEED GA Candidate Handbook.
While we receive many negative comments about the relevance of these types of questions the
subject matter may come up on your exam. You are better off seeing questions from every exam
objective than being under-prepared because some questions covering the GBCI exam objectives
you will be tested on seem silly.
The USGBC Trademark Policy assist the community in the use of USGBC proprietary marks and
corresponding language that accurately and consistently convey USGBC's messages and identity.
D USGBC wants to make sure it retains control over what is said about LEED
This is a valid statement but not the definition of the logo policies.

Question 98:
What strategy will reduce the rate of stormwater runoff?
A Install a detention pond
A dry pond (detention pond) is used to store excess stormwater. Dry ponds are basins whose outlets have
been designed to detain stormwater runoff for some minimum time (e.g., 24 hours). The stormwater will
slowly seep into the ground to recharge aquifers or discharge as determined by the pond design to allow
pollutants to settle. Unlike wet ponds, these facilities do not have a large permanent pool of water.
B Install nonporous surfaces with high SRI values
A nonporous surface will increase the rate of stormwater runoff.
C Install exterior surfaces with high SRI values
High SRI materials are reflective and help reduce the heat island effect.
D Install water efficient irrigation systems
Irrigation water runoff is not the same as stormwater runoff.
Notes:
Question 99:
LEED addresses ozone depletion by setting requirements on the following:
A Refrigerants
Refrigerants are a requirement that must be addressed for certification.

B Automobile use reduction
This impacts global warming.
C Green power use
This impacts global warming.
D Fire suppression system chemicals
The type of fire suppression system used effects ozone depletion.
Notes:
Question 100:
Can ozone have negative environmental effects?
A Yes, when located in the upper atmosphere
B No, ozone is essential to life on earth
C Yes, depending on where ozone is located
(O3) is a gas composed of three oxygen atoms. It is not usually emitted directly into the air, but at ground-
level is created by a chemical reaction between oxides of nitrogen (NOx) and volatile organic compounds
(VOC) in the presence of sunlight. Ozone has the same chemical structure whether it occurs miles above the
earth or at ground-level and can be 'good' or 'bad,' depending on its location in the atmosphere.
In the earth's lower atmosphere, ground-level ozone is considered 'bad.' Motor vehicle exhaust and industrial
emissions, gasoline vapors, and chemical solvents as well as natural sources emit NOx and VOC that help
form ozone. Ground-level ozone is the primary constituent of smog. Sunlight and hot weather cause ground-
level ozone to form in harmful concentrations in the air. As a result, it is known as a summertime air
pollutant. Many urban areas tend to have high levels of 'bad' ozone, but even rural areas are also subject to
increased ozone levels because wind carries ozone and pollutants that form it hundreds of miles away from
their original sources.
'Good' ozone occurs naturally in the stratosphere approximately 10 to 30 miles above the earth's surface
and forms a layer that protects life on earth from the sun's harmful rays.
D No, ozone is located in the upper atmosphere
