2. WHAT IS LEED?
Leadership in Energy and Environmental
Design
1. The LEED system was incepted and developed by U.S.
Green Building Council in 1998.
2. Intended to provide a concise framework for identifying and
implementing practical and measurable green building
design, construction, operations and maintenance
solutions.
3. WHAT IS LEED?
3. An internationally recognized green building certification
system, providing third-party verification that a building or
community was designed and built using strategies
intended to improve performance in metrics such as:
a) energy savings,
b) water efficiency,
c) CO2 emissions reduction,
d) improved indoor environmental quality,
e) and stewardship of resources and sensitivity to their
impacts.
4. 4. LEED is an open and transparent process where the
technical criteria proposed by USGBC members are
publicly reviewed for approval by the almost 20,000
member organizations that currently constitute the
USGBC.
5. The Green Building Certification Institute (GBCI) was
established by USGBC to provide a series of exams to
allow individuals to become accredited for their
knowledge of the LEED rating system. This is recognized
through either the LEED Accredited Professional (LEED
AP) or LEED Green Associate (LEED Green Assoc.)
designation.
WHAT IS LEED?
5. 6. GBCI also provides third-party certification for projects
pursuing LEED
7. More than 7,000 projects in the United States and 30
countries covering 1.062 billion square feet (99 km²) of
development area had been LEED certified.
WHAT IS LEED?
6. WHAT ARE THE LEED
CONSIDERATIONS?
1. Sustainable Sites
2. Water Efficiency
3. Energy & Atmosphere
4. Materials & Resources
5. Indoor Environmental Quality
6. Locations & Linkages
7. Awareness & Education
8. Innovation in Design
9. Regional Priority
7. Sustainable Sites –
1. Discourages development on previously
undeveloped land;
2. Seeks to minimize a building's impact on
ecosystems and waterways;
3. Encourages regionally appropriate
landscaping;
4. Rewards smart transportation choices;
5. Controls stormwater runoff;
6. and promotes reduction of erosion, light
pollution, heat island effect and
construction-related pollution.
8. Water Efficiency
1. Encourage smarter use of water, inside and out.
a) Typically achieved through more efficient
appliances,
b) fixtures and fittings inside
c) and water-conscious landscaping outside.
9. Energy & Atmosphere
According to the U.S. Department of Energy,
buildings use 39% of the energy and 74% of the
electricity produced each year in the United States.
The Energy & Atmosphere category encourages a
wide variety of energy-wise strategies:
1. commissioning;
2. energy use monitoring;
3. efficient design and construction;
4. efficient appliances, systems and lighting;
5. the use of renewable and clean sources of
energy, generated on-site or off-site;
6. and other innovative measures.
10. Materials & Resources
During both the construction and operations
phases, buildings generate a lot of waste and
use large quantities of materials and resources.
The Materials & Resources category encourages
1. the selection of sustainably grown, harvested,
produced and transported products and
materials.
2. It promotes waste reduction as well as reuse
and recycling, and it particularly rewards the
reduction of waste at a product’s source.
11. Indoor Environmental Quality
The U.S. Environmental Protection Agency
estimates that Americans spend about 90% of
their day indoors, where the air quality can be
significantly worse than outside. The Indoor
Environmental Quality category:
1. promotes strategies that improve indoor air
2. as well as those that provide access to
natural daylight and views
3. and improve acoustics.
12. Locations & Linkages
The LEED for Homes rating system recognizes
that much of a home's impact on the
environment comes from where it is located and
how it fits into its community. The Locations &
Linkages category encourages:
1. building on previously developed or infill
sites and away from environmentally sensitive
areas.
2. Credits reward homes that are built near
already-existing infrastructure, community
resources and transit – in locations that
promote access to open space for walking,
physical activity and time outdoors.
13. Awareness & Education
The LEED for Homes rating system
acknowledges that a home is only truly
green if the people who live in it use its
green features to maximum effect. The
Awareness & Education category encourages
home builders and real estate professionals
to provide homeowners, tenants and
building managers with the education and
tools they need to understand what makes
their home green and how to make the most
of those features.
14. Innovation in Design
The Innovation in Design category provides
bonus points for projects that use
innovative technologies and strategies to
improve a building’s performance well
beyond what is required by other LEED
credits, or to account for green building
considerations that are not specifically
addressed elsewhere in LEED. This category
also rewards projects for including a LEED
Accredited Professional on the team to
ensure a holistic, integrated approach to
the design and construction process.
15. Regional Priority
USGBC’s regional councils, chapters and
affiliates have identified the most important
local environmental concerns, and six LEED
credits addressing these local priorities have
been selected for each region of the country. A
project that earns a regional priority credit
will earn one bonus point in addition to any
points awarded for that credit. Up to four
extra points can be earned in this way.
16. Rating system
LEED has evolved since its original inception in 1998 to more
accurately represent and incorporate emerging green
building technologies.
LEED NCv1.0 was a pilot version.
These projects helped inform the USGBC of the
requirements for such a rating system, and this knowledge
was incorporated into LEED NCv2.0.
LEED NCv2.2 was released in 2005,
and v3 in 2009.
Today, LEED consists of a suite of nine rating systems for the
design, construction and operation of buildings, homes and
neighborhoods. Five overarching categories correspond to
the specialties available under the LEED Accredited
Professional program. That suite currently consists of:
17. Green Building Design & Construction
LEED for New Construction
LEED for Core & Shell
LEED for Schools
LEED for Retail: New Construction and Major Renovations
LEED for Healthcare
Green Interior Design & Construction
LEED for Commercial Interiors
LEED for Retail: Commercial Interiors
Green Building Operations & Maintenance
LEED for Existing Buildings: Operations & Maintenance
Green Neighborhood Development
LEED for Neighborhood Development
Green Home Design and Construction
LEED for Homes
LEED also forms the basis for other sustainability rating systems such
as the Environmental Protection Agency’s Labs21.
18. After four years of development, aligning credits across
all LEED rating systems and weighting credits based on
environmental priority, USGBC launched LEED v3,[4]
which consists of a new continuous development
process, a new version of LEED Online, a revised third-
party certification program and a new suite of rating
systems known as LEED 2009. In response to concerns
that LEED's requirements are cumbersome and difficult
to learn, in 2009 USGBC supported the development by
BuildingGreen, LLC of LEEDuser, a third-party resource
that contains tips and guidance, written by professionals
in the field, on applying LEED credits and the LEED
certification process.[5]
19. LEED 2009
In LEED 2009 there are 100 possible base points plus
an additional 6 points for Innovation in Design and 4
points for Regional Priority. Buildings can qualify for
four levels of certification:
Certified - 40 - 49 points
Silver - 50 - 59 points
Gold - 60 - 79 points
Platinum - 80 points and above
Note that the LEED for Homes rating system is
different from LEED v3, with different point categories
and thresholds that reward efficient residential design.
20. PROCESS
LEED certification is obtained after submitting an
application documenting compliance with the requirements
of the rating system as well as paying registration and
certification fees.
Certification is granted solely by the Green Building
Certification Institute (GBCI), which is responsible for the
third party verification of project compliance with LEED
requirements.
The application review and certification process is handled
in LEED Online, USGBC's web-based tool that employs a
series of active PDF forms to automate filing documentation
and communication between project teams and GBCI's
reviewers.
21. EFFECTIVENESS
A 2003 analysis of the savings from green building found
from a review of 60 LEED buildings that the buildings
were on average 25-30% more energy efficient, but it also
attributed substantial benefits to the increased
productivity from the better ventilation, temperature
control, lighting control, and reduced indoor air
pollution.[7]
22. TYPES OF LEED INITIATIVES AND
INCENTIVES:
. A full listing of government and school LEED
initiatives can be found online and is updated regularly.
Some areas have implemented or are considering
incentives for LEED-certified buildings.
The city of Cincinnati, Ohio adopted a measure
providing an automatic 100% real property tax
exemption of the assessed property value for newly
constructed or rehabilitated commercial or residential
properties that earn a minimum of LEED Certified.[21]
23. Incentive programs
Many local governments have adopted LEED incentive
programs. Program incentives include tax credits, tax
breaks, density bonuses, reduced fees, priority or
expedited permitting, free or reduced-cost technical
assistance, grants and low-interest loans.[24][25]
