Wood A Natural Choice - How the Building Material Contributes to Sustainable ...Think Wood
This presentation contributes to the discourse on sustainability that is driving ongoing improvement in the way buildings are designed and constructed. Specifically, it focuses on the growing trends of wood use as a low environmental-impact building material and the effect green building rating systems have on design choices.
Materials in Action - Examining the Impacts of Building Materials Think Wood
When an architect specifies a building material, that choice casts a long shadow. While most of the environmental effects from materials occur during the extraction and production phases, they continue to influence a structures' environmental footprint long afterwards, throughout the operations phase and beyond. This presentation evaluates the environmental impact of building materials wood, concrete and steel.
Rethinking Wood as a Material of Choice – Costs less, Delivers moreThink Wood
Designers today are finding new possibilities in one of the oldest building materials on earth, wood. The building material has always been valued for its beauty, abundance and practicality, but many of wood’s inherent characteristics are rising to very current challenges. Wood’s traditional values and newest technologies meet in the projects presented in this course, illustrating the advantages of wood in four areas: cost-effectiveness in a wide range of projects; adaptability for use in challenging, visionary new designs; lower environmental costs throughout its life cycle, from its source in renewable, carefully managed forests, through an energy-efficient service life, and often on to a new, recycled and reimagined use; and a unique human-nature connection that has always been intuitive, but is now being documented in research.

Wood Scores A+ for Schools & Student HousingThink Wood
In educational facilities architects are called upon to achieve a wide range of objectives with limited budgets. An increasing number of designers are turning to wood-frame construction as a reasonable solution, it typically costs less while meeting all code and safety requirements. In addition, wood-frame construction offers advantages such as speed of construction, design versatility, and a light carbon footprint.
Cost-effective, code-compliant and sustainable, mid-rise wood construction is gaining the attention of design professionals nationwide, who see it as a way to achieve higher density housing at lower cost—while reducing the carbon footprint of their projects. Yet, many familiar with wood construction for two- to four-story residential structures are not aware that the International Building Code (IBC) allows wood-frame construction for five stories and more in building occupancies that range from business and mercantile to multi-family, military, senior, student and affordable housing. This presentation reviews the benefits of multi-story wood construction, the code requirements and discusses the design techniques used in multi-story wood construction.

"Green Building Technology is a Game Changer"
http://sourceable.net/green-technology-game-changers/
This seminar was presented by me on 2008, Although the rating point changes on the past years, still the body contains many rich information and case studies related to green buildings and sustainable design.
IGBC Green Factory Building Rating System is a voluntary and consensus based programme. The rating system has been developed based on materials and technologies that are currently available. This rating system would facilitate the development of energy efficient, water efficient, healthy, more productive, environmentally friendly factories.
The rating system evaluates certain credit points using a prescriptive approach and other credits on a performance based approach. The rating system is evolved so as to be comprehensive and at the same time user-friendly. The programme is fundamentally designed to address national priorities and quality of life for factory workmen.
The rating programme uses well accepted national standards and wherever local or national standards are not available, appropriate international benchmarks have been considered.
this presentation is about the green building concept. I have thrown some light on green building concept, its cost facts, why we need green buildings?, scope of green buildings and I have also described about my visit to a green building, about LEED, rating system of LEED, and some features of green buildings.
A green building is one which uses less water, optimizes energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants as compared to a conventional building
A presentation on several key drivers impacting the green building construction market. Highlights include regulations, legislation and incentives affecting designers, contractors and building owners. The presentation has been given publicly several times in 2009 and 2010.
ENERGY IN BUILDINGs 50 BEST PRACTICE INITIATIVESJosh Develop
Technology, economics and policy are rapidly transforming energy markets
and the broader economy. Global efforts to reduce emissions of greenhouse
gases are leading to increased focus on policies that can reduce energy use
or promote low emissions generation.
Australia’s economy-wide target under the United Nations Framework
Convention on Climate Change is to reduce emissions by 26-28 per cent
on 2005 levels by 2030. By the second half of the century, achieving net zero
emissions is likely to be necessary to meet international climate commitments.
The cost of producing electricity from renewable resources has declined
significantly over recent years and remains on a rapid downward trajectory.
Climate-responsive (passive) design is key to green buildings design and is based on the way a building moderates the climate for human good and well-being. Solar energy and wind energy can be effectively combined with climate-responsive design to produce electrical power by photovoltaic (PV) and wind turbines (WT). Today, urbanization and the increasingly dense populations of the world’s largest cities are pushing architects to reach for new heights in sustainable building skyscraper designs. But, there are a few green buildings in this world that capture the eye. This presentation provides a preview of Modern “eco-scrapers” that are bridging the gap between breathtaking building design and clean technological ingenuity .
On December 14, 2009, the Alliance to Save Energy and the Renewable Energy and Energy Efficiency Partnership (REEEP) held a side event at the COP15 climate conference in Copenhagen, Denmark, entitled, "Paradox to Paradigm: The Role of Energy Efficiency in Creating Low Carbon Economies."
International Journal of Engineering Research and Applications (IJERA) is an open access online peer reviewed international journal that publishes research and review articles in the fields of Computer Science, Neural Networks, Electrical Engineering, Software Engineering, Information Technology, Mechanical Engineering, Chemical Engineering, Plastic Engineering, Food Technology, Textile Engineering, Nano Technology & science, Power Electronics, Electronics & Communication Engineering, Computational mathematics, Image processing, Civil Engineering, Structural Engineering, Environmental Engineering, VLSI Testing & Low Power VLSI Design etc.

INTRODUCTION:
We have all heard about the impact of climate change that is brought about by burning of non-
renewable fuels and environmental degradation. The face of urbanization and the hard
surfacing of ever larger cities are also having an impact when the majority of the earth’s
population lives in cities. The built environment also consumes a significant amount of energy.
In Canada buildings use nearly one-third of our total energy, two-thirds of our electricity, one-
eighth of our water and transform land that provides valuable ecological resources. (CaGBC
web site)
Canadians consume 33% more energy per unit of GDP than the USA. The social impacts and
the cost of doing nothing will continue to rise as more GHG are released into the atmosphere
and the operating costs of conventional buildings increase. Unless there are fundamental
changes to the way we look at buildings and energy use, climate change will become more
pronounced. Like in the transition from the Stone Age to the Bronze Age eventually change
occurs due to a need to improve performances and reduce costs through innovative ideas.
Social demand is currently changing regulations such as the new Vancouver Building By-law
which takes effect January 1, 2015, requiring buildings to perform more efficiently. The intent is
to transition toward a sustainable developmental model. Being idealistic and reducing climate
change is nice but in a capitalistic economy change will not occur unless it makes business
sense and is cost effective. The Real Property Association of Canada is the “premier” industry
association for investment property leaders”, who’s member’s represent $150 billion in assets
and publishes an annual report on how its members are meeting its sustainability challenge.
Large property management companies, such as Ivanhoe Cambridge (owner of Guildford Mall
with assets of $40 billion), have dedicated staff and a sustainability policy to improve the
company’s bottom line and increase shareholder equity.
Standards provide a method of comparing building energy use against others buildings of
similar types in similar industries. The standards are verified by a third party so that others
looking at the building will know it is operated optimally and professionally. This can improve
resale and require less regulatory review for renovations. Some standards are more costly to
implement than others and the application of standards is dependent on the type of building,
new or existing.
The purpose of a building is for humanity to live and work. Improving the environmental quality
in the building improves the health for those inside. Using natural light, utilizing solar exposures,
good HVAC practices, having good outdoor views, all contribute to a healthy and productive
environment. LEED is a well-known green building standard for construction of public facilities.
BOMA BESt, BREEAM, Energy Star, Certified Passive House and the Living Building Challenge
are less known standards but will be compared in this report. When are they used and why?
This report outlines and provides a general comparison of each standard.
The demand for greener practices supports a growing market for green building products, such
as energy and water efficient fixtures. As new products are developed the cycle of continual

improvement of existing building systems is performed thereby further reducing energy
consumption. Education of best practices and innovation will lead to a broader understanding of
the interrelationship of various building systems and ultimately better performing buildings. The
BC Building Code is incorporating improved practices which have been verified through the
green building rating systems.
This report will focus on green commercial building rating systems. Lighthouse Consultants
completed a study in December 2014 outlining the performance of buildings in BC. Public
knowledge of these green building rating systems is limited and where do you go to find out
details of each? This report will give a brief summary of each so you can decide which green
rating system will work for you and provide a base for further investigation.
A BRIEF HISTORY OF EVENTS AND STANDARDS:
1842 Englishman Edwin Chadwick published Report on the Sanitary Condition of the
Labouring Population of Great Britain was the first time in history environmental conditions were
recognized as the cause of disease. This gave rise to the Public Health Act of 1875 which had
specific implications to buildings and neighbourhood developments.
1973 Energy crisis brought energy conservation to the International stage due to soaring
costs.
1975 ASHRAE develops energy Standard 90-1975 in response to the Energy Crisis. This
evolved into standard 90.1 which is widely referenced in many green building standards.
1978 US Congress passes the Energy Policy and Conservation Act which stated to receive
federal funds States would need to initiate energy conservation standards for new
buildings.
1982 R2000 Standard introduced in Canada.
1990 First certified Passive House was built in Germany. The rating system used information
from Saskatewan Conservation House which was built near Regina in 1977.
1992 US Environmental Protection Agency establishes the Energy Star program.
1998 The Barret Commission releases its final report on the “Commission of Inquiry into the
Quality of Condominium Construction in BC”.
2002 US Green Building Council introduces LEED standard.
2004 ASHRAE 90.1 Standard was applied to buildings, the envelope, and majority of the
mechanical and lighting systems.
2005 BOMA BC establishes the Go Green Plus Program.
4. 4
December 2014
2006 United States Green Building Council (USGBC) contributed to the development of a new
national minimum green building standard. Standard 189 was developed in partnership
with the American Society of Heating, Refrigeration and Air Conditioning Engineers
(ASHRAE), and the Illuminating Engineers Society (EIS).
2008 BC adopted improved energy and water efficiency requirements within the BC Building
Code.
2008 The European Union resolution calls on each member state to adopt the Passive House
Standard by 2016 for all new construction and major renovation projects.
2009 The CaGBC formally adopts the Living Building Challenge as an official program.
Through the Cascadia Green Building Council the institute offers focussed programs in
British Columbia.
2009 BOMA BC and BOMA Ontario rebranded the Go Green program into BOMA BESt
(Building Energy Standard)
2009 Energy Star performance standard replaced the R2000 Standard.
2010 California launches its Green Building Standards Code.
2012 International Energy Conservation Code (IECC) includes ASHRAE standard 90.1
2013 BC adopted the 2011 National Energy Code for Buildings (NECB) and ASHRAE 90.1
(2010) as compliance options in the BC Building Code for Large residential, Industrial,
and Commercial buildings.
2014 Nov 25, ASHRAE releases Standard 189.1 – Standard for the Design of High-
Performance Green Buildings. The International Code Council, ASHRAE, the American
Institute of Architects, the Illuminating Engineering Society of North America, and the US
Green Building Council sign a memorandum to collaborate on the development of future
versions of Standard 189.1
2014 Dec 19, BC Building Code will introduce energy efficiency requirements for houses and
small buildings (Part 9.36 Buildings).
2015 January 1, New Vancouver Building Bylaw (VBBL) 9419 becomes effective requiring
energy use be 20% less than 2007 levels for new construction.
WHY HAVE GREEN BUILDING STANDARDS:
In a recent study, EPA found that buildings that were benchmarked consistently reduced energy
use by an average of 2.4 percent per year. And, buildings that started out as poor performers
saved even more. See EPA’s Portfolio Manager Data Trends series for more information.

December 2014
In the U.S. green building construction grew from 2% in 2005 to 44% in 2012.1
This provides organizations a lower operating cost to remain competitive in a world economy.
A Green Building Rating Standard, is a system to compare the performance of similar building
types. Green buildings are designed to;
1. Efficiently use energy, water, and other resources.
2. Protect occupant health and improving employee productivity.
3. Reduce waste, pollution and environmental degradation.
The design of green buildings requires a holistic approach from a design team that can analyze
the optimum building systems. Once constructed into the building the buildings performance will
impact less on the environment and require less energy to maintain and operate.
One metric in the rating system is to measure a building’s Energy Use Intensity (EUI). The units
are KWh/m2
/year and are compared with other similar types of buildings. Other metrics such as
environmental qualities are also incorporated into a rating system.
One of the key requirements is a third party confirms the performance so that there is no bias in
the assessment. This provides building owners a standard to compare their performance in
relation to others, across similar asset classes.
Buildings that are certified to a recognised standard are more likely to have staff engaged in
activities linked with continuous improvement and will therefore benefit from operational
savings. Recertifying a building is strongly associated with improving the buildings performance
or as a minimum is maintaining the building in optimal performance. Some of the benefits are;
Lower operating cost.
Future proofing against competition and rising utility costs.
Future proofing against pending regulation. Simpler regulations when renovating.
Less environmental impact.
Improved occupancy comfort and productivity. Less sick days.
Attracts tenants who want to make a sustainability commitment.
Enables staff to understand how their facility is performing and how to make
improvements. Informed users adjust buildings controls to optimum.
Eligibility for responsible investment.
Company brand.
Simplified Reporting.

THE GREEN STANDARDS:
Green buildings are specifically designed structures that reduce the overall negative impact of
the built environment on human health and the natural environment by;
Efficiently using energy, water, land and materials
Protecting the occupant health and improve employee productivity
Reducing waste and pollution from each building
Continuously looking for ways to improve performance
High-performing green buildings address sustainable development throughout the building’s
entire life cycle. This is best achieved in the design phase where various options can be
analysed and modeled for optimum performance prior to construction. A collaborative design
team will analysis the pros and cons of each option that can impact across multiple building
systems. An example of this is green buildings are designed to be nearly air tight so require
good air circulation and exhaust air can be used to preheat the fresh air.
Imposing current green standards on existing structures is difficult and costly especially when
the building envelope may not be air tight and not constructed to current standards. However
improvements to building performance can be achieved, it is just to what degree it is cost
effective. As existing building systems need to be replaced new and improved equipment is
being added. Commissioning of new equipment can lead to the review of other building systems
that are interrelated.
There are a number of green building standards to assess a building with the most well-known
in Canada being LEED certification. This standard is required for all new public building
construction however it can be the most expensive to attain. Since 85% of buildings were
constructed prior to 1989 this does not work well for the existing building stock that has thin
walls and is not air tight.
A company’s formal environmental policy provides guidelines for the business operations as
well as demonstrates awareness and commitment to operating responsibly. A strong
environmental policy should include the precautionary principal which states that if an action or
policy has a suspected risk of causing harm to the public or environment companies should
even in the absence of regulation, take action to minimize harm.

1. LEED
LEED is a rating system that is recognized internationally as a standard of excellence for
green buildings in 150 countries. The US Green Building Council introduced the
Leadership in Energy and Environmental Design (LEED) standard in 2002. Currently
version 4 is being used. The US Green Building Council is the owner of the LEED brand
and it works because it recognizes that sustainability is at the center of all buildings
encompassing their design, construction and operation.
The Canadian Green Building Council (CaGBC) entered into a licencing agreement with
the US Green Building Council (USGBC) for exclusive implementation of LEED Green
Building Rating Systems in Canada. Since 2004 the CaGBC has certified over 1,800
LEED buildings and registered over 5,000, the second highest number in the world.
LEED is available for the following rating applications;
Commercial Interiors (CI)
Core and Shell (CS)
Existing Building: Operations & Maintenance (EBOM)
Neighbourhoods (ND)
New construction (NC)
Home (H)
The LEED Rating System consists of an explicit set of environmental performance
criteria organized in the following performance categories;
1. Sustainable sites
2. Water efficiency
3. Energy and Atmosphere
4. Materials and Resources.
5. Indoor Environmental Quality
6. Innovation and Design process
Projects earn points toward certification by meeting or exceeding each Credit’s technical
requirements. All prerequisites must be achieved in order to qualify for Canada Green
Building Council certification. Points add up to a final score that relates to four possible
LEED certifications; CERTIFIED, SILVER, GOLD, or PLATIUM. Refer to the attached
Table 2 for the score corresponding to the certification. The point scoring can be found
on the CaGBC web site for each of the 6 modules listed above.
A study by Lawrence Berkley National Laboratory determined that the median cost of
retro-commissioning a building using LEED is approximately $0.27 per ft2
. This results in
an average energy savings of 15%, and an average payback period under 1 year. A
listing of existing LEED certified buildings and scope of work summary can be found on
the Whole Building Design Guide web site.

LEED EBOM was introduced in Canada in 2009 and is suitable when a building was
initially certified to LEED NC or CS and for medium to large facilities. To date 7 buildings
have been certified in British Columbia.
LEED certification involves the following steps;
1. Determine which rating system to use.
2. Register the project to show intent. The project is then referred to as a LEED
Certification Candidate and will be listed in the CaGBC’s public database. Owners
may opt out of the database if they choose.
3. Submit the certification application and pay a certification fee. Fees are related to
building type, square footage, and for members or non-members. A “Responsible”
professional is to fill out the required information per the reference guide. Typically
this is the LEED Accredited Professional who is coordinating the process.
4. Wait for the application review.
5. Receive the certification decision which can be accepted or appealed.
9. 9
December 2014
LEED accredited professionals can have the following designations;
LEED Green Associate: 2 day course and pass a 2 hour exam.
LEED AP (Accredited Professional) have demonstrated experience with a Specialty
such as:
1. Design and Construction, (BD+C)
2. Operation & Maintenance (O&M)
3. Interior design & construction (ID+C)
4. Design & Construction of Green Homes (HOMES)
5. Design & Development of Neighborhoods (ND)
LEED AP Fellow: Distinguished LEED AP’s, 8 years LEED Certification, 10 years in the
green building field.
LEED Rater: in field verification. Minimum 3 years working in residential building
construction, completed a number of specific Green Home courses, have the LEED AP
with Homes, served as a principal project team member on a LEED for Homes project,
pass the Green Rater Eligibility Qualification exam.
2. BOMA BESt
Building Owners and Management Association (BOMA) members understood the need to
provide a standard to compare building performance. BOMA BESt was established in 2003
by the industry for the industry prior to LEED EB. It would have been prohibitively expensive
to bring existing building envelopes to LEED standard so the certification was a pragmatic
approach to creating more sustainable buildings. BOMA BESt gives the users an online
toolkit to improve energy conservation and environmental responsibility in a cost effective
method.
BOMA BESt was designed by Canada’s leading building owners, managers and operators
in conjunction with a wide range of independent external experts to provide a consistent
framework for assessing and improving the environmental performance and management of
buildings. Since the inception of the program it has seen a tremendous uptake by the
Canadian real estate industry so that by the end of 2013 3,562 buildings have been certified
nationally. Their members and tenants understood the benefits for all stakeholders and it
made good business sense.
In 2009 the Ontario and BC Chapters merged and rebranded the Go Green and Go Green
Plus programs to BOMA BESt (Building Environmental Standards). Their mission statement
is to “Transform buildings into environmentally responsible assets”. The program is licenced
to BOMA Canada under the name BOMA BESt. In January 2012 BOMA Version 2 was
released. Highlights of the program are;
Certification is good for 3 years. Then if not recertified it will be dropped from the
National List. This encourages continued reviews and improvements.
10. 10
December 2014
Incorporates 14 Best Practice requirements for certification.
Online assessment surveys specific to various types of buildings.
Third party on-site verification.
Transparent scoring.
Updated energy and water benchmarking (accounts for increasing levels of
industry performance)
The four levels of the rating system are;
Level 1: Meet BOMA Best Practices
Level 2: Met the Best Practices and scores 70% to 79%.
Level 3: Met the Best Practices and scores 80% to 89%.
Level 4: Met the Best Practices and scores 90% to 100%.
Only Shaw Tower and Shangri-La tower are certified to level 4 in BC.
Certification can be for offices, shopping centres, open air retail plazas, light industrial buildings,
multi residential buildings and health care facilities. The process is set up for building
professionals to enter their data on-line. Verification is conducted by a third party to confirm
validity of the information. Recertification is required every 3 years and the public can search the
database of certified buildings.
BOMA BEST CERTIFICATION PROCESS
Key findings of a December 2014 study by Light House Sustainability Building Centre was that
BOMA BESt buildings that re-certified reduce energy and water consumption by 25-30% within
3 years, and reduced waste by 8%. Organizations with BOMA BESt certified buildings will soon
be recognized under the new Vancouver Building By-law (VBBL) as an exception from the
sustainability upgrades that would otherwise be mandatory. This will save building owners time
and money on renovations.

The Green Globes green building rating is also administered by BOMA but was rebranded into
the BESt program. Table 1 shows the results of BOMA BESt program since 2008.

LEED EB:O&M is fundamentally different by setting minimum performance requirements in
6 areas which existing buildings may not be able to achieve. BOMA BESt sets realistic goals
and a practical approach to improving the building performance. The Industry has set a
target for energy unit intensity (EUI) of 20 ekWh/ft2
/year (37.2 eKWh/m2
/year) by 2015 which
would make Canada a leader in conservation efforts.
3. BREEAM
BREEAM is a set of international standards for best practice in sustainable building
design, construction and operation. It encourages designers, clients and others to think
holistically about low carbon and low impact design even before considering energy
efficiency. The BREEAM web site advertises it will add a 2% increase in cost to new
building construction with a 2 to 5 year payback period through reduced utility costs.
The first step is to decide on which “Scheme” or method to apply, which are;
Scheme Application
Communities Planning stage of communities
New Construction 2011 Design & construction of new buildings
Code for Sustainable
Homes
Design and construction of domestic buildings
In-Use In-use assessment of an existing building
Refurbishment Refurbishment and Renovations
12. 12
December 2014
BREEAM works on the following Principals:
1. Sustainable solutions. Energy, pollution, ecology, materials, waste,
water, transportation, and the life cycle of the building.
2. Provides a framework to balance business needs with long term sustainability.
3. Sound Science. Provides technical sciences through a broad range of industry and
scientific experts to develop its Schemes.
4. Supports change by rewarding for building above the standard building regulations.
5. Delivers value to the occupants. Meets the needs of the occupants in a cost effective
manner over the life of the building that works within the limits of the earth’s finite
resources.
The next step is to contact a licenced BREEAM Assessor or Auditor. In Canada there is
only one available in Toronto. They will explain the remaining steps to register for an
assessment. They are an impartial certifier for the project and review the information
provided by the project team.
Assessors take training courses specific to the Scheme they require. Once the courses
are completed and pass a test, the applicant will get registered with BREEAM.
4. ENERGY STAR PORTFOLIO MANAGER
EnerGuide is the Canadian equivalent to the popular Energy Star program in the US.
Since 2001 Canada has been an international partner in the US ENERGY STAR
program. Energy Star is a recognised energy labeling tool used throughout North
America. EnerGuide has options and tools for house construction which is not within the
scope of this report.
Portfolio Manager is an on-line interactive energy management tool of Energy Star for
tracking and assessing building energy and water consumption. It is used to do energy-
use analysis to compare the Energy Usage Index (EUI) to National averages. 12 to 36
months of energy cost data is required to analyse. Numerous comparisons, indicators
and performance metrics are available through preloaded and customizable reports
within the software. Property owners and managers can assess;
1. Existing Buildings
2. Commercial New Construction
3. Industrial Energy Management
4. Small Business
Portfolio Manager is a software tool to track energy, water and GHG emissions from any
building and provides a score between 1 and 100 to compare with similar building types.
An ENERGY STAR certification is awarded to those buildings that perform better than
13. 13
December 2014
75% of all similar buildings within the Energy Star database. An architect or professional
engineer must verify that information contained on the application is correct. In 2013
more than 300,000 buildings had used Portfolio Manager to benchmark their buildings
with 20,407 achieving Energy Star Certification in 2012. (Spring 2013 Energy Star
Snapshot report)
Energy Star provides Guidelines for Energy Management which provides a step by step
approach to manage a buildings energy performance. Natural Resources Canada has a
searchable database of approved providers.
The 75 percentile is a moving target that trends higher as more buildings improve their
performance and are added to the database. Similarly, if buildings are not performing
well the threshold will be trending lower.
Energy Managers, Owners and Operators are able to track a single facility or a group of
buildings for site energy, source energy, energy intensity, utility costs, greenhouse gas
emissions, personalized performance targets, and many other indicators over many
years. Certification is after 12 months of post construction utility data is received and
verified by a professional engineer or Architect familiar with buildings and their systems.
14. 14
December 2014
As an incentive ENERGY STAR recognizes;
1. ENERGY STAR Partner of the Year – Excellence in Energy Management
2. ENERGY STAR National Buildings Competition – Using Portfolio Manager track
energy performance to see who can achieve the greatest energy savings.
3. ENERGY STAR Challenge for Industry – Industrial sites that pledge to reduce their
energy intensity by 10% with 5 years.
The 7 main steps in Energy Star Guidelines
5. PASSIVE HOUSE
Passive House (PH) is not restricted to house construction. It applies to any building that
meets the standards outlined below. There are 9 buildings in Canada that are certified
as PH as of 2013. More Passive Houses are currently under construction in Vancouver
and will be completed soon. According to Alexander Maurer, of Marken Design +
Consulting, a PH may soon get a LEED rating so the 2 systems can be compared.
The standards required for PH certification are;

Projects are result orientated to leave the designer flexibility to innovate and match the
best materials and practices with the region. For this reason a certified PH designer
should be involved early in the project.
Achieving PH certification in a renovation is not always a realistic goal. For such
buildings the PH Institute has developed EnerPHit for certified energy retrofits with
Passive House Components. This requires either a maximum heating demand of 25
KWh/m2
/year or the consistent use of PH components in accordance with the
requirements for PHI certification of components.
If a building is PH Certified and goes through a renovation it will continue to be certified
as long as the building envelope is not altered.

PH construction is being made easier by BC Passive House which is a company that
constructs the prefabricated “superinsulated” wall panels in Pemberton. The panels are
shipped throughout North America and will speed up the construction time of a PH
building.
The Passive House Institute has a searchable database of Certified Passive House
Designers for any country in the world. A certifier for PH must pass an exam issued by
the PH Institute through authorized examiners worldwide. Seminars and courses to
prepare for the exam are provided through the same examiners. Alternatively the
applicant will need to submit a report of documented projects. Their certification must be
16. 16
December 2014
renewed every 5 years with at least 1 qualified approved Passive House construction
project.
6. LIVING BUILDING CHALLENGE
The Living Building Challenge (LBC) is a program of the International Living Future
Institute (ILFI). It is a philosophy, advocacy tool and certification program that addresses
developments at all scales. It is not a net neutral program but creates a pathway and
vision for a sustainable regenerative living future. It is a continually evolving program,
promoting a holistic approach, receiving feedback from design teams from around the
world.
In Canada the International Living Future Institute partners with the CaGBC to advance
and support the Challenge. Through the Cascadia Green Building Council the institute
offers a group of programs in British Columbia such as Living Community Challenge for
neighbourhoods that would share services.
Projects can receive the following certification;
1. Living Building Certification
2. Petal Recognition
3. Net 0 Energy Building Certification
The process follows 3 steps;
1. Register the project. Project details are entered including Typology and
Transect.
2. Documentation & Operation. Technical assistance is provided by the Institute
which can provide clarification if required. Projects require 12 months of
performance data and pay certification fees.
3. Audit & Certification. Once all documentation is provided an independent
auditor performs review of the site and documentation.
The evaluation criteria includes; specified percentage of local products, financial
contribution to Carbon Exchange to offset total embodied CO2 impact, does not use red
list of materials which are harm full to the environment, low volatile organic compounds
(VOC ) in materials, promotes a healthy and happy interior environment, equitable
access for all regardless of age handicap or social status, elevate spirits, celebrate
culture & spirit appropriate to its function, integrate public art, provide education material
about the operation and performance of the project, motivate others to make change,
design human transportation, reduced waste during construction and operation and end
of life reuse or demolition.
The applicant is also to donate to renewable infrastructure charity of their choosing or an
ILFI charity, $0.005 for every $1.00 of project cost.
17. 17
December 2014
The project also requires a Social Justice Action JUST endorsement. This is an
innovative transparency program by ILFI for organizations to reveal much about their
organizations including voluntary disclosure of how they treat employees, where they
make their financial and community investments.
Summary Matrix
COMPARRISON:
A comprehensive comparison of green building standards would require reviewing the details of
the scoring criteria for each standard. This is beyond the scope of this report. This report
provides a list of standards used in Canada and a general summary of each. There is some
overlap of the use of the standards listed so it is hoped to provide a general understanding of
what is available and when it is used.
Buildings built to a green building standard need to maintain their level of efficiency. Regular
recertification ensures this is being done.
18. 18
December 2014
Implementing green initiatives on existing buildings requires continuous recommisioning as new
and improved products and innovations become economical to implement. In both cases a
process of regular review is required to as a minimum maintain the building in optimum
performance. The general steps required for energy “Labeling” commercial buildings in Canada
are;
Step 1 Compile the actual energy and water used based on 12 months (or more) of utility bills.
You can’t manage what you don’t measure.
Step 2 Enter utility data in a building bench marking tool that will normalize the data for weather.
Step 3 Generate the energy use index (EUI) in eKWh/m2
/year, to compare to other similar
building types.
Step 4 Conduct an analysis of the building operations related to illumination, ventilation, thermal
comfort and compliance to ASHRAE guidelines.
Step 5 Provide a building energy efficiency recommendation report and plan for implementation
of the recommendations. Continuous energy data analysis and benchmarking will provide actual
energy savings from the upgrades completed. Go to Step 1 and repeat the process.

SUMMARY:
This report summarizes 6 green building rating standards used in Canada for commercial
buildings. They all have their application to improving building performance and sustainability for
the owner’s preference.
Reducing the demand on energy sources improves the capacity for those resources within
existing utility transmission capacity. Such as reducing water consumption will reduce the need
for municipalities to increase water supply pipeline capacity and on the downstream side
sewage trunk lines and sewage treatment plant capacity. This would reduce a significant
expenditure for municipalities to tax their citizens.
Locally residents in parts of the Township of Langley and the Gulf Islands who are not serviced
with municipal water have cisterns or wells, and have to reduce their water consumption during
the dry summer months when ground water levels go lower. Public demand creates a need to
reduce and conserve the resource.
The minimum standard any building is to be constructed is to the BC Building Code. This code
is being revised to include proven green building innovations. The trend is that more revisions
will be occurring in the future “greening” the code. The new Vancouver Building code requires a
reduction in energy use and will be effective January 1, 2015. These changes require an
informed and educated workforce to prepare for the changes occurring in the industry.
The green standards in this report are being revised over time which will decrease the impact on
the environment in and around buildings, further reducing operating costs. The diagram below
graphically shows the incremental move in standards toward a Net 0 building impact.
Impact of LEED on BC Building Code
21. 21
December 2014
The introduction of green building standards is the start of a trend to change the mindset the
industry looks at building use, optimizing the built environment for health, and the options
available throughout the life cycle of a building. Building green makes business sense, ensuring
the building is continually optimized to maintain its value.
The trend in green buildings will have a significant impact on the built environment. Building life
cycle costs will be reduced and the utility services (electricity, gas, water, sewer, storm) they
require will be reduced, which will provide significant savings for all.
