The LEED Canada-NC 1.0 Rating System and Reference Guide was written and adapted primarily by Dr. Raymond Cole of the Environmental Research Group of the University of British Columbia’s School of Architecture, under contract to the Canada Green Building Council. Stephen Carpenter of Enermodal Engineering Ltd., chair of the CaGBC LEED Technical Advisory Group, was the volunteer primary author of the Energy & Atmosphere chapter. Both devoted far more time and effort than the CaGBC could possibly compensate them for; we could not have been blessed with better authors and volunteers.

The authors were greatly assisted by research, review and suggestions by many CaGBC Technical Advisory Group, LEED Steering Committee and MURB Task Force members, as well as many non-CaGBC volunteers. In particular, Curt Hepting of Enersys Analytics was responsible for several studies that helped defi ne critical details of the Energy & Atmosphere Credits, and resolve many issues of energy simulation. For their valuable research and contributions to developing LEED Canada-NC 1.0 Credit descriptions and requirements, thanks are due to:

• Diana Klein, Read Jones Christoffersen Ltd.• Maggie Wojtarowicz, EcoSmart• Michel de Spot, EcoSmart• Robert Marshall, Cedaridge Services Inc.• Sheila Brown, Innovative Management Solutions Inc.• Linda Bily, Environment Canada• Janika McFeely, UBC School of Architecture

Reference package production was managed by the CaGBC LEED Program Manager, Ian Theaker, who also authored the Indoor Environmental Quality chapter. Other Canada Green Building Council staff who contributed greatly to Reference Guide production include Erika Mayer, CaGBC National Coordinator; Luana Mirella, Membership and Communications Coordinator; and Christine Fortin, Membership and Communications Coordinator. Finally, Alex Zimmerman, president of the Canada Green Building Council, led the staff and volunteer teams, providing the clear head and sober second thought that resolved many thorny issues.

The following is a partial list of contributors and volunteers who made LEED Canada-NC 1.0 possible; apologies are due to those we have missed.

Special ThanksThe creation of the Canada Green Building Council’s LEED Canada Rating System and its supporting documents are due in large part to support and funding by Public Works Government Services Canada, particularly Carol Beale and Craig Boyle; and from Natural Resources Canada, due to Anne Auger, Jim Clark, Pierre Guevrémont and Stephen Pope.

The Royal Architectural Institute of Canada has been a supporter and ally throughout the birth of the Canada Green Building Council, and creation of LEED Canada-NC 1.0. Our sincere thanks to Bonnie Maples and Christopher T. Fillingham.

The Canada Green Building Council exists today largely because of the early support and nurturing by our Founding Sponsors. Particular thanks are due to Ledcor Construction (Bronze Sponsor), and especially Johnson Controls LP (Platinum Sponsor).

The LEED Canada rating system leans heavily on the work done previously for LEED BC by Dr. Ray Cole and the LEED BC Steering Committee, who pioneered the fi rst adaptation of LEED for use outside the USA. The LEED BC Steering Committee generously made all of their work available to CaGBC in order to facilitate and accelerate the development of LEED Canada. At the time, the following individuals and organizations on the LEED BC Steering Committee contributed to the adaptation of LEED for use in BC: • Martine Desbois, BC Ministry of Competition, Science & Enterprise• Norm Connolly, CMHC • Alan Dobie, CMHC• Elizabeth Johnston, BC Hydro• Toby Lau, BC Hydro• Orest Maslany, BC Buildings Corporation• Kal Minhas, Terasen Gas• Thomas Mueller, Greater Vancouver Regional District• Ian Smith, City of Vancouver

We would also like to acknowledge Natural Resources Canada for its contribution to the energy equivalency work required to adapt LEED to BC.

Without the help and support of these dedicated volunteers and agencies, this document would not exist.

About the Canada Green Building CouncilThe buildings that we live in, work from and enjoy in our leisure activities represent the some of the largest human contributions to environmental impacts and resource depletion that threaten our environmental, economic and social sustainability. Designing, constructing and operating our built shelter in harmony with the natural environment can and must be accomplished. For humanity to have a future we must learn to live within the fl ows of nature and we must reduce the wastes and pollution


from our activities to levels that can be accommodated by the earth’s natural systems. It is to this future the Canada Green Building Council (CaGBC) is committed.

CaGBC Vision

“A transformed built environment leading to a sustainable future.”

CaGBC Mission

“Achieve the social, environmental and economic goals implicit in the vision by engaging a national coalition of industry leaders who create buildings and communities that are environmentally responsible, profi table, and healthy places to live, work and play. Promote and accelerate the mainstream adoption of green building awareness, principles, education, policies, practices, standards and tools.”

The Canada Green Building Council is a not-for-profi t Corporation established under the Canada Corporations Act, with Letters Patent issued December 5, 2002. The CaGBC was founded by a broad-based coalition that includes leaders from all major segments of the building design and construction industry. These include• Architectural fi rms• Commissioning providers• Controls contractors and manufacturers• Building owners, managers, occupants and brokers• Contractors and builders• Energy utilities• Engineering fi rms• Environmental groups• Financial and insurance fi rms• Municipal, provincial and federal government agencies• Manufacturers• Planners• Press• Professional societies• Property managers and operators• Real estate developers and agents• Specialist consultants• Universities, research institutions and community colleges

The CaGBC operates with a small paid staff in Ottawa and Victoria, and relies on the time, commitment, dedication and passion of its members and elected Board to advance its aims and achieve its objectives. The Council works to:• change industry standards,• develop best design practices and guidelines;• advocate for green buildings, and • develop educational tools to support its members in implementing sustainable

design and construction practices.


Member-Driven

The CaGBCs membership is open and balanced, and provides a platform for carrying important programs and activities. We target the issues identifi ed by our members as the highest priority. We conduct an annual survey of achievements that allows us to set policy, revise strategies and devise work plans based on members needs.

IntroductionIntroduction

Green Building Design

Green building design strives to balance environmental responsibility, resource effi ciency, occupant comfort and well-being, community development and the economics of building construction and operation. It includes all players in an integrated development process, from the design team (building owners, architects, engineers and consultants), the construction team (materials manufacturers, contractors and waste haulers), maintenance staff, and building occupants. This process results in a high-quality product that maximizes the owner’s return on investment.

Benefi ts of Green Building

Green buildings are far superior to their conventional counterparts, typically including features such as:

• Siting to minimise stress on natural systems, either by building on previously contaminated sites or by protecting ecologically-sensitive areas.

• Durable, thermally effi cient roofs, walls and windows that reduce heating and cooling and enhance thermal comfort.

• Building form, orientation and thermal mass optimized for solar gains, natural ventilation and daylighting for free heating, cooling, ventilation and lighting.

• Signifi cantly smaller and more effi cient HVAC and electrical lighting systems.

• Water effi cient supply and waste fi xtures.

• Adaptable interior designs, providing visual access to the outdoors and access to daylight.

• Interior fi nishes and installation methods having lower toxic emissions.

• Landscaping that requires little or no irrigation or application of synthetic chemicals, manages and treats stormwater and non-point-source pollution onsite, and replenishes groundwater supplies.

• Supports effi cient travel options for building users.

Over their lifecycles, green buildings use less energy and water, generate less greenhouse gases and other pollutants, use materials wisely, and produce less waste. They cost less to operate; are more adaptable to new uses and typically have longer economic lives. Occupants are more comfortable in green buildings with their excellent ventilation, thermal comfort, and abundant natural light. Green buildings are healthier for occupants and workers who process building materials, by minimizing use of materials made with harmful chemicals and indoor air pollutants, and reducing the likelihood of biological contaminants, such as moulds. By providing restorative views, plentiful outdoor air, and greater personal control of internal conditions, occupants’ lives and satisfaction are enhanced. Providing healthy indoor environments reduces sick building syndrome, and the risks of potential litigation. A growing body of research links the high quality indoor environments of green buildings to gains in productivity, decreased absenteeism and improved employee morale. Green design has environmental, economic, and social benefi ts for all stakeholders, including owners,


occupants and the general public. They are essential to support sustainable patterns of living.

LEED Canada-NC 1.0 for New

Construction and Major Retrofi ts

Increased awareness and interest in the environmental and health impacts of buildings in Canada has lead to widespread demand for a common method of certifying the merits of a given building – a well-understood way to ensure the building has met a rigorous and carefully defi ned level of environmental performance.

In response to this demand, the Canada Green Building Council was formed by members drawn from all segments of the Canadian building industry. They share the common goal of transforming the market toward more environmentally-sound shelter, by developing and delivering rigorous Canadian green rating systems. The aim has been to create rating tools that both recognize high health, energy and environmental performance, and are practical and easy to apply in real building projects.

LEED® Canada for New Construction and Major Renovations version 1.0 is an adaptation of the US Green Building Council’s (USGBC) Leadership in Energy and Environmental Design Green Building Rating System (LEEDR), tailored specifi cally for Canadian climates, construction practices and regulations. This fi rst version of LEED Canada has been adapted from the USGBCs LEED-NC 2.1 and infl uenced by anticipated changes planned for version 2.2.

LEED Rating Systems award points earned by meeting specifi c performance criteria that outperform typical standard practice defi ned in Prerequisites and Credits. Improved building performance

is certifi ed with ratings - Certifi ed, Silver, Gold or Platinum - based on the total number of points earned by a project. Building occupants, purchasers and lessors are assured of superior building performance by an independent review and audit of the projects’ construction documents by experienced design professionals that follow a well-defi ned and transparent methodology.

The LEED Canada-NC 1.0 adaptation leans heavily on the work done previously for LEED BC by Dr. Ray Cole and the ad-hoc LEED BC Steering Committee, who pioneered this fi rst adaptation of LEED for use outside the USA, which was approved by the USGBC in the summer of 2003. The LEED BC Steering Committee generously made all of their work available to CaGBC in order to facilitate and speed the development of LEED Canada-NC 1.0.

Adaptation of the USGBCs LEED-NC 2.1 to the new LEED Canada-NC 1.0 was lead by Dr. Raymond Cole and Stephen Carpenter, P.Eng. and Ian Theaker, P.Eng., with guidance by the CaGBCs LEED Steering Committee and Technical Advisory Group, and input from the Multi-Unit Residential Building Task Force (MURB Task Force). The LEED Canada-NC 1.0 Rating System was closely reviewed by the USGBC to maintain the rigour of and equivalence to its LEED-NC v2.1 counterpart; having addressed the USGBCs comments, it was then endorsed by a ballot of the CaGBC membership.

Drafts of the LEED Canada-NC 1.0 were reviewed by the CaGBC’s LEED Steering Committee, Technical Advisory Group, and design professionals, practitioners, developers and builders selected for their particular expertise and experience with conventional and


green building development in Canada and the US.

The number of unpaid volunteer hours in developing this Canadian rating system cannot be counted; it is truly a joint effort by many concerned, active design professionals, researchers, building scientists, builders and developers. The Acknowledgements page lists many of the key contributors and reviewers.

Applicability

LEED Canada-NC version 1.0 is designed to assess the performance of commercial and institutional buildings, i.e., buildings regulated by Part 3 of the National Building Code (NBC). LEED Canada-NC 1.0 can also be applied to many other building types, including retail, mid- and high-rise residential buildings, public assembly buildings, etc. However, users should be aware that, like LEED-NC 2.1, it was primarily developed with commercial offi ce buildings in mind, and can in some cases is less than well suited for more specialized building types.

The Canada Green Building Council intends to follow the lead of the USGBC, with future releases of Adaptation Guides for specifi c building types that assist users with their particular issues. The fi rst new Canadian Application Guide is likely to address the specifi c opportunities and constraints of mid- and high-rise multi-unit residential buildings.

Specifi cally, LEED Canada-NC applies to buildings regulated by the Model National Energy Code for Buildings (MNECB) Appendix E, section E-1.1.2.1.(2), as does Natural Resources Canada’s Commercial Buildings Incentives Program (CBIP). All three documents are intended to apply to the following building types:1. buildings more than three storeys in

building height,2. buildings of three storeys or less in

building height having a building area of more than 600m²,

3. buildings of three storeys or less in building height that contain occupancies other than dwelling units.

Multi-unit residential buildings (MURB) project are eligible, if they

1. are greater than 3 storeys in building height (i.e., 4 storeys or more), or be greater than 600m² in building area (footprint), as defi ned in the MNECB; and

2. have a common entrance.

New additions to existing buildings are eligible for LEED certifi cation. New additions are treated as a stand-alone project, separate from the existing building. The Sustainable Sites section has several clarifi cations on how individual buildings on a campus are to be treated. These rules apply equally to additions (as a stand-alone project) within the larger site.

LEED Canada-NC 1.0, the MNECB and CBIP do not apply to buildings regulated under Part 9 of the National Building Code, such as single-family houses (regardless of fl oor area) or townhouses. Eligibility of townhouses that are a part of mixed-use projects in which the majority of the fl oor area is eligible for LEED Canada certifi cation will be considered on their merits, considering installation of common HVAC and electrical systems and other environmental design features. However, applicants should be aware that this building type is specifi cally excluded from CBIP incentives; energy analyses conducted for EAp2, EAc1 and EAc2 should break out energy components for any areas not eligible for CBIP incentives.)


The introduction of LEED Canada-NC 1.0 provides the fi rst adaptation of the USGBC’s LEED-rating system to the Canadian context. However, as a broad guide, it necessarily refers to national and international standards and codes; local and regional requirements may be more stringent than those referenced in LEED Canada. Project design professionals and builders must still ensure that regional standards and codes are met or exceeded; this responsibility is not superceded by use of LEED Canada.

Structure of the LEED Canada-

NC 1.0 Rating System

LEED Canada-NC 1.0 includes the full range of Prerequisites and Credits included in the USGBCs LEED-NC v2.1, adapted to address issues, standards, resources and practices specifi c to Canada. In some instances, signifi cant changes have been made that are deemed to be more appropriate while still maintaining the intentions and rigour of LEED-NC v2.1. As well, LEED Canada-NC 1.0 includes a new addition to the Materials and Resources category, with Credit 8 - Durable Buildings. Table 1 at the end of this section highlights differences between LEED Canada-NC 1.0 and the USB’s LEED-NC v2.1.

Additional information related to LEED certifi cation is included within this LEED Canada Reference Guide. The Prerequisites and Credits are organized in the fi ve principal LEED categories:

• Sustainable Sites• Water Effi ciency• Energy and Atmosphere• Materials and Resources• Indoor Environmental Quality

An additional category, Innovation & Design Process, addresses expertise in

green design and construction, as well as design measures not covered under these fi ve environmental categories.

Prerequisites and Credits

Prerequisites and Credits are the core of LEED rating systems, and defi ne performance requirements that must be met to be eligible for certifi cation:

• Prerequisite requirements defi ne the minimum performance in a particular category that must be met by all projects applying for certifi cation.

• Performing the requirements of a Prerequisite does not contribute to a project’s point score; but is the minimal requirement that allows points to be earned from meeting or exceeding Credit criteria.

• All Prerequisite requirements must be met for a project to receive LEED Canada-NC 1.0 certifi cation.

• Credits are the fundamental method of defi ning LEED criteria that describe exemplary performance, and corresponding point awards, for a particular design or construction issue.

• Documented performance of the criteria outlined in each Credit is rewarded by a number of points that contribute to the overall rating for the project. Credits and available points in each performance category are shown in Table 2.

• A Credit can consist of several “Sub-Credits”, each of which adds further criteria that, with documented performance, may be rewarded with additional points.

• Application of any particular Credit is at the discretion of the project’s design and construction team, responding to its unique constraints and opportunities.


Points are earned by fulfi lling the requirements laid out in each Credit; the total number of points awarded in all Credits and categories determines an overall rating of Platinum, Gold, Silver or Certifi ed for a project. Project ratings are certifi ed by the CaGBC based on the total point score, following an independent review and audits of documentation submitted by a design and construction team. With four possible levels of certifi cation, LEED is fl exible enough to accommodate a wide range of green building strategies that best fi t the constraints and goals of particular projects.

While Credit descriptions and requirements are by necessity specifi c, the critical issue with the use of LEED is meeting the intent of the credit, and documenting equivalent or better performance to the Requirements defi ned to meet that intent.

LEED Reference Guide

The Reference Guide is the user’s manual for LEED-Canada, intended to assist project teams in understanding and applying LEED criteria. The Guide includes examples of strategies found to be effective and practical, case studies of buildings that have implemented these strategies successfully, and links to other resources. The Guide does not pretend to provide an exhaustive list of all strategies that may meet a particular

Prerequisites’ or Credits’ intent, nor does it provide all of the information that design teams may need to apply a particular strategy well in a particular project. Designers, builders and developers are encouraged to combine the burgeoning body of emerging green design knowledge now widely available with their own professional judgment and experience.

Prerequisite and Credit Format

Each chapter in the Reference Guide is organized in a standardized format for simplicity and quick reference.

The fi rst section summarizes key points regarding the measure’s intent and requirements:

• Intent: The main goal of the Prerequisite or credit.

• Requirements: The criteria to satisfy the Prerequisite or Credit and the number of points available. The Prerequisites must be achieved. Each Credit is optional, but contributes to the project’s point total. Some Credits are divided into two or more Sub-Credits with independent or cumulative points.

• Submittals: The documentation required for an application for LEED certifi cation.

• Audited Credit Submittal Requirements: A summary of additional documentation required to be submitted for certifi cation review, should the Credit be audited. This is typically information necessary for the design and construction team to manage the development process, and ensure that performance objectives are met by the project.

• Summary of Referenced Standards: Many LEED Prerequisites and Credits refer to technical standards developed by other organizations

for performance evaluation. A brief summary of referenced standards are provided in this section; but users are strongly encouraged to closely review the original standards in detail, and not rely solely on summaries provided in the LEED Reference Manual.

• Interpretation: This section provides additional advice on meeting the Credit requirements based on Credit Interpretation Rulings (CIRS) provided for previous LEED versions.

The subsequent sections provide supportive information to help further interpret, implement, and document performance:

• Green Building Concerns: Outlines environmental, economic and community issues related to the Prerequisite or Credit.

• Design Approach: Ideas and suggestions for project design and specifi cations:

• Synergies & Trade-Offs: Other green design approaches or LEED Credits that are likely to affect or interact with design elements that address the particular Prerequisites’ or Credits’ intent. Users are advised to carefully understand possible interactions between related approaches, and evaluate their application in light of the unique conditions of their particular project.

• Calculations: Sample formulas or calculations are provided that illustrate how to determine performance for a particular prerequisite or credit. Some calculations have been programmed into the LEED Canada-NC 1.0 Letter Template spreadsheet provided to registered LEED Canada projects to assist in documenting and demonstrating performance in certifi cation applications.

• Resources: Key websites and documents – both general and regional – that assist the design team in meeting the Credit requirements.

• Defi nitions: Defi nitions of the key terms referenced within the credit.

• Regional Variations: Additional commentary related to handling possible regional differences.

• Case Studies: Examples that illustrate how a project has met the intent and requirements stated for the prerequisite or credit. The selected project exemplifi es one method to achieve the intent of the measure.

LEED Certifi cation Process

Application

Consult the CaGBC website for important details about application of LEED Canada, as well as the certifi cation review process, schedule and fees and other information not included in this Reference Guide. The LEED website home page can be found at www.cagbc.org.

LEED Canada Project Registration

The fi rst step toward LEED certifi cation is registering the project with the Canada Green Building Council. Registering early in the development process ensures the maximum potential for high building performance, and establishes contact with the CaGBC. LEED Canada-NC 1.0 registration of a LEED Canada project provides online access to essential information, software tools and communications for LEED users, and allows the team to submit Credit Interpretation Requests (CIRs) to the CaGBC. Two Credit Interpretation Requests for each registered project are included in the registration fee; additional Credit Interpretation


Requests are available for a nominal fee that covers CaGBC costs.Project leaders wanting to register under LEED Canada NC v1.0 should use the Canada Green Building Council website <http://www.cagbc.org/> to:

1. Review the contents of the Costs for Registration and Certifi cation menu item.

2. Review the contents of the Certifi cation Process, and

3. Fill out the online form, and submit it to the CaGBC.

The registration form may take up to 30 minutes to complete. Registrants will be asked for project data available at early stages of the development process:

• Contact information for key project people

• General project information: title, occupancy date, address, etc.

• A brief Project Description

Information supplied on the registration form will be used by the CaGBC for project tracking, answering Credit Interpretation Requests, and preparing project case studies upon certifi cation.

Documentation

Once a project is registered, the typical project team proceeds with the design and construction process, collecting and preparing documentation as their process unfolds to ensure the building meets its environmental, energy and health performance objectives, and in formats that satisfy LEED Canada Prerequisite and Credit submittal requirements. Using the LEED Checklist regularly at coordination meetings, and preparing LEED submittals as design and construction progresses makes the task of LEED documentation much easier.

Attempting to complete LEED project submittals after the fact has typically proved to be diffi cult and expensive, and often results in incomplete submittals that delay certifi cation or result in denied point awards and a lower rating.Once submitted to the CaGBC, this documentation becomes the proof behind performance declarations made in the LEED certifi cation application. In many projects, a LEED Accredited Professional is designated as the project contact and team member responsible for coordinating the certifi cation process.

The LEED Letter Template is a dynamic tracking and documentation tool used by registered project teams to track progress and prepare its application for LEED certifi cation. For each Prerequisite and Credit, the Letter Template prompts LEED practitioners for summary data, indicates when documentation requirements have been adequately fulfi lled for submittal, serves as a template for signed declarations of performance, and summarizes progress. Some Template tabs include detailed spreadsheet calculations and required data, while others are simple declarations to be printed on the fi rm’s letterhead and signed by an appropriate team member. The Letter Template’s spreadsheets are particularly useful when the Reference Guide calls for specifi c calculations to document Credit performance.

It is important to have a thorough understanding of each Credits unique requirements, and to submit only the documentation required to clearly demonstrate these requirements have been met. Including extra documentation not listed as a submittal requirement for a Prerequisite or Credit is discouraged, as this can slow the review process. Full building commissioning reports, for example, are not necessary with an initial


application; only the commissioning plan is required.

One item is of major importance in the initial submittal: the overall project narrative. Not only is this the fi rst item reviewed in certifi cation applications, it is very likely to be used in CaGBC promotional materials aimed at the general public. As such, these narratives should clearly and briefl y summarize all health, performance and environmental features of the project, preferably addressing each LEED Prerequisite and Credit. Graphics, charts and photos supplementing the summary text for features with particular merit or complexity often adds clarity for reviewers and interest for the general reader.

Uses of Documentation Submitted

& Intellectual Property Protection

The CaGBC is mindful of the privacy of certifi cation applicants, and conscious that submitted materials are the intellectual property of their creators. As agreed in the project registration process, some submitted materials are used by the CaGBC to promote the project and its merits to the general public; and may be used by the CaGBC in training or marketing activities, or in aggregated form to expand the growing knowledge base of green building technique, costs and trends. Information likely to be widely shared includes:

• LEED registration information, such as project contact, project type, fl oor area, number of occupants, date of construction completion, etc.;

• the overall project narrative; • colour photographs or renderings

illustrative of the project; and • the LEED Project Checklist/

Scorecard

All other documents and materials submitted to the CaGBC are kept in strict confi dence, and will not be distributed beyond those directly involved in certifi cation, interpretations or appeals procedures, such as CaGBC staff, Technical Advisory Group or LEED Steering Committee members, and designated reviewers who have signed a confi dentiality agreement. Any additional distribution of submitted materials, if any, would occur only after the CaGBC has requested and received prior written permission from owners of the relevant intellectual property.

Certifi cation Application and

Review Process

The project certifi cation process follows several steps:

1. The initial application for certifi cation is submitted to the CaGBC, along with required documentation outlined in the Reference Guide and Letter Template. Other supporting information should not be submitted at this stage; if a Prerequisite or Credit is audited, additional information for specifi c Credits will be requested.

2. The LEED Program Manager reviews applications for suitability and completeness. Applications missing any template or submittal item listed in the Reference Guide and the Letter Template are returned to applicants to fi ll gaps and allow certifi cation review to proceed effi ciently.

3. With a complete application for certifi cation, the review team performs a Draft Preliminary Review which assesses submitted documentation to determine if the intent and requirements have been met for all pursued Prerequisites and Credits (P&Cs). The Draft Preliminary Review classifi es each P&C as ‘Credit


Achievement Anticipated’ (‘CAA’), ‘Pending’ or ‘Denied’:

• ‘Credit Achievement Anticipated’ indicates that the project applicant has provided documentation supporting a claim of achievement. ‘CAA’ P&Cs may be audited to ensure the project applicant can demonstrate their claim of P&C achievement.

• ‘Pending’ indicates that the submittals received do not allow a clear assessment that the P&Cs intent and/or requirements have been fully achieved. Supplemental information supporting ‘Pending’ P&Cs is requested from applicants to evaluate and resolve questions or discrepancies, before being classifi ed as ‘CAA’ or ‘Denied’.

• ‘Denied’ indicates that the documentation submitted demonstrates that the P&C intent has not been achieved or was not attempted. ‘Denied’ P&Cs are not reviewed further.

Reviewers provide a rationale for the classifi cation of each P&C, including requests for supplementary documentation for ‘pending’ P&Cs. In addition, the review team selects six P&Cs for audit; detailed supporting documentation is requested from the applicant for each. Documentation to be submitted for audited P&Cs is outlined in the Reference Guide and Letter Template spreadsheet. (Note that EAc1 will always be audited.)

4. CaGBC staff performs a quality assurance check of the Draft Preliminary Review, and discusses edits and changes with the review team leader before their completion of the Preliminary LEED Review.

5. The Preliminary LEED Review is

forwarded to the project applicant, who replies to the LEED Program Manager with the supplemental documentation requested for ‘Pending’ and audited ‘CAA’ P&Cs. This documentation is forwarded to the review team.

6. The review team assesses supplemental documentation received from the applicant, and develops a Draft Final LEED Review. The Final LEED Review indicates P&Cs that are ‘achieved’ or ‘denied’, and provides a rationale for the designation of each. If the documentation provided in support of audited P&Cs is acceptable, ‘CAA’-designated P&Cs are deemed ‘achieved’; otherwise they are deemed ‘Denied’.

7. CaGBC staff conducts a quality assurance check of the Draft Final Review, and the review team revises the Draft Final Review as directed to arrive at the Final LEED Review.

8. If one or more audited Credits are denied in Step 7, the project has failed the audit. The review team may select up to six additional unaudited P&Cs designated as ‘CAA’ in the Preliminary LEED Review for a second audit. They then prepare a Second LEED Review which lists new P&Cs to be audited, and begins the audit process detailed in Steps 2-7 again. Auditing shall continue until the project applicant successfully completes an audit, or until all ‘CAA’ P&Cs have been audited.

9. Upon completion of all audits, the CaGBC will forward the Final LEED Review to the project applicant. Project applicants then have the opportunity to appeal “Denied” P&Cs by providing additional documentary evidence of performance of the applicable intent and requirements.


This additional documentation is reviewed both by the original review team and by the CaGBC. Appeals are levied a nominal fee that covers CaGBC costs.

10.When the appeal process (if any) is concluded, the Canada Green Building Council awards an offi cial rating of Certifi ed, Silver, Gold or Platinum, or a notifi cation that the project did not achieve any LEED rating, depending on the performance of the building. If a rating is awarded, a plaque and an offi cial letter certifying the project’s performance is sent to the applicant, and press releases and promotional materials are prepared and distributed by the CaGBC.

Credit Interpretations

In some cases, project teams may encounter diffi culties applying a LEED Prerequisite or Credit to a specifi c project. Questions sometimes arise when the Reference Guide does not suffi ciently address a specifi c issue, or there is a special confl ict that requires resolution.

CaGBC has established a standard process to provide interpretations to registered project teams, called Credit Interpretation Requests (CIRs), to ensure that rulings are consistent, available to other projects, and to guide future revisions to the Rating System, Reference Guide and Letter Template. Inquiries must request guidance on a single Credit or Prerequisite (unless there is technical justifi cation to do otherwise) per CIR, which generally contain one concise question, or a set of closely-related questions. It is often helpful to discuss the inquiry within context of the credit’s intent.

USGBC credit rulings are not applicable to LEED Canada projects. The LEED Canada-NC 1.0 rating system and

Reference Guide has addressed previous USGBC credit interpretation rulings; and subsequent USGBC rulings are regularly reviewed by the CaGBC, and those applicable to LEED Canada projects are adapted to the Canadian context, and published on the CaGBC website.

Credits are not awarded through the CIR process, and the process is not intended to add new Credits. The CIR process is designed to provide feedback to the project applicant on the likely outcome of a proposed strategy that addresses a particular Prerequisite or Credit’s intent. Credit Interpretation Rulings do not guarantee a credit award; the project applicant must still demonstrate and document achievement during the LEED Certifi cation Application Process.

Credit language or achievement thresholds cannot be changed through the CIR process. If a project applicant submits a Credit Interpretation Request that poses a broad reaching policy issue that cannot be readily addressed by the LEED Technical Advisory Group, the Council may circulate the interpretation request to the LEED Steering Committee and/or relevant CaGBC Committees as required. The timeline for response to such inquiries may, of necessity, be extended to afford the required time to address the issue commensurate with its complexity. Project applicants will be notifi ed if the CIR submitted falls into this category as soon as possible.

Credit Interpretation Requests and rulings received from the CaGBC must be submitted with the LEED initial application in order to ensure effective certifi cation review.

If a question requiring CaGBC interpretation arises, project teams should:

1. Review the intent of the credit or prerequisite in question and evaluate whether the project meets this intent.


2. Consult the Reference Guide for more detailed explanation, instructions, calculations and guidance.

3. Review the CaGBCs Credit Interpretation Request (CIR) Web page <www.cagbc.org> for previously logged CIRs issued for the particular Prerequisite or Credit. All registered LEED project contacts and members have access to this page.

4. If a similar Credit Interpretation has not already been logged, or does not adequately resolve the issue, submit a Credit Interpretation Request using the online form found at the CaGBC website. The inquiry should be clear, succinct and based on information found in the Reference Guide, emphasizing how the proposed solution meets the intent of the Prerequisite or Credit, and provides equivalent performance to its requirements. Include concise background and/or supporting information, providing relevant project details only; do not include a lengthy project narrative, as it will most likely include information outside the scope of the specifi c CIR.

CIRs should include:• the number and title of the Prerequisite

or Credit, and its intent statement

• a brief summary of the issue at hand and essential background information

• if an alternative solution to those identifi ed by the Prerequisites’ or Credits’ requirement is proposed, provide details of how the proposed solution meets or exceeds the performance of the requirement listed in the Guide, and how this can be satisfactorily documented.

Do not include confi dential project details; the submitted text will be posted on the CaGBC Web site.

Please proofread your text for clarity, readability, spelling and grammar.

• include a copy of any interpretations received from the CaGBC in the initial certifi cation submittal.

Initial Project Certifi cation Appli-

cation

In the initial application for project certifi cation, the project team submits two identical binders, each with ALL project materials listed below. These should be accompanied by a cheque for the appropriate certifi cation fee payable to the Canada Green Building Council. All certifi cation submittals should be sent to:

Canada Green Building Council, Victoria offi ceVancouver Island Technology Park4464 Markham St., Suite 2103 DVictoria, BC V8Z 7X8CanadaAttention: LEED Program Manager

Each three-ring binder submitted for the initial application for certifi cation should include:

• a binder cover page and spine that shows the project name, the date of certifi cation submittal, and the version of LEED for which the certifi cation application is being made (e.g., “LEED Canada-NC 1.0 Certifi cation Application”);

• introductory pages with LEED registration information, including the project contact, project type, project fl oor area, number of occupants, date of construction completion, etc.;

• the LEED Project Checklist/Scorecard indicating anticipated Prerequisites and Credits point awards, and the total rating score for the project;


• an overall project narrative that summarizes all project features that respond to health and environmental priorities (and each Prerequisite and Credit), including at least three highlighted features of particular interest to CaGBC reviewers, and potential purchasers, lessors or building occupants, suitable for reading by the general public;

• colour photographs or renderings illustrative of the project, including building elevations and the primary entrance to the building, in letter, legal or 11”x17” format;

• drawings illustrative of the project in letter, legal or 11”x17” format, including:- site, context and landscaping plans

- typical fl oor plans, building sections and elevations

- schematic diagrams of major electrical and mechanical systems

- window, lighting and HVAC equipment schedules and tables

- hardcopy submittals required by this Reference Manual and the Letter Template, for each Prerequisite and Credit, such as signed declarations of performance, letters, summary data, calculations, reports, a copy of any Credit Interpretations received from the CaGBC by the project, etc., separated by labeled index tabs;

- a CD containing the completed Letter Template spreadsheet.

Audits

For audited Prerequisites and Credits, applicants are expected to provide detailed supporting documentation that back up claims made in letters declaring achieved performance. In this Reference

Guide, the Submittals sections in each Prerequisite or Credit lists specifi c documentation applicants are expected to submit for audited Prerequisites and Credits. These may include calculations, specifi cations and drawings, cut sheets, manufacturer’s literature, and/or other source documents that document in detail performance claims made in the Letter Template.

Users have found that preparing LEED submittals as design and construction progresses can be an excellent management tool, and makes the task of LEED documentation much easier.

Supplements to LEED Canada

for New Construction and Major

Renovations

LEED Canada-NC 1.0 is intended to refl ect the national Canadian context in design and construction of commercial and institutional buildings. However, some organizations, such as provinces, municipalities, or property management fi rms and institutions may wish to create Supplements offi cially recognized by the CaGBC, and bearing the LEED Canada trademark that:

• identify additional mandatory requirements or specifi c levels of performance to be attained by projects in their portfolios,

• provide a common rationale that demonstrates equivalent or better performance for specifi c LEED Canada requirements, eliminating the need for individual submissions by each project under their purview, or

• adapt LEED Canada requirements to suit other needs specifi c to their own goals.

Organizations considering preparing and administering an offi cial Supplement to


LEED Canada-NC 1.0 are advised to contact the LEED Program Manager early in the process to discuss copyright issues, coordinate efforts to ensure consistency across all LEED Rating Systems, and minimize confusion by users and the general public with the LEED Canada Rating System. .The USGBC has developed specifi c guidelines for such supplements, which are applicable to Canadian efforts.

LEED Canada as a Design

ToolThe LEED Canada rating system helps identify effective ways to address the health, resource and environmental issues of building design and construction. One of its most goals is to encourage and assist architects, engineers, builders and developers to develop improved standards of practice and performance.

LEED Prerequisites and Credits derive from expert committees in each performance category. The committees, composed of industry, environmental and private and public sector representatives, are charged with defi ning and framing the content of Prerequisites and Credits, and defi ning appropriate point awards. A host of theoretical, practical and cost-related issues shape the fi nal performance targets demanded, such as:

• What environmental issues should be included? What should be left out?

• Should lower priority issues be included at the expense of simplicity and ease of implementation and use?

• How can qualitative performance in environmental or health issues be defi ned clearly and unambiguously?

• What is the simplest quantitative

method to measure performance toward a stated intent that applicants can easily provide?

Draft LEED Rating Systems are balloted prior to their public launch, and supplemental Reference Guides and supporting materials are reviewed by industry experts as well as the CaGBC. However, while the fi nal outcome represents one level of industry consensus; many other important green building considerations are absent in currently-available environmental rating systems, including LEED.

An environmental rating system will often be used as a design “tool” even if it was not specifi cally designed for that purpose. Since rating systems present an organized set of selected environmental criteria, they implicitly communicate to building owners and design teams their authors’ assessment of the most signifi cant environmental issues. However, there is concern that the details of environmental rating systems may drive the product and process, i.e., achieving a high LEED score may be deemed by the design team to be more important than aspiring to excellent overall performance, and detract from a more fundamental professional commitment to environmental responsibility.

In addition to the number and type of environmental issues addressed, two important issues of using a rating system more broadly to guide design and construction efforts are:

• Understanding the possible and achievable ranges of performance, in particular benchmarks of typical mainstream practice and realistic targets for improvements.

• Understanding how different health and environmental issues are linked,


and the best phases and actors in the design and construction process to address them well.

Benchmarks and Targets

All environmental rating systems implicitly embody a scale of performance measurement. In LEED, such a scale forms the basis for allocating points that contribute to an overall performance rating.

• Benchmarks: LEED Canada assesses the improvement in environmental performance by assigning points when a particular level of performance has been met. Although not explicitly stated, the baseline for assessment is a ‘typical’ or ‘mainstream” performance and, as such, recognition is given for performance that betters current industry norms.

Some of the LEED Canada Credits have benchmarks that are explicitly declared. EAc1, for example, assigns an increasing number of points for building performance improvements relative to the requirements of Natural Resources Canada’s Commercial Building Incentive Program, which are based on the 1997 Model National Energy Code for Buildings (MNECB).

• Targets: To create an assessment scale and assign scores, demanding “targets” are required to defi ne excellent project performance. In LEED Canada, performance excellence is refl ected by the maximum number of points that can be achieved within a given Credit.

Many of the highest LEED Canada performance targets are considerably in advance of current mainstream practice, and will challenge many design and construction teams to meet them. However, as knowledge of “green” design and construction matures and is applied more widely, new, more effective responses will become standard mainstream practice.

As this occurs, performance targets will progressively evolve in future versions of LEED-Canada, until they result in mainstream practice that creates truly “sustainable” shelter.

Design Process

& Responsibilities

An important indirect benefi t of using LEED during the design process is that the broad range of issues covered requires broad communication and interaction between members of the design team and various actors in the design process, i.e., environmental rating systems encourage greater dialogue and teamwork, especially in program development and schematic design.

A wider range of players – clients, occupants, design architects, engineers and specialist consultants, contractors and maintenance staff – are often involved in different degrees in exploring and developing strategies that lead to the successful achievement of LEED requirements.

Table 3 shows the LEED Canada Prerequisites and Credits organized within these fi ve phases:• Pre-design• Conceptual Design/ Design Development• Construction• Use/Operation• Decommissioning

Although design decisions have profound implications through the life of a building, the notations shown in Table 3 identify when strategic choices are made or actions taken with the most infl uence on the implementation of design responses to Prerequisites and Credits, and the primary and other responsible people.
