1.0 IntRoDUctIon
This resource is designed to assist municipalities to effectively construct and
develop high performance and LEED® certifed buildings.
In 2002, the Greater Vancouver Regional District (GVRD) Green Building Program
developed the LEED Implementation Guide for Municipal Green Buildings. This
guide has been successful in helping municipalities, consultants, and public sec-
tor building owners understand green building concepts and the LEED rating
system as it applies to new municipal facilities.
The GVRD Design Guide for Municipal LEED Buildings is more of a “how-to
guide” and Technology Series that places a greater emphasis on practical solu-
tions that will help municipalities in the GVRD achieve higher levels of perform-
ance and LEED certifcation. This Design Guide builds upon the previous guide
by providing:
• Up-to-date information on LEED in Canada;
• Municipally-based solutions to meet LEED credits;
• Guidelines on the ease of implementation, capital cost, and life-cycle cost;
• Operational feedback from built case studies;
• Practical solutions to meeting LEED credits;
• Barriers and issues of design solutions;
• Relevant resources; and
• The responsibilities of professionals.
In conjunction with this Guide, a series of Technology Fact Sheets has been
developed to provide municipalities with detailed information on specifc sus-
tainable technologies. These fact sheets are intended to promote market-ready,
sustainable technologies that are applicable throughout the Greater Vancouver
Region. The technologies include:
• Geo-exchange heating and cooling systems
• Waterless urinals
• Domestic solar hot water
• Daylighting
• Demand control ventilation
These fact sheets can also be used as stand-alone documents.

1.1 sUmmaRy of DesIgn solUtIons anD measURes
Each section presents a number of design solutions with guidelines on the ease
of implementation, capital cost, and life cycle cost. A complete summary of the
design solutions and information related to ease of implementation, capital cost,
and life cycle cost is provided below.
Defnitions of ease of Implementation
Easy: Off the shelf, readily available product or technology
Low–no risk
Many precedents of application in potential other geographic
areas, building types, or industries
Low–no user and maintenance training issues
Moderate: Low-moderate risk
Some training or user modifcation required
Changed or increased maintenance requirements
Some precedents of application in potential other geographic
areas, building types, or industries
Diffcult: Medium-high perception of risk
Use and maintenance training required
Few or no precedents of application in potential other geographic
areas, building types, or industries
Defnitions of capital cost
Capital Cost: Net project impact rather than individual strategy or product cost
Cost neutral: +/- 2% of conventional project
Moderate cost increase: 2% - 20%
High cost increase: 20% +
Cost savings: Overall cost savings
Defnitions of life-cycle cost
Immediate Payback: 0 - 5 year payback
Moderate Payback: 5 - 0 year payback
Long Payback: 0 years +

2.0 oVeRVIeW of tHe leeD® gReen bUIlDIng RatIng system
Since the inception in 998 of the LEED® (Leadership in Energy and Environmen-
tal Design) Green Building Rating System by the U.S. Green Building Council (US-
GBC), the Council is continuously in the process of updating the Rating System
and developing new application guides for different building types. The follow-
ing LEED Rating Systems are currently available in the U.S. marketplace:
• LEED-New Construction 2.2
• LEED-Existing Buildings
• LEED-Commerical Interiors
• LEED-Core and Shell
2.1 leeD In canaDa
Initially, LEED was solely based on accepted U.S. energy and environmental
standards to evaluate the environmental performance of a building over the
building’s life cycle. In 2003, the Canada Green Building Council (CaGBC) was
formed to represent the rapidly emerging Canadian green building industry. The
CaGBC launched its newly adapted LEED guidelines, LEED-Canada for New Con-
struction version .0 (LEED Canada-NC) in December 2004, under license from
the USGBC. These guidelines refect Canadian standards, guidelines and regula-
tions, and closely parallel the USGBC’s LEED-NC Rating System.
All Canadian LEED projects are now being registered and certifed exclusively
under the CaGBC. There are some signifcant changes in LEED Canada-NC that
projects should be aware of when pursuing LEED certifcation. Under LEED
Canada-NC there are now a possible 70 points rather than 69 points a project can
achieve; further information on these changes can be obtained from the CaGBC.
Appendix A provides a LEED Canada scorecard.
2.2 leeD canaDa maRket DeVeloPments
The Canada Green Building Council is also developing rating system products in
Canada to respond to various market needs. To date, the CaGBC has developed a
supplementary Application Guide for Multi-Unit Residential Buildings and LEED
for Commercial Interiors. The CaGBC is in the process of developing an Applica-
tion Guide for Campus and Multiple Building projects which will be available for
use in Canada by Fall 2006.

2.3 mUnIcIPalItIes anD leeD
Municipalities across Canada are leading the market in having new projects
certifed under the LEED Canada-NC system. The majority of the LEED certifed
projects in Canada are municipal projects; see the list below for examples of
these projects.
