New Construction

The LEED® Canada NC rating system applies to new construction and major renovations of commercial and institutional buildings, i.e., buildings regulated by Part 3 of the National Building Code. It also applies to retail, mid- and high-rise multi-unit residential buildings (MURBs), public assembly buildings, manufacturing plants, and other types of buildings.

Applicants with space that is not fitted out at the time of certification (e.g., intended for future lease) may wish to consider LEED Canada for Core & Shell Development. Alternatively, those projects with at least 50% of the building fit-up for certification may use the leased tenant space guidance for NC projects found in the LEED Canada Reference Guide for Green Building Design and Construction 2009.

LEED Canada NC 2009

LEED Canada NC version 2009 provides many advantages over version 1.0, including:

  • Consolidation of documentation: all the Application Guides and relevant CIRs have been incorporated.
  • Updated reference standards: the new rating systems refer to more current reference standards.
  • New and updated pathways: several alternative credit compliance pathways have been introduced, and thresholds have been adjusted to better reflect the state of the industry.
  • Re-weighted credits: the number of points that may be earned for each credit has been re-evaluated using a more scientific approach, resulting in greater emphasis on preventing climate change.
  • Familiarity: the majority of credits have not substantially changed.
  • Faster certification: the audit round of the certification process has been eliminated, and streamlined compliance pathways are available for some credits.

LEED Canada NC 1.0 projects are welcome to switch to the new rating system.

Registration for this rating system will close on October 31, 2016. After this date, projects must register under LEED v4.

Rating System and Reference Guide

LEED Canada NC 2009 and LEED Canada CS 2009 Rating System - released June 21, 2010 - outlines credit requirements and provides a credit checklist.

LEED Canada Reference Guide for Green Building Design and Construction 2009 (online purchase - if you have already purchased the Reference Guide in electronic format it is available in the My Documents section of My CaGBC) - a detailed outline of the credits that may be utilized for LEED Canada NC 2009 registered projects. Strategies and additional resources are included to help in meeting the requirements of each credit and prerequisite.

Introduction Section of the LEED Canada Reference Guide for Green Building Design and Construction 2009 – publically available excerpt to assist project teams in selecting the appropriate LEED rating system.

Minimum Program Requirements

Minimum Program Requirements (MPRs) for LEED Canada Rating Systems (pdf) – The MPRs list the basic characteristics that a project must possess to be eligible for certification under the LEED Canada rating systems, therefore defining a broad category of buildings and spaces that the LEED Canada rating systems were designed to evaluate. These MPRs replace those found in the LEED Canada Reference Guide for Green Building Design and Construction 2009 for all LEED Canada NC projects registered on or after September 1, 2012. All projects required to follow the MPRs must provide a signed MPR form with their project submission, declaring the project meets all MPRs or allowed exceptions.

Minimum Program Requirements Declaration Form (xls) – This form is a requirement on all LEED Canada NC 2009 projects.

Project Resources

The following documents and tools are critical to any project pursuing LEED certification. These materials are copyright protected and may only be used on projects that are registered for LEED certification. In order to view the materials, you must be a Member and you must be logged in.

 LEED Canada NC and CS 2009 Letter Templates version G (xls) - support the required declarations for each of the prerequisites and credits under LEED Canada NC 2009 and LEED Canada CS 2009. Updated to resolve error with Innovative Wastewater Technologies, as well as other improvements. All projects registered after October 1st, 2016 are required to use this version; projects registered earlier are encouraged to use the latest version as well.

Portland Cement Reduction Calculator (xls) - provided in support of Materials and Resources credit 4 (Recycled Content). Version 2, July 2012. This document is not limited to CaGBC members. A Technical Bulletin explaining the proper use of the calculator may be found on the website of the Ready Mixed Concrete Association of Ontario.

CaGBC Durable Building Tables (xls) - provided in support of Regional Priority credit 1 (Durable Building).

LEED Canada NC and CS 2009 Project Checklist (xls) - helps project teams track their credits against requirements for certification.

LEED Canada 2009 Supplementary Energy Modelling Guidelines (pdf) - supplements and/or clarifies the energy modelling guidance provided for LEED Canada for New Construction and Major Renovations 2009 and LEED Canada for Core and Shell Development 2009 EA Prerequisite 2 and EA Credit 1, Option 1 – Whole Building Energy Simulation. Updated December 16, 2014

LEED Canada 2009 Interpretation Guide for District Energy Systems (pdf) – all projects registered on or after April 1st, 2012 must use this guidance document. LEED Canada NC/CS 2009 projects registered prior to this date may use either this new guidance or the Interpretation Guide for District Energy Systems (March 2008), published as part of the Application Guide for Campuses and Multiple Buildings. It is recommended that such projects adopt the new interpretation guide as it provides much clearer guidance overall. LEED Canada-NC/CS 1.0 projects may opt to use this new guidance for EAp2 and EAc1 only, the March 2008 document must be used for all other prerequisites and credits.

Guidance for Non-Traditional Fuels in LEED Canada (pdf) – this document provides guidance for EAp2 and EAc1 for LEED Canada projects that use Non-Traditional Fuels (NTFs) to provide heating, cooling, and/or electricity to buildings. Only projects registered prior to July 1, 2015 may use this guidance document. All projects registered on or after July 1, 2015 must follow CIR 1235 - How should purchased renewable energy and purchased biofuels be treated in the energy model.
