Guidance and tools for the LEED v4 NECB 2011 ACP

Green Building Team on April 28, 2017

The CaGBC is pleased to provide new guidance and tools to assist Canadian projects wishing to use the National Energy Code for Buildings (NECB) 2011 for demonstrating energy performance under LEED v4. The following documents are now available on the website:

  • Minimum Energy Performance Calculator for NECB 2011 ACP
  • Multifamily Energy Model Simulation Guidelines for the NECB 2011 ACP

Minimum Energy Performance Calculator for NECB 2011 ACP

The Minimum Energy Performance Calculator for NECB 2011 ACP is an excel based tool to be used for projects documenting Minimum Energy Performance using the NECB ACP for LEED v4 BD+C and LEED v4 ID+C EA Prerequisite Minimum Energy Performance and EA Credit Optimize Energy Performance. This calculator contains required checks on energy model inputs, based upon the NECB 2011 ACP, as well as summary output totals. The summary tab in the calculator is used to complete the form in LEED Online. The beta version of the calculator is available for download on the LEED v4 Canadian ACPs page on the website. Project teams are asked to help with the ongoing improvement of the calculator by sending any feedback or comments on the tool to info@cagbc.org.

Multifamily Energy Model Simulation Guidelines for the NECB 2011 ACP

The CaGBC has adapted the USGBC’s Multifamily Energy Model Simulation Guidelines which were based on ASHRAE 90.1-2010 for use with the Canada ACP for NECB 2011. The Multifamily Energy Model Simulation Guidelines for Canada ACP – NECB 2011 are now available under the LEED v4 Canadian ACPs page on the website.

The Multifamily Energy Model Simulation Guidelines (ASHRAE 90.1-2010 or NECB 2011) are applicable to all multifamily residential projects pursuing the Whole-Building Energy Simulation path under LEED v4 BD+C: Multifamily Midrise as well as under LEED v4 BD+C.

Note that in October 2016, the USGBC released an addenda allowing high-rise residential buildings of 4 stories or more to use either the LEED v4 BD+C or the LEED v4 BD+C: Multifamily Midrise rating system.
