CANADA’S CBIP VERSUS THE UNITED STATES’ LEED™: BUILDING ENERGY PERFORMANCE PATH REQUIREMENTS

Curt Hepting, P. Eng

Abstract: LEED-Canada is launching a green building rating system based on the U.S. Leadership in Energy and Environmental Design (LEEDâ„¢) rating system. As part of the system, it assessed the energy performance difference between Canada's Model National Energy Code for Buildings (MNECB) and the ASHRAE/ IESNA Standard 90.1-1999 energy code (ASHRAE) to develop an equivalent localized rating system. A comprehensive review of the two energy standards and the development of dozens of DOE2 models were conducted to evaluate the differences. The models represented compliant reference cases for both respective standards for prototype building types and HVAC configurations across Canada. A comparison of the overall aggregate difference showed that ASHRAE is nearly 11% more stringent than the MNECB. This paper provides an overview of the approach followed to determine the relative differences between the codes, as well as summary results from the analysis.
