Inquiry

Use of Canada\'s MNECB for Budget Case Our project is a hospital addition in Sarnia, Ontario. With respect to this credit and EAp2 we would like to compare the proposed design to Canada\'s Model National Energy Code for Buildings (MNECB). According to the credit requirements, comparison against a local code may be used in lieu of ASHRAE Standard 90.1-1999 if, "a defensible equivalency (at minimum) to ASHRAE Standard 90.1-1999 has been established." A comparison of the MNECB with ASHRAE Standard 90.1-1999 was performed for the development of LEED-British Columbia (LEED-BC) and a compliance path based on the MNECB was accepted by the USGBC. This path has also been proposed in the LEED-Canada Draft, to be approved by the USGBC in the near future. We propose substantiating our compliance with EAc1 and EAp2 by the MNECB-based paths described in LEED-Canada, June 2003 edition. For EAc1, we will apply full cycle emission factors for Ontario and provide these factors, with references, as per the example in LEED-BC. Please confirm that this is acceptable.
