The current National Energy Code of Canada for Buildings (NECB 2015) The NECB outlines the minimum energy efficiency levels for all new buildings and offers more flexibility for achieving code compliance. In 2011, the MNECB was updated and renamed the National Energy Code for Buildings (NECB) for consistency with the other model national construction codes (NBC, NPC, NFC) including an average 25 percent performance improvement over its predecessor. It was Canada’s first national standard for building energy performance and it influenced the way buildings were designed in Canada for more than 15 years. How Canada got its energy codeĪ consortium of provinces, utilities, industry stakeholders, the National Research Council of Canada (NRC) and Natural Resources Canada developed the Model National Energy Code for Buildings (MNECB) in 1997.
