National Energy Code for Buildings
The document outlines the National Energy Code for Buildings (NECB) 2011 and 2015, detailing efficiency improvements, compliance options, and specific requirements for various building components such as HVAC, lighting, and building envelopes. It highlights the importance of energy intensity metrics and local compliance considerations based on climate zones. Additionally, it mentions initiatives like the RealPAC 20 by '15 and Architecture 2030, focusing on achieving substantial energy efficiency targets over the coming years.
