November 30, 2011 - The 2011 National Energy Code of Canada for Buildings (NECB) provides minimum requirements for the design and construction of energy-efficient buildings, covering: the building envelope; systems and equipment for HVAC; service water heating; lighting; and the provision of electrical power systems and motors.

It applies to new buildings, as well as to substantial renovations in existing ones. It does not apply, however, to farm buildings nor to housing and smaller buildings covered in Part 9 of the National Building Code of Canada (NBC).
The NECB is in an objective-based code format in which all requirements are linked to a new sub-objective, Excessive Use of Energy, under a new principal objective, Environment. The NECB is available in print and digitally.
