National Energy Code of Canada for Buildings (NECB)

The 2011 National Energy Code of Canada for Buildings (NECB) provides minimum requirements for the design and construction of energy-efficient buildings and covers the building envelope, systems and equipment for heating, ventilating and air-conditioning, 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 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 the following formats. To order, visit the NRC Virtual Store.

The NECB was prepared by the Canadian Commission on Building and Fire Codes in partnership with the provinces and territories with technical support and funding provided by the National Research Council of Canada and Natural Resources Canada.
