|The Model National Energy Code of Canada for Buildings
1997 (MNECB) is intended to help you design energy-efficient buildings that
minimize air-conditioning and heating bills given construction cost trade-offs.
The Code contains cost-effective minimum requirements for energy efficiency in
new buildings. The MNECB applies to all buildings, other than houses of three
storeys or less, and to additions of more than 10 m2 to such buildings. One of
a pair of energy codes, the MNECB applies to heated or cooled buildings other
than those covered by the Model National
Energy Code for Houses (MNECH).
The MNECB, by considering
climate, fuel types and costs, and regional construction costs, establishes
minimum standards that can be adopted as regulations by the appropriate
provincial or territorial authorities or simply used as sound energy
conservation practice in construction by both industry and corporations. The
Code applies to new construction or additions, but not to alterations or
renovations of existing buildings (unless they are so extensive that they
amount to new construction).
