Energy efficiency

Question 1:

How do the Codes address climate change?

Answer to question 1:

The national code documents do not directly address issues related to climate change mitigation. However, the climatic data that forms the basis for much of the design of buildings is continuously being updated in the National Building Code of Canada to ensure it is current. It is anticipated that adoption of the energy efficiency requirements in the National Energy Code of Canada for Buildings and in Part 9 (housing and small buildings) of the National Building Code of Canada will contribute to a reduction in greenhouse gas emissions.

Question 2:

How do the Codes address energy efficiency?

Answer to question 2:

The National Energy Code for Buildings directly addresses the use of energy as it relates to resource conservation under a new objective called “Environment”. The same Environment objective was incorporated in the NBC and provisions dealing with energy efficiency for housing and small buildings are found in Section 9.36. of the NBC.

Question 3:

How do the Codes address resource conservation?

Answer to question 3:

The new Environment objective in Codes Canada publications has a “Resources” sub-objective that, so far, addresses excessive use of energy and excessive use of water. It may be expanded in the future. This would only happen if extensive consultation with the provinces and territories and other stakeholders provides a broad consensus that such an expansion should occur.

Question 4:

Where can I find additional reading on the long-term strategy for energy code development?

Answer to question 4:

CCBFC Position Paper on a Long-Term Strategy for Developing and Implementing More Ambitious Energy Codes, September 14, 2016 Chapter on ‘Built Environment’ in the ‘Complementary actions to reduce emissions’ of the Government of Canada’s Pan-Canadian Framework on Clean Growth and Climate Change, December 14, 2016
