First public review of Codes Canada 2015

Volume 20, Number 2

The Canadian Commission on Building and Fire Codes (CCBFC) invites all interested parties to take part in its first public review of proposed changes to the 2015 editions of Codes Canada publications from October 11 to December 9, 2016.

This first public review of the 2015 Codes will focus primarily on proposed changes to the 2015 editions of the National Energy Code for Buildings (NECB) and the National Plumbing Code (NPC).

A large package of changes is proposed to improve the energy performance of buildings. The proposed changes to the NECB aim to:

  • Reduce overall thermal transmittance of roofs, fenestration and doors;
  • Reduce losses through thermal bridging in building assemblies;
  • Reduce the allowable percentage of skylight area;
  • Introduce more stringent interior and exterior lighting requirements;
  • Require energy recovery systems;
  • Require temperature controls in individual guest rooms in hotels and motels;
  • Require demand control ventilation systems in commercial kitchens;
  • Clarify the lighting trade-off path requirements in Part 4; and
  • Make performance compliance requirements in Part 8 consistent with prescriptive requirements.

The proposed changes to the NPC aim to:

  • Reference standards for backflow preventers more consistently; and
  • Clarify requirements for air pressure testing of drainage or venting systems.

An explanation of the proposed changes, as well as instructions on how to submit comments, is provided on the website. Following the review, all comments will be considered and recommendations on the proposed changes will be made.
