National Energy Code of Canada for Buildings

A Public Review of NPC and NECB is underway.

The Canadian Commission on Building and Fire Codes (CCBFC) invites Code users and stakeholders to participate in the fall 2016 public review of proposed changes to Codes Canada publications: National Plumbing Code of Canada 2015 (NPC), and National Energy Code of Canada for Buildings 2015 (NECB). This national public review started October 11 and ends at 4:00 p.m. EST on December 9, 2016.
The purpose of the public review is to provide Code users and stakeholders with a detailed look at proposed technical changes and seek comment on each proposed technical change as to whether it should be approved, altered, or rejected.
The relevant committees of CCBFC will review every comment that was received up to that date. The committees will then either withdraw the proposed change; recommend that it be reviewed further for possible re-submission in revised form in a future public review; or recommend that it be approved by CCBFC, with or without modification. If approved by the CCBFC, the technical changes will be published in the 2020 editions of Codes Canada publications.

Summary of significant proposed changes – Fall 2016

Reference standards for backflow preventers more consistently

Clarify requirements for air pressure testing of drainage or venting systems
