Volume 21, Number 1
The Canadian Commission on Building and Fire Codes (CCBFC) invites all interested parties to take part in its fall 2017 public review of proposed changes to the 2015 editions of Codes Canada publications from November 6, 2017 to January 2, 2018.
This second public review of the 2015 code cycle focuses on changes being proposed to the 2015 editions of the National Building Code (NBC), the National Fire Code (NFC) and the National Plumbing Codes (NPC).
The proposed changes address issues related to:
- Fire protection in Part 3 of the NBC and in Part 5 of the NFC
- Earthquake design in Part 4 of the NBC
- Structural Design in Part 4 of the NBC
- Environmental separation in Part 5 of the NBC
- Farm buildings occupancy classification
- HVAC in Part 6 of the NBC and the plumbing in the NPC
- Housing and small buildings in Part 9 of the NBC
- Encapsulated mass timber construction
- Hazardous material and activities in the NFC
- Asbestos in the NBC and the NPC
With an interim change planned for publication in late 2017, no changes are being proposed for the National Energy Code for Buildings this public review.
Of particular interest to some Code users, the 2017 public review introduces a recommended approach to update the provisions related to farm buildings. A task group on Farm Buildings is reviewing risks and hazards related to farm buildings in a multi-phased approach. The work will update design requirements for large farm buildings and other structures like silos and grain bins, and move them into the NBC. The initial phase introduces a new major occupancy classification, Group G agricultural, with different divisions, as farm buildings can include a wide variety of uses that do not fall neatly into one occupancy classification.
The NBC currently has two construction types, combustible construction and noncombustible construction. Developers, architects, engineers and builders across Canada are seeking additional options for buildings permitted to be of combustible construction and there is an increased interest in the positive environmental attributes of wood. A third construction type is proposed for inclusion in the NBC and NFC called Encapsulated Mass Timber Construction (EMTC).
Explanations of the proposed changes, as well as instructions on how to submit comments, are provided on the website. Following the review, all comments will be considered and recommendations on the proposed changes will be made.
