Masonry Firewalls

Even though this information is a few years old, and based on an older version of the Nation Building Code of Canada; it still holds a wealth of great information related to firewall construction and detailing.

2015 National Energy Code for Buildings

We recommend that you check to see what your designer will be using for minimum energy efficiency design requirements…

The National Energy Code of Canada for Buildings 2015 (NECB), published by NRC and developed by the Canadian Commission on Building and Fire Codes in collaboration with Natural Resources Canada (NRCan), sets out technical requirements for the energy efficient design and construction of new buildings. The NECB 2015 includes over ninety changes improving the overall energy performance of buildings over the 2011 edition.

The 2015 edition broadens the scope to address all service water and introduces requirements for pressure-sensing controls which reduce the short-cycling of booster pumps when demand for water is low. Other HVAC and service water changes include equipment efficiency regulation of heat rejection equipment, such as cooling towers and (standalone) condensers, heating performance requirements for gas-fired outdoor packaged units and updated minimum pipe and duct insulation requirements. Lighting power density values and controls have been updated with more stringent lighting allowances and additional requirements for common spaces and exterior applications. The performance path modeling rules and guidance have been updated to reflect the changes to the prescriptive path as well as more current typical use profiles of buildings. Application of the code for residential and small buildings has also been clarified.

The NECB 2015 has been re-organized to consolidate relevant information. Each Part now contains the Prescriptive Requirements, followed by the Attribution Table and related (appendix) Notes.

The NECB is a must-have for building designers, energy consultants and subcontractors, construction professionals and regulatory officials.

Insulation and Vapour Barrier

This may be significantly more work than that which is required by minimum requirements under the 2010 NBCC, but this house gets an a+ for insulation and vapour barrier work! The insulation fills the full depth of the stud cavity and there are no overlaps or over compressed locations, and the vapour-barrier is properly lapped and sealed (to every single stud and truss and wall plate) with acoustical caulking. And there are vapour boxes at every single switch and fixture location, and there is vapour barrier over every single interior wall double top plate to ensure continuity of the system. In case you are wondering, the 2010 NBCC does not require you to use this much acoustical caulking.
