Updated: 30/03/2020 Page 2of 4. To address this issue, some provincial and territorial building codes set different thermal resistance requirements for different climate zones, which are usually determined by the number of heating degree days (HDD). In December 2012, the Federal Government issued an amendment to the 2010 NBC to incorporate energy efficiency standards in housing (Section 9.36), and issued standards for energy efficiency in commercial, industrial, institutional, and large residential buildings [currently the 2015 National Energy Code of Canada for Buildings (NECB)]. This code directly references ASHRAE 90.1.-2016 for technical requirements and also requires completion of the 2019 Oregon Zero Energy Ready Commercial Code Compliance Form which may be completed using the ZERO Code Energy Calculator. The climate zones are under the jurisdiction of the provincial governments, which may vary from those in the national model codes.Â When Section 9.36 or the 2015 NECB are adopted, the provincial or municipal governments may adopt or adapt the climate zones. Insulation level are specified by R-Value. Table 1 lists the requirements from the Alberta code. The use of nominal values is easier for the insulation industry, since the product packaging is marked with these values and they directly correlate with the amount of insulation required in a building assembly (e.g., above ground walls, roofs). The general trend in energy codes includes a move towards more insulation and less air infiltration through the building envelope. Note that the 2015 National Energy Code for Buildings (NECB) expresses insulation requirements not as minimum thermal resistance (R effective), but as maximum thermal transmittance, designated by the letter U. U is simply the reciprocal of R (effective). R-Value is a measure of insulation’s ability to resist heat traveling through it. The approximate cost of framing and insulating materials to insulate an unfinished All of the above applies to the way housing codes are written in Canada.

Improving energy efficiency standards for building construction codes supports greenhouse gas emissions reduction and reduces the demand on Alberta's energy resources. R: Imperial unit of measurement for thermal resistance, RSI: Metric unit of measurement for thermal resistance. In Canada, building codes are under the jurisdiction of the provinces and territories, with some chartered municipalities that have the power to mandate their own standards for their building by-laws. Some jurisdictions express minimum thermal resistance codes using nominal values, others using effective values. The total number of HDD over the heating season indicates the relative severity of the winter for a specific location. • The mandatory minimum insulation in 2x6 framed walls is R-20. Timely code adoption will apply to the 2020 code publication cycle for the building, fire, plumbing and energy codes. 1981 (Alberta Building Code) were required to have a minimum insulation level of RSI 1.4 (R8) for above grade portions of basement walls.
