Regulatory Update – Alberta

As reported on previously, regulations governing insulation requirements beneath a heated slab in hydronic heating installations were significantly affecting the marketplace (Section 9.36. of the Alberta Building Code 2014 (ABC 2014). In brief the insulation requirements in this regulation seemed only to boost construction costs, while offering little in the way of performance benefits.


Over the past couple of years, the Canadian Hydronics Council (CHC) has engaged the Province of Alberta on this matter. Presenting modeled data demonstrating the performance of homes meeting the regulation and comparing it with the requirements contained within CSA B214:  The Installation Code for Hydronic Heating Systems, demonstrated that the new regulation was more rigorous then needed to create an efficiently heated home.


Throughout this process the Province has been very open to receiving submissions from the CHC and over the summer they announced that they would draft a STANDATA addressing presented concerns.

This was published on October 3 acknowledging that “current under slab-insulation code provisions are excessive and jeopardize the availability of hydronic heating as an option for Albertans”


As a resolution, the STANDATA references a “province-wide variance will allow an alternative solution to the provisions under 9.36. and is strongly recommended for use in installations”.  It also contains reference to insulations requirement in CSA: B214.
