Radiant heating systems can now be installed in Alberta without adhering to former insulation requirements set forth in section 9.36 of the National Model Energy Code for Buildings.
The provincial building administrator and provincial plumbing/gas administrator have developed a Standata variance, signalling the end of “intense insulation requirements” on Alberta’s hydronics industry.
“There is sufficient evidence that indicates that the current under-slab insulation code provisions are excessive and jeopardize the availability of hydronic heating as an option for Albertans,” the variance states.
Alberta Municipal Affairs will consult with the National Research Council to recommend “an appropriate insulation rating that will allow for hydronic heating installations while also supporting Alberta’s energy efficiency goals.”
In the interim period, the province-wide variance will allow for less than four inches of under-slab insulation where hydronic or radiant heating is installed.
CHC, the Canadian Institute of Heating and Plumbing (CIPH) and the Mechanical Contractors Association (MCA) of Alberta have long urged the province to take action on they called a “crisis.”
