Inquiry
Canada does not have radon risk maps such as those developed by EPA and used to determine whether a project is or is not in EPA zone 1 and therefore whether or not it must install a radon mitigation system or has the option of doing so to earn a point under the rating system. Since there is no map & no way to assess risk, is the project eligible for a point if a radon mitigation system is installed?
Ruling
The prerequisite in Canada is to have the home tested for radon OR install radon resistant new construction. In order to earn 1 point, an active sub-slab or sub-membrane depressurization system must be installed. Applicable Internationally; Canada.
