A certain friend of mine from Canada pointed out to me late last week that the only exemption for requiring a fixed heater in the main living room-sized per the heating capacity calculator are Certified Passive House or certain Living Building Challenge buildings.
See the text from the act:
11 Exemption for certified passive buildings
(1) The main living room need not comply with regulation 8 if the tenancy building is a certified passive building.(2) A building is a certified passive building if—(a) one of the following applies:(i) the building has been certified as a passive house under the Passive House Standard of the Passivhaus Institut, Germany:(ii) the International Living Future Institute has issued one of the following in respect of the building:(A) a Living Building Certification:(B) a Petal Certification that includes a heating related requirement:(C) a Zero Energy Certification; and(b) that certification has not lapsed, expired, been cancelled, or otherwise ceased to be in force.
This may not sound so vital to those building a single-family home but for multifamily buildings, this could be huge.
