List the types and efficiencies of heating, cooling and service water heating equipment. Where a gas-fired unvented room heater, electric furnace or baseboard electric heater is installed in the residence, the certificate shall list “gas-fired unvented room heater,” “electric furnace” or “baseboard electric heater,” as appropriate. An efficiency shall not be listed for gas-fired unvented room heaters, electric furnaces or electric baseboard heaters. 3. Indicate which areas have been designed and constructed as conditioned or unconditioned space. 4. Include the following text: “The addition of mechanical cooling or heating to an unconditioned space requires a permit. The addition of cooling without proper design and construction can have adverse health, safety, and conservation consequences.”” (34) Subsection R402.1 of the International Energy Conservation Code is amended to read as follows: “R402.1 General (Prescriptive). The building thermal envelope shall meet the requirements of Sections R402.1.1 through R402.1.5. Exception: The following low-energy buildings, or portions thereof, separated from the remainder of the building by building thermal envelope assemblies complying with this section shall be exempt from the building thermal envelope provisions of Section R402. 1. Those with a peak design rate of energy usage less than 3.4 Btu/h•ft² (10.7 W/m²) or 1.0 watt/ft² (10.7 W/m²) of floor area for space-conditioning purposes. 2. Unconditioned space that does not contain habitable space. 3. Unconditioned dwellings with enclosed habitable areas less than 1,100 square feet. 4. Dwellings with permitted, off-grid, self supplying photovoltaic with battery back up.” SUPP. 9 (1-2021) 5E-17
