HB 801

Present law provides several statewide building construction safety standards. This bill specifically prohibits the roof solar reflectance and thermal emittance requirements for low-sloped roofs, set by the International Energy Conservation Code (IECC) and published by the International Code Council, from applying to this state. The IECC standard requires low-sloped roofs directly above cooled conditioned spaces in climate zones 0 through 3 to comply with one or more of certain solar reflectance and thermal emittanc e options to generally save energy and prevent concentrated heat. Several counties in this state fall under zone 3, while all other counties are in zone 4. The zone 3 counties are Bedford, Chester, Coffee, Crockett, Davidson, Decatur, Dyer, Fayette, Fran k lin, Gibson, Giles, Grundy, Hamilton, Hardeman, Hardin, Haywood, Henderson, Hickman, Lauderdale, Lawrence, Lewis, Lincoln, Madison, Marion, Marshall, Maury, McNairy, Moore, Perry, Rutherford, Shelby, Tipton, Wayne, and Williamson counties. ON MARCH 24, 2 025, THE HOUSE ADOPTED AMENDMENT #1 AND PASSED HOUSE BILL 801, AS AMENDED. AMENDMENT #1 rewrites the bill to, instead, clarify that, as of July 1, 2025, t he roof solar reflectance and thermal emittance requirements of the International Energy Conservatio n Code for low-sloped roofs do not apply to the 2021 International Code Council adoption. The state fire marshal is authorized to promulgate rules to effectuate this amendment.
