Plain English Breakdown

The bill summary and official text indicate a specific effective date of July 1, 2025.

Roof Standards Act

This bill clarifies that certain energy-saving roof standards for low-sloped roofs set by the International Energy Conservation Code (IECC) do not apply to Tennessee's building codes as of July 1, 2025.

What This Bill Does

  • Clarifies that the solar reflectance and thermal emittance requirements for low-sloped roofs in the IECC do not apply to Tennessee starting from July 1, 2025.
  • Gives the state fire marshal authority to create rules to enforce this change.

Who It Names or Affects

  • Home and building owners in Tennessee who construct or renovate low-sloped roofs after July 1, 2025.
  • Construction companies working on buildings with low-sloped roofs in Tennessee after July 1, 2025.

Terms To Know

International Energy Conservation Code (IECC)
A set of rules that help save energy by making buildings more efficient.
Solar reflectance
How well a surface reflects sunlight, which can affect how hot or cool a building gets.

Limits and Unknowns

  • The bill does not specify if it affects all counties equally; some Tennessee counties fall under different climate zones.
  • It is unclear what the impact will be on energy savings and roof maintenance costs.

Amendments

These notes stay tied to the official amendment files and metadata from the legislature.

Amendment 1-0 to HB0801

Plain English: This amendment changes Tennessee's building code to exclude certain energy conservation requirements for low-sloped roofs from applying to the 2021 International Code Council adoption.

  • Exempts low-sloped roofs from having to meet solar reflectance and thermal emittance standards set by the International Energy Conservation Code in the 2021 version of the code.
  • Gives the state fire marshal authority to create rules that support this change, following specific administrative procedures.
  • The exact impact on energy efficiency and building costs is not detailed in the amendment text.
Amendment 1-0 to SB1194

Plain English: This amendment changes Tennessee's building code to exclude certain energy efficiency requirements for low-sloped roofs from applying to the 2021 International Code Council adoption.

  • Exempts low-sloped roofs from having to meet solar reflectance and thermal emittance standards set by the International Energy Conservation Code in the 2021 version of the code.
  • The amendment text does not specify which exact requirements are being excluded, so it's unclear what specific energy efficiency measures will no longer apply to low-sloped roofs.
  • It is also unknown how this change will affect overall energy conservation efforts in Tennessee.

Official Summary Text

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.
