|
|
BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS: |
|
|
SECTION 1. Sections 388.003(i), (j), and (k), Health and |
|
|
Safety Code, are amended to read as follows: |
|
|
(i) A building certified by a national, state, or local |
|
|
accredited energy efficiency program and determined by the |
|
|
laboratory to be in compliance with the energy efficiency |
|
|
requirements of this section may, at the option of the |
|
|
municipality, be considered in compliance. The United States |
|
|
Environmental Protection Agency's Energy Star Program |
|
|
certification of energy code equivalency shall be considered in |
|
|
compliance. A home energy rating system index utilizing Standard |
|
|
301 of the American National Standard for the Calculation and |
|
|
Labeling of the Energy Performance of Dwelling and Sleeping Units |
|
|
using an Energy Rating Index, commonly cited as ANSI/RESNET/ICC |
|
|
301, as it existed on January 1, 2021, [The Energy Rating Index |
|
|
Compliance Alternative or subsequent alternative compliance path] |
|
|
as described by Subsection (j) shall be considered in compliance |
|
|
provided that: |
|
|
(1) the building meets the mandatory requirements of |
|
|
Section R406.2 of the 2018 International Energy Conservation Code; |
|
|
and |
|
|
(2) the building thermal envelope is equal to or |
|
|
greater than the levels of efficiency and solar heat gain |
|
|
coefficient in Table R402.1.2 or Table R402.1.4 of the 2018 |
|
|
International Energy Conservation Code. |
|
|
(j) For the purposes of this chapter, Standard 301 of the |
|
|
American National Standard for the Calculation and Labeling of the |
|
|
Energy Performance of Dwelling and Sleeping Units using an Energy |
|
|
Rating Index, commonly cited as ANSI/RESNET/ICC 301, as it existed |
|
|
on January 1, 2021, [the Energy Rating Index Compliance Alternative |
|
|
or subsequent alternative compliance path] used to measure |
|
|
compliance for single-family residential construction [in an |
|
|
optional compliance path of the energy efficiency chapter of the |
|
|
International Residential Code] that uses an energy rating index is |
|
|
as follows: |
|
|
(1) for climate zone 2, an energy rating index of: |
|
|
(A) [65 or lower from September 1, 2016, to |
|
|
August 31, 2019; |
|
|
[(B)] 63 or lower from September 1, 2019, to |

|
|
(D) 55 or lower on or after September 1, 2028; |
|
|
(2) for climate zone 3, an energy rating index of: |
|
|
(A) [65 or lower from September 1, 2016, to |
|
|
August 31, 2019; |
|
|
[(B)] 63 or lower from September 1, 2019, to |

|
|
(D) 55 or lower on or after September 1, 2028; and |
|
|
(3) for climate zone 4, an energy rating index of: |
|
|
(A) [69 or lower from September 1, 2016, to |
|
|
August 31, 2019; |
|
|
[(B)] 67 or lower from September 1, 2019, to |
