Texas State Energy Conservation Office adopts the 2009 IRC chapter 11
In June 2010, SECO officially adopted updates to both the commercial and residential energy codes in Texas. The new code for single-family homes is based on 2009 IRC, Chapter 11 (effective January 1, 2012) and the new code for other residential, commercial, and industrial buildings is based on 2009 IECC (effective March 1, 2011). Local ordinances can continue to adopt local amendments provided that the Energy Systems Laboratory (ESL) of Texas A&M University first reviews and accepts them.
The following is extracted from the SECO website
The Comptroller of Public Accounts adopts new §19.53, concerning building energy efficiency performance standards, with changes to the proposed text as published in the March 26, 2010, issue of the Texas Register (35 TexReg 2514). The new section is created in compliance with Health and Safety Code, §388.003(b-1), which authorizes the State Energy Conservation Office (SECO) to adopt equivalent or more stringent energy codes than those adopted in Health and Safety Code, §388.003(a) and (b).
The agency responds that the agency will send a letter to all local governmental entities making them aware of the building energy code update. The letter will include the following: the agency will acknowledge that the adopted building energy codes set a minimum standard statewide.
§19.53.Building Energy Efficiency Performance Standards.
(a) Single-family residential construction. Effective January 1, 2012, the energy efficiency provisions of the International Residential Code as they existed on May 1, 2009, are adopted as the energy code in this state for single-family residential construction as it is defined in Health and Safety Code, §388.002(12).
(b) All other residential, commercial, and industrial construction. Effective April 1, 2011, the International Energy Conservation Code as it existed on May 1, 2009, is adopted as the energy code for use in this state for all residential, commercial, and industrial construction that is not single-family residential construction under subsection (a) of this section.
This agency hereby certifies that the adoption has been reviewed by legal counsel and found to be a valid exercise of the agency's legal authority.
Filed with the Office of the Secretary of State on May 24, 2010.
