MetadataShow full item record
DescriptionIn 2007, the 80th legislature mandated the Energy Systems Laboratory (Laboratory) to take part in Texas rule-making process. As detailed in the Health and Safety Code, Chapter 388., Texas Building Energy Performance Standards, Sec. 388.003 (b-1), the Laboratory is required to submit written recommendations to the State Energy Conservation Office (SECO) on whether the energy efficiency provisions of the latest published editions of the International Residential Code (IRC) or the International Energy Conservation Code (IECC) for residential or commercial energy efficiency and air quality are equivalent to or more stringent than the provisions of editions previously adopted as the Texas Building Energy Performance Standards (TBEPS). This report, focusing on single-family residence provisions, is in support of the letter of recommendation sent to the State Energy Conservation office (SECO) on December 8, 2011. The report provides a detailed technical analysis comparing the stringency of the Texas Building Energy Performance Standards (TBEPS), based on Chapter 11 of the 2009 International Residential Code (2009 IRC) for single-family residential construction, to the recently published 2012 International Residential Code (2012 IRC), Chapter 11.
