Single-Family Construction

2009 IRC, Chapter 11

Effective January 1, 2012, the Texas State Energy Conservation Office adopted the 2009 International Residential Code (Chapter 11) as the state-mandated energy code for all residential construction, one- and two-family residences of three stories or less above grade. The new code updates the Texas Building Energy Performance Standards previously based on the 2000 IECC with 2001 Supplement.

Compliance Software

REScheck™
REScheck was developed to simplify and clarify code compliance with the IECC and a number of state codes. The REScheck residential compliance materials offer two ways to demonstrate compliance: the trade-off approach and the prescriptive packages approach.

IC3
The Code Compliance Calculator (IC3) is a web-based software tool designed to provide a simulated performance of energy code compliance for single-family residential construction. The tool can capture quantitative above-code compliance as well as emissions reduction credits for the State Implementation Plan (SIP). This software tool has been developed by the Energy Systems Laboratory (ESL) at Texas A&M University.
