2001年，德克萨斯州通过了《国际节能规范》（IECC），以帮助减少住宅建筑的年供暖和制冷负荷。2006年后，德克萨斯州立法机构要求采用IECC 2006，并要求我们的实验室跟踪德克萨斯州建筑能源性能标准（TBEP）实施过程中的年度节能和氮氧化物减排。本文讨论了使用公用事业账单分析方法验证IECC 2000/2001和IECC 2006建筑规范inTexas的节能效果。在该方法中，仔细选择了分析过的房屋样本，并将其分为三组- 由同一建筑商建造的家庭住宅，建筑类型非常相似。每一组都是在不同的时期建立的，以考虑不同采用规范的影响。这项研究表明，与按照先前标准建造的房屋相比，应用2000/2001年IECC和2006年IECC节省的电力分别约为20%和19%。引文:ASHRAE论文CD:2014 ASHRAE年会，华盛顿州西雅图

The International Energy Conservation Code (IECC) was adopted in 2001 by the State of Texas to help reduce annual heating and cooling loadsin residential buildings. After 2006, the Texas Legislature required that the IECC 2006 be adopted and requested our Laboratory to track theannual energy savings and NOx emission reductions from the implementation of the Texas Building Energy Performance Standards (TBEPS).This paper discusses the verification of the energy savings from the implementation of the IECC 2000/2001 and IECC 2006 building codes inTexas using a utility bill analysis methodology. In the methodology, a sample of analyzed houses was carefully selected and separated into threegroups of single-family residential houses that were constructed by the same builder, with very similar construction types. Each group was built in adifferent period to account for the impact of the different adopted codes. This study shows that the electricity savings from the application of the2000/2001 IECC and the 2006 IECC are approximately 20% and 19%, respectively when compared to houses built to prior standards.
