本报告总结了为德克萨斯州四大气候区住宅应用地热热泵改造开发节能估算的工作。德克萨斯州公用事业委员会第25.181条实质性规则要求该州的电力公司在2004年1月1日之前，通过旨在减少客户购买的能源消耗和/或需求的能效计划，实现需求增长至少减少10%。制定此类计划需要对各种节能措施的视为节约进行估算。在评估路易斯安那州一个大型美国陆军设施的住宅地热热泵改造项目期间所做工作的基础上，作者对200多户住宅的完整社区的性能进行了建模，比较了阿马里洛的地热或地面耦合热泵（GCHPs）和10个SEER空气源热泵的年能耗和峰值需求，达拉斯/沃斯堡、休斯顿和科珀斯克里斯蒂。 对三种不同的GCHP效率水平进行了建模，并对有无减温器的系统进行了建模，以补充家用热水箱。研究发现，在所有四个城市中，中效和高效GCHP都能显著节约能源和需求。单位:I-PCITION:研讨会论文，大西洋城，2002年

This report summarizes work to develop savings estimates for geothermal heat pump retrofits in residential applications in the four major climatic regions of Texas. Substantive Rule §25.181 of the Public Utility Commission of Texas requires electrical utilities in that state to achieve, by January 1, 2004, a minimum 10% reduction in demand growth through energy efficiency programs designed to reduce customers' purchased energy consumption and/or demand. The development of such programs requires estimates of deemed savings 1 for various energy conservation measures. Building on work performed during the evaluation of a residential geothermal heat pump retrofit project at a large U.S. Army facility in Louisiana, the authors modeled the performance of a complete neighborhood of 200 multifamily residences, comparing the annual energy consumption and peak demand of geothermal or ground-coupled heat pumps (GCHPs) and 10 SEER air-source heat pumps in Amarillo, Dallas/Fort Worth, Houston, and Corpus Christi. Three different GCHP efficiency levels were modeled, and the systems were modeled both with and without desuper-heaters to supplement domestic hot water tanks. The medium-and high-efficiency GCHPs were found to provide significant energy and demand savings in all four cities.Units: I-P
