Retrofitting a 1960s Split-Level Cold-Climate Home

The U.S. Department of Energy Building America research team Consortium for Advanced Residential Buildings (CARB) partnered with Preferred Builders, a previous CARB partner and builder of the Performance House (DOE 2013) and the owners of a 1960s split-level home in Westport, Connecticut, to evaluate and implement a cost-effective solution package that met the requirements of 30% source energy savings compared to the pre-retrofit performance. This home had already been updated aesthetically (kitchen and bathrooms), so the owners wanted the energy-efficiency measures to be as non-disruptive to the interior finishes as possible.

美国能源部建筑美国研究项目的先进住宅建筑联盟（Consortium for Advanced Residential Buildings，CARB），与首选建筑商（Preferred Builders）及康涅狄格州韦斯特波特一栋1960年代错层住宅的业主达成合作。其中，首选建筑商此前即为CARB合作伙伴，同时也是DOE 2013年性能住宅的建造方。三方合作评估并实施了一套经济高效的解决方案包，该方案可实现相较改造前性能30%的源端能源节省。该住宅此前已完成美学翻新（厨房与浴室），因此业主希望节能措施尽可能不对室内饰面造成干扰。
