建筑能耗性能评级方法提供了一种比较一栋建筑与其他类似建筑能耗的方法。建筑业主可以使用评级方法来确定节能改造投资是否合理。开发商正在使用建筑节能性能评级来展示高性能建筑。租户被吸引到具有高能效等级的建筑中，以此将设施运营成本降至最低。通过强调高效建筑，能源性能评级方法刺激了使用较少能源的建筑的设计和施工。 能源效率有助于建筑的整体可持续性，这也包括土地使用、水资源使用和材料使用。通过正式文献搜索和非正式互联网搜索，发现了许多不同的评级方法，包括47个商业建筑协议和31个适用于住宅的协议。为了测试和理解这些协议的评级，从实际建筑中收集数据。本文报告的研究重点是建筑节能性能评级方法。单位:I-P

Building energy performance rating methods provide a way to compare the energy consumption of one building with other similar buildings. Building owners may use rating methods to determine if investment in energy efficiency retrofits is justified.  Developers are using building energy performance ratings to showcase high performance buildings.  Tenants are attracted to buildings with high energy performance ratings as a way to minimize facility operating costs.  By highlighting efficient buildings, energy performance rating methods stimulate the design and construction of buildings using less energy.  Energy efficiency contributes to overall building sustainability, which also includes land use, water use, and material use.Many different rating methods were uncovered by a formal literature search and an informal Internet search including 47 protocols for commercial buildings and 31 that applied to residences. In order to test and understand the ratings from these protocols, data from actual buildings was gathered.The focus of the research reported in this document is building energy performance rating methods.Units: I-P
