在英国，无论何时出租或出售现有住宅，都会使用标准评估程序 (SAP) 来评估其能源性能。本研究调查了 SAP 的哪些输入对英格兰现有燃气中央供暖房屋的能源评级差异最大。 2009 年英国住房调查 (EHS) 的数据用于生成一组有代表性的住宅，然后应用基于方差的全局敏感性分析来评估每个输入对计算评级中方差的贡献。研究表明，供暖系统效率、外墙 U 值和住宅几何形状是英格兰燃气中央供暖房屋能效等级差异的 75% 的原因。这表明，提高供暖系统效率和性能最差住宅的墙U值将大大有助于提高其能源等级并有可能减少其能源消耗。研究还表明，住宅几何形状对计算的碳排放量（占方差的 80%）的影响远大于对 SAP 能源评级（占 30%）的影响，这意味着能源评级的显着改善可能不会伴随着碳排放的显着减少。
In the UK, the Standard Assessment Procedure (SAP) is used to rate the energy performance of existing dwellings whenever they are let or sold. This study investigates which of the inputs to SAP account for the most variance in energy rating across existing gas central heated houses in England. Data from the English Housing Survey (EHS) 2009 are used to generate a representative set of dwellings and variance-based global sensitivity analysis is then applied to assess each input's contribution to the variance in the calculated ratings. It is demonstrated that heating system efficiency, external wallU-value and dwelling geometry account for 75% of the variance of the energy rating of gas central heated houses in England. This suggests that improving heating system efficiencies and wallU-values of the worst performing dwellings will go a long way towards improving their energy rating and potentially reducing their energy consumption. It is also demonstrated that dwelling geometry has a much bigger influence on the calculated carbon emissions (accounting for 80% of the variance) than it does on the SAP energy rating (accounting for 30%), meaning that significant improvements in energy rating might not be accompanied by significant reductions in carbon emissions.
