对于实现节能住宅，围护结构性能审计变得越来越重要。提出了一种基于模型的围护结构性能评估方法，通过对室内外温度和暖通空调开/关状态的10天测量来评估房屋的热性能和气密性。通过使用1676个家庭（由智能恒温器制造商提供）的数据进行测试，发现所提出的方法确定的居龄和房屋围护结构性能恶化之间存在明显的相关性，这与预期相符。虽然需要更多的测试来了解主包络条件的地面真实性，但所提出的方法被证明是有前途的。 引用:2019年年度会议，密苏里州堪萨斯城，扩展摘要

Envelope performance audits are becoming increasingly important for achieving energy-efficient homes. A model-based envelope performance evaluation method is proposed to evaluate the thermal properties and air-tightness of a house using 10-day measurements of its indoor and outdoor temperatures and HVAC on/off status. Through a test using data from 1,676 homes (provided by a smart thermostat manufacturer), a distinctive correlation between home age and home envelope performance deterioration identified by the proposed method was found, which aligned well with expectations. Although more tests with knowledge of the ground truth of the home envelope condition are needed, the proposed method is shown to be promising.
