2、ssibilities using smart meters使用智能测量仪的可能性estimation of ua and ga valuesua和ga值的估算estimation of energy signature/labelling能量标签的估算estimation of dynamic energy signature动态能量标签的估算estimation of time constants时间恒定的估算full dynamic model of the building建筑的全动态模型green it visit in china energy labelling of build

3、ings建筑的能源标签today building experts make judgements of the energyperformance of buildings based on drawings and prior knowledge. 今天，建筑专家根据图和先进知识来判断建筑能源的表现this leads to energy labelling of the building这导致了建筑能源的标签however, it is noticed that two independent experts can predict very different consumptions

4、 for the same house.然而，值得关注的是两个独立的专家对相同房屋做出不同的消耗估计green it visit in chinasimple estimation of ua-valuesua值的简单估计consider the following model (t=day no.) estimated by kernel-smoothing: 考虑以下模型（t=天） the estimated ua-value is:估计的ua值是：green it visit in chinaestimated ua-values估计的ua值green it visit in china
