许多根据测量的天气相关能耗数据估算节能的方法试图通过识别改装前能耗和室外空气温度的经验模型来补偿改装前后不同的天气条件。即使改造前的模型可能包括平衡点或变化点温度，使用该方法确定的节约量也隐含地假设，在改造前，室内空气设定点温度和内部热增益是相同的- 以及改造后的时期。在本文中，我们开发了简化表达式，表明改装节省的估算对改装前后室内空气温度和内部热增益的微小变化高度敏感。这一观察结果在一项移动家庭气候化研究中得到了证实，该研究估计，在考虑和不考虑改变室内空气温度的情况下，节省的费用变化高达89%。这些发现表明，在简单建筑中，通过定期测量室内和室外空气温度，并明确将其纳入估算节约的基线模型，可以显著提高估算节约的准确性。 单位:双引证:研讨会，ASHRAE交易，1998年，第104卷，第2部分，多伦多

Many methods of estimating energy savings from measured weather-dependent energy consumption data attempt to compensate for varying weather conditions between the pre- and post-retrofit periods by identifying an empirical model of pre-retrofit energy consumption and outdoor air temperature. Even though the pre-retrofit model may include a balance-point or change-point temperature, savings determined using this method implicitly assume that the indoor air set-point temperature and internal heat gains are the same during the pre- and post-retrofit periods. In this paper, we develop simplified expressions that suggest that estimates of retrofit savings are highly sensitive to minor changes in indoor air temperature and internal heat gains between the pre- and post-retrofit periods. This observation is confirmed in a mobile-home weatherization study where savings estimated with and without considering changing indoor air temperature varied by as much as 89%. These findings suggest that in simple buildings, the accuracy of estimated savings can be significantly improved by routinely measuring both indoor and outside air temperatures and explicitly including them in the baseline model for estimating savings.Units: Dual
