该用于测量建筑物（1）的热质量的装置由位于建筑物内的热传感器（M1，M2，...）和位于建筑物内的外部传感器（20,30 ...）形成， 测试数据（200）的外部操作成员使用所述传感器的测量值以及建筑物的特征文件（205）作为输入。 为了评估通过建筑物外壳的热损失，建议使用以下指标： - 标准NF EN ISO 13790：2013中定义的Htr传热传热系数（W / K） 。 - 由于空气渗透而导致空气更新的换热系数，标准NF EN ISO 13790：2013中定义的Hve（W / K）。 - 由于空气渗透和热传导，通过被测建筑物外壳的整体热损失系数Htot（W / K）由下式定义：Htot = Htr + Hve应用： 通过建筑物的信封。

This measuring device of thermal properties of a building (1) is formed of thermal sensors (M1, M2, ..) located inside the building and external sensors (20, 30, ..) located, the outside, operating the test data elements (200) input by using the measurements of said sensors and also a feature of buildings file (205). It is proposed for the evaluation of heat loss through the building envelope to be based in particular on the following indicators:
- heat transfer coefficient by transmission Htr (W / K) defined in the standard NF EN ISO 13790: 2013.
- heat transfer coefficient by ventilation, due to air infiltration, Hve (W / K) defined in the standard EN ISO 13790: 2013.
- overall heat leakage through the shell of the test vessel, due to air infiltration and thermal transmissions, Htot (W / K) defined by the following formula: $$H_{\mathit{early}}=H_{\mathit{tr}}+H_{\mathit{ve}}$$ Application: Measurement of heat loss through the building envelope.
