标准摘要
[中文适用范围]： ISO 15927 的本部分规定了用于评估建筑物空间供暖所用能源的累积温差数据的定义、计算方法和表示方法。这些通常以度小时或度日表示，这些数据通常简称为“供暖度小时”或“供暖度日”。ISO 15927 的本部分包括基于每小时或每日平均温度计算累积温差的近似方法，以及用于估算任何基准温度的月值的近似方法，用于在无法获得直接从气象气温记录计算出的数据时使用。在一些国家，使用不同于基准温度的阈值温度。ISO 15927 的本部分不涵盖这一点。 [外文原描述]： ISO 15927-6:2007 specifies the definition, method of computation and method of presentation of data on accumulated temperature differences, used for assessing the energy used for space heating in buildings. These are normally expressed in degree‑hours or degree-days, and such data are often referred to simply as "heating degree-hours" or "heating degree-days". ISO 15927-6:2007 includes approximate methods for calculating accumulated temperature differences based on hourly or daily mean temperatures and for estimating monthly values to any base temperature, for use when data computed directly from meteorological air temperature records are not available. In some countries, a threshold temperature different from the base temperature is used. ISO 15927-6:2007 does not cover this.
