本欧洲标准涵盖了计算单室，建筑物和建筑物的设计热负荷的方法，其中设计热负荷定义为在设计外部条件下维持所需内部设计温度所需的供热（功率）。 表1显示了在prEN ISO 52000 1中规定的模块化结构的上下文中，该标准在EPB标准集中的相对位置。 注1:在FprCEN ISO/TR 52000 2中，可以找到相同的表格，每个模块都有相关EPB标准的编号和随附的技术报告已经发布或正在准备中。 注2:模块代表EPB标准，尽管一个EPB标准可以覆盖多个模块，一个模块可能被一个以上的EPB标准覆盖，例如简化和详细的方法。另见第2条和表A.1和B.1

This European Standard covers methods for the calculation of the design heat load for single rooms, building entities and buildings, where the design heat load is defined as the heat supply (power) needed to maintain the required internal design temperature under design external conditions. Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000 -1. NOTE 1 In CEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation. NOTE 2 The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively.
