This European Standard is part of a series of standards on the method for calculation of system energy requirements and system efficiencies. The scope of this specific part is to standardize the: - required inputs; - calculation method; - resulting outputs, for space heating generation by: - air heating systems, including control; - overhead radiant heating systems for non-domestic use, including control; and - stoves and local heaters for residential use. This standard does not apply to heating systems that utilize water as a heat transfer medium. Other heat generation systems such as boilers, heat pumps and others are covered in other sub modules of M3-8. 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 prEN ISO 52000-1. NOTE 1 – In prCEN 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.
