BS EN 15316-5:2025

This standard BS EN 15316-5:2025 Energy performance of buildings. Method for calculation of system energy requirements and system efficiencies is classified in these ICS categories:

• 91.140.65 Water heating equipment
• 91.140.10 Central heating systems

This document specifies energy performance calculation of water based storage sub-systems used for heating, for domestic hot water or for combination of these. This document does not apply to sizing or inspection of such storage systems. Table 1 shows the relative position of this document 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. See also Clause 2 and Tables A.1 and B.1. Table 1 - Position of this document within the modular structure of the set of EPB standards [...table not reproduced...]
