This European Standard is part of a set of standards covering methods for calculation of system energy requirements and system efficiencies of heating systems in buildings. In particular this European Standard is one of a number of standards dealing with domestic hot water systems.
The scope of this specific part is to standardise the methods for calculation of:
- thermal losses from the domestic hot water distribution system;
- recoverable thermal losses for space heating from the domestic hot water distribution system;
- auxiliary energy of the domestic hot water distribution system.
These values are input data for calculation of the overall energy use according to prEN 15603 and EN 15316-1.
