Bibliography

Describes the methods for calculation of system energy requirements and system efficiencies of heating systems in buildings.

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. This European Standard specifies the: - inputs; - calculation methods; outputs.
