BS EN 15316-3-3:2007

This standard BS EN 15316-3-3:2007 Heating systems in buildings. Method for calculation of system energy requirements and system efficiencies is classified in these ICS categories:

• 91.140.10 Central heating systems

This European Standard is part of a set of standards covering the methods for calculation of system energy requirements and system efficiencies of heating systems in buildings. In particular this 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 generation system; - recoverable thermal losses for space heating from the domestic hot water generation system; - auxiliary energy of the domestic hot water generation systems. 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.
