EVS-EN 15316-3-2:2007

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.
