This European Standard covers energy performance calculation of water based distribution systems for space heating, space cooling and domestic hot water.
This standard deals with the heat flux from the distributed water to the space and the auxiliary energy of the related pumps.
The heat flux and the auxiliary energy for pumps can be calculated at any time-step (hour, month and year). The input and output data are mean values of the time step.
