UNE-EN 15316-1:2018

This standard is the general frame for the calculation of the energy performance of heating and domestic hot water systems. It specifies how to perform the calculation of the entire system using the calculation modules defined in the respective standards. It deals with common issues like operating conditions calculation and energy performance indicators.This standard specifies the structure for the calculation of energy requirements of space heating and domestic hot water systems in buildings. It standardises the required inputs and outputs in order to achieve a common European calculation method.It allows the energy analysis of the different heating and Domestic hot water sub-systems including control (emission, distribution, storage, generation) by comparing the system losses and by defining system performance factors. The performance analysis allows the comparison between sub-systems and make possible to monitor the impact of each sub-system on the energy performance of a building. The calculation of the system losses of each part of the heating sub-systems is defined in subsequent standards Ventilation systems are not included in this standard (e. g. balanced systems with heat recovery), but if the air is preheated or an air heating system is installed, the systems providing the heat to the AHU (Air Handling Unit) are covered by this standard.
