DIN EN 15316-1:2017-09

This European Standard is the general frame for the calculation of the energy use and the energy performance of heating and domestic hot water systems. This standards is only dealing with the heat, provided by water based systems, needed for heating, domestic hot water and cooling (for example, absorption chiller). It specifies how to perform the calculation of the entire installation using the calculation modules (see Table 2) corresponding to the methods defined in the respective standards. It deals with common issues like operating conditions calculation and energy performance indicators. It standardises the inputs and outputs in order to achieve a common European calculation method. It allows the energy analysis of the heating and Domestic hot water systems and sub-systems including control (emission, distribution, storage, generation) by comparing the system losses and by defining energy performance indicators. The performance analysis allows the comparison between systems and sub-systems and makes possible to evaluate 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 (for example, 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. This document (EN 15316-1:2017) has been prepared by Technical Committee CEN/TC 228 "Heating systems in buildings" (secretariat: DIN, Germany). Working Committee NA 041-05-01 AA "Energetic assessment of building services installations (SpA ISO/TC 205 "Environmentally friendly building design")" at DIN Standards Committee Heating and Ventilation Technology and their Safety (NHRS) is responsible for the German version. In Germany, the Directive on the energy performance of buildings (2010/31/EU) of the European Parliament and the European Council is primarily implemented by national energy conservation law. National energy conservation law refers to dated national and European standards and national prestandards that have been specified to be implemented in Germany.
