DIN EN 15316-4-1:2017-09

This European Standard is part of a series of standards on the method for calculation of system energy requirements and system efficiencies of space heating systems and domestic hot water systems. This standard (EN 15316-4-1) specifies: - required inputs; - a calculation method; - resulting outputs; - a method to take into account the energy performance of heat generation devices based on fuel combustion; for space heating generation by combustion sub-systems (boilers, biomass), including control. This standard specifies methods for the calculation of: - thermal losses from the heating and the domestic hot water generation system; - recoverable thermal losses for space heating from the heating and the domestic hot water generation system; - auxiliary energy of the heating and the domestic hot water generation systems. This standard specifies the energy performance calculation of water based heat generation sub-systems including control based on combustion of fuels ("boilers"), operating with conventional fossil fuels as well as renewable fuels. This standard does not cover sizing or inspection of boilers. This standard is also applicable to heat generators for heating or for combined service as domestic hot water, ventilation, cooling and heating. Generators for domestic hot water only are taken into account into part M8-8. This European Standard is the general standard on generation by combustion sub-systems (boilers, biomass) and is also intended for generation for domestic hot water production and/or space heating. These values are input data for calculation of the overall energy use according to EN ISO 52000-1 and EN 15316-1. This document (EN 15316-4-1:2017) 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) of the German Institute for Standardization e. V. 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. On the basis of the dated references, only the editions of these technical rules addressed in this manner are used. If the dated technical rules to be used under energy conservation legislation refer to undated technical rules, the latter shall be used in the version that corresponds to the status at the time of publication of the dated technical rule.
