DIN EN 15378-3:2017-09

This document specifies methods to assess the delivered energy for space heating and domestic hot water energy performance of a building based on measurements during the operation and occupancy phase. It covers the assessment of the energy performance of the space heating and domestic hot water supply of a building or building elements based on measurements. This includes: - assessment of the performance of the building related to space heating and domestic hot water based on the amount of energy supplied; - assessment of the energy performance indicators of heating and domestic hot water systems, subsystems and building elements based on measurements. This standard does not cover the measurement of delivered energy for ventilation, cooling, air conditioning and lighting systems. This document has been prepared by Technical Committee CEN/TC 228 "Heating systems in buildings", the secretariat of which is held by DIN. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association and supports essential requirements of EU Directive 2010/31/EU.
