ČSN EN 15378-3 This European Standard 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. This includes: - assessment of the amount of delivered energy carriers for space heating and domestic hot water preparation based on measurement; - assessment of the energy performance indicators of heating and domestic hot water systems and subsystems based on measurements. This standard does not cover the measurement of delivered energy for ventilation, cooling, air conditioning and lighting systems. This standard includes procedures to correct measured delivered energy according to climate and building use. Weighting (e.g. conversion into primary energy, cost, CO2 emission) of the measured delivered energy and assessment of the energy performance are covered in EN ISO 52000 1:2017. Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000 1:2017. NOTE 1 - In CEN ISO/TR 52000 2:2017 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation. NOTE 2 - The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively.
