This standard specifies methods to assess the energy performance to provide heating and domestic hot water to a building based on measurements. This standard covers the assessment of the heating and domestic hot water energy performance of a building or of building elements based on measurements. This includes: ¾ð assessment of the heating and domestic hot water performance of the building based on measurement of the amount of delivered energy carriers; ¾ð assessment of the energy performance of systems, subsystems and building elements, based on measurements. This standard does not cover measured energy performance on ventilation, cooling, air conditioning and lighting systems. Figure 1 shows the relative position of this standard within the EPB standards.
