ADOPTED_FROM:EN ISO 52000-1:2017 ISO 52000-1:2017 establishes a systematic, comprehensive and modular structure for assessing the energy performance of new and existing buildings (EPB) in a holistic way. It is applicable to the assessment of overall energy use of a building, by measurement or calculation, and the calculation of energy performance in terms of primary energy or other energy-related metrics. It takes into account the specific possibilities and limitations for the different applications, such as building design, new buildings 'as built', and existing buildings in the use phase as well as renovation. NOTE Table 1 in the Introduction shows the relative position of ISO 52000-1:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1:2017.
