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.

ISO/TR 16344:2012 provides a coherent set of terms, definitions and symbols for concepts and physical quantities related to the overall energy performance of buildings and its components, including definitions of system boundaries, to be used in all standards elaborated within ISO on energy performance of buildings. These terms and definitions are applicable to energy calculations in accordance with the Technical Report and standards on the overall energy performance of buildings and their components, to provide input to the Technical Report or using output from the Technical Report. They are based on existing terms and definitions from standards and other documents referenced in the bibliography.
ISO 16346:2013 defines the general procedures to assess the energy performance of buildings, including technical building systems, and defines the different types of ratings, and the building boundaries. The purpose of ISO 16346:2013 is to a) collate results from other International Standards that calculate energy use for specific services within a building, b) account for energy generated in the building, some of which may be exported for use elsewhere, c) present a summary of the overall energy use of the building in tabular form, d) provide energy ratings based on primary energy, carbon dioxide emission, or other parameters defined by a national energy policy, and e) establish general principles for the calculation of primary energy factors and carbon dioxide emission coefficients. ISO 16346:2013 defines the energy services to be taken into account for setting energy performance ratings for planned and existing buildings and provides for 1) a method to compute the standard calculated energy rating, a standard energy use that does not depend on occupant behaviour, actual weather, and other actual (environment or indoor) conditions, 2) a method to assess the measured energy rating, based on the delivered and exported energy, 3) a method to improve confidence in the building calculation model by comparison with actual energy use, and 4) a method to assess the energy effectiveness of possible improvements. ISO 16346:2013 is applicable to a part of a building (e.g. flat), a whole building, or several buildings.
