The five ‘overarching’ EPB standards ISO 52000-1, 52003-1, 52010-1, 52016-1 and 52018-1 have in common that each of these describes an important step in the assessment of the Energy Performance of Buildings.
ISO 52000-1 is the overarching Energy Performance of Buildings (EPB) standard, providing the general framework of the EPB assessment. It 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.
ISO 52003-1 provides general insight on how to make good use of the outputs of the set of EPB assessment standards for different purposes (post-processing) in the form of overall and partial EPB indicators.
ISO 52010-1 contains procedures to assess the climatic data needed as common input or boundary condition for many elements in the energy calculations. For instance, as input for energy and daylighting calculations, for building elements (such as roofs, facades and windows) and for components of technical building systems (such as thermal solar collectors, PV panels). But also as boundary condition for the performance of specific heating, cooling and ventilation systems.
ISO 52016-1 provides the procedures to calculate the internal temperatures and energy needs for heating and cooling for the building as such.
ISO 52018-1 provides an overview of options of indicators enabling (optional) specific EPB requirements (post-processing) at the level of the building as such (building energy needs or building fabric).
