The set of EPB assessment standards produces a great number of overall and partial EPB indicators as outputs. ISO 52003-1:2017 provides general insight to both private parties and public regulators (and all stakeholders involved in the regulatory process) on how to make good use of these outputs for different purposes (post-processing). ISO 52003-1:2017 describes the relation between the EPB indicators and the EPB requirements and EPB ratings, and it discusses the importance of project-specific, tailored values as requirement or reference for certain EPB indicators. ISO 52003-1:2017 also includes a couple of possible EPB labels and it lists the different steps to be taken when establishing an EPB certification scheme. ISO 52003-1:2017 provides standardized tables for reporting in a structured and transparent manner the choices that are to be made with respect to overall EPB requirements. The tables are non-restrictive, thus allowing for full regulatory flexibility. ISO 52003-1:2017 does not provide such tables for partial EPB requirements (related to the fabric or technical buildings systems), as this is dealt with in other documents. NOTE Table 1 in the Introduction shows the relative position of ISO 52003-1:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.

This International Standard applies to new buildings and is applicable to space air-conditioning equipment and the heating plant in new buildings.

ISO 16814:2008 is intended to specify methods to express the quality of indoor air suitable for human occupancy, to allow several acceptable target levels of indoor air quality, depending on local requirements, constraints and expectations. ISO 16814:2008 applies to the design of new buildings and their systems and the retrofit of existing buildings and systems, indoor environments where the major concern is that of human occupants, buildings having any combination of mechanical and natural ventilation, commercial and institutional buildings. ISO 16814:2008 does not apply to residential buildings, industrial buildings and hospitals although those parts of such buildings that are similar to commercial buildings are covered. The requirements of ISO 16814:2008 might not achieve acceptable IAQ for all people in all buildings, due to one or more of the following sources of uncertainty. The outdoor air brought into the building can be unacceptable or might not be adequately cleaned. Indoor air has a wide diversity of sources and contaminants. There are many factors that affect occupant perception and acceptance of IAQ, such as air temperature, humidity, noise, odours, lighting and psychological stress. There is a range of susceptibility and preference in the population.

It is the intention of ISO 14908-1:2011 to permit extended services (defined by users) to coexist. Certain aspects of ISO 14908-3:2011 are defined in other documents. These documents are referenced where relevant. In the case where a referenced standard conflicts with ISO 14908-3:2011, the latter will prevail.

Parameters that are controlled by other layers, but which control the operation of the physical layer, are also specified.
