Which stakeholders were involved in the development of the set of EPB standards and how do they take into account the feedback from the market?
The responsible ISO and CEN technical committees (TCs) have working groups (WGs) where the technical experts are cooperating to prepare new standards or revise existing standards. The technical experts are nominated by the National Standards Bodies (NSBs), the CEN/ISO members. The background of these experts is very diverse: designers, industry, practitioners (dealing with system or […]
How can EU Member States follow the template of Annex A of a given EPB standard to describe their national calculation procedures (acc. to EPBD:2018, Annex 1) if their national calculation procedures are different?
According to EPBD:2018, Annex 1, when EPB standards are not adopted in full by a EU Member State, then the Annex A of the standard should be used as a template to describe the national calculation methodology and national choices, ensuring compliance with the EPBD. If a Member State is able to use the normative […]
Each ISO standard is relevant at global level, including Europe. So why are the EPB standards that have been prepared in collaboration between ISO and CEN, published as combined European (CEN) and global international (ISO) standards and not simply published as ISO standards?
By preparing the standard as a combined CEN and ISO standard, the final draft standard is subjected to parallel voting: by the ISO members to approve publication as an ISO standard, and by the CEN members to approve it as a CEN standard. If the final draft is approved in ISO, but rejected in CEN, […]
Do the EPB standards go beyond a single building, such as networks? Do they cover demand-side flexibility?
First of all, (EN) ISO 52000-1, the overarching EPB standard, introduces the term “building portfolio”: a set of buildings and common technical building systems whose energy performance is determined taking into account their mutual interactions. An example of common technical systems is an energy generation system (PV panels, wind turbine, cogeneration unit, boiler, etc.) serving […]
The template for national choices (Annex A in each EPB standard) is mandatory. Does this mean that all tables shall be filled in always?
If (a part of) a table in Annex A of the EPB standard is not applicable due to national choices that are in line with the standard, the corresponding (part of) the table in the National Annex or National Datasheet may be left blanc. It is strongly advised be stated explicitly why (the part of) […]
Is it correct that the set of EPB standards is mainly relevant for Europe?
No. The set of EPB standards was originally initiated by the European Commission for support the Energy Performance of Buildings Directive (EPBD). The set of EPB standards is of equal relevance at global (ISO) level. As a matter of fact, already one third of the EPB standards, for instance the overarching EPB standard (EN ISO […]
Why is the calculation of the overall energy performance of a building split into separate EPB standards?
Why is the calculation of the overall energy performance of a building split into separate EPB standards and not combined into an all-in-one standard (at least all EPB standards that are part of the overall EP calculation)? In general, the ISO and CEN standards making process is handled by various technical committees or TCs as […]
Are all National Annexes and National Datasheets publicly available?
A National Annex is filled in and published by a National Standards Body (NSB), as annex to the national implementation of the EPB standard. The NSB can choose to publish this stapled to the standard, or as separate document(s). Consequently, it is publicly available, but it may not be available for free. A National Datasheet […]
Where can I ask questions or submit comments if something is unclear or maybe wrong in one of the EPB standards under this topic?
Please contact us if you have a question or comment on one of the EPB standards… In general, the National Standard Body can be contacted for information and comments on any CEN or ISO standard. A list of National Standards Bodies can be found here. Specifically for the EPB standards: Part of the services of […]
Will the EPB standards provide guidance for collecting input data for use in the calculations, e.g. a complete list of input parameters?
Yes, each EPB standard has a list of all input and output data. Also, in each of the spreadsheets that are available <link> you can find the list of input parameters for the associated EPB standard. The challenge, however, is to see through these “blunt” lists of input data. You could easily say that the […]
