Overarching

The module “M1, Overarching EPB standards” comprises the EPB standards and accompanying technical reports that deal with the overall energy performance of the building.

The overarching EPB standards provide basic information needed in  the standards covered by the other modules (M2 through M11), such as common terms and symbols or common choice of climatic conditions. And/or they provide procedures how to combine information from these other modules to aggregate into the overall energy performance data, such as the overall primary energy performance.

FAQ

The revised EPBD:2018 lists in 'Annex I' five specific standards as "overarching EPB standards". Why is that list different from the list of overarching standards in the modular overview of EPB standards?
<main>

The EPBD lists five EPB standards as 'overarching'. The meaning of the terms 'overarching' in the new EPBD and in the modular structure of the set of EPB standards only partly overlap.

In the modular structure of the set of EPB standards the term overarching refers to the standards that deal with the overall energy performance of a building (module M1), while other modules deal with the building as such (M2) or with specific technical building systems or services (M3 etc.).

The five EPB standards ISO 52000-1, 52003-1, 52010-1, 52016-1 and 52018-1, listed in the revised EPBD (Annex I) and also called ‘overarching’, have in common that each of these describes an important step in the assessment of the energy performance of building.
In the modular overview of EPB standards ISO 52016-1 and 52018-1 belong to module 2 (M2, Building as such).

Indoor environmental quality

Why are there two EPB standards on indoor environmental input data: ISO 17772-1 and EN 16798-1?

EN 16798-1 has been developed by CEN/TC 156 as one of the EPB standards under the EU mandate (M/480) to CEN. It was approved and published in May 2019.

ISO 17772-1 has been developed, parallel with EN 16798-1, as an ISO document. This standard was approved and published in 2018.

Similarly, EN/TR 16798-2 and ISO/TR 17772-2 were developed in parallel, as technical reports accompanying the respective standards.

Due to collaboration between the experts in ISO and in CEN the content of the two standards is quite similar. From the beginning of the development it was decided not to opt for the preparation of a combined EN ISO standard, to decrease the risk of delays in case of unforeseen disputes. Now that the two standards have been successfully completed and published, it will be discussed in ISO and CEN (ISO/TC 163/WG4 (JWG of TC 163&TC 205) and CEN/TC 156 & CEN/TC 371) to develop a combined EN ISO standard during future revisions of the two standards.

Outdoor climate

Where can I find hourly climatic data for my region or location?

Foremost, it is up to national/regional authorities to specify which climatic data set(s) shall be used for the EPB assessment in the context of national/regional building regulations.

As default climatic data sets for any EU location, the European Commission recently supported its Joint Research Centre (JRC) to develop typical meteorological years (TMY).

A TMY is a set of meteorological data with data values for every hour in a year for a given geographical location, e.g. for calculating the energy performance of buildings.

EN ISO 52010-1 deals with the conversion of climatic data for the energy performance calculations.
An updated version of the spreadsheet for EN ISO 52010-1 is in preparation as support for users. This spreadsheet helps users with the conversion of measured hourly solar irradiation data into irradiation at a plane of any orientation and tilt angle, in accordance with EN ISO 52010-1.
The updated spreadsheet will also be able to handle TMY files from JRC’s website.

Errata in the EPB standards

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 the EPB Center is to collect presumed errors and questions on the content of EPB standards and their accompanying technical reports.

The EPB Center experts prepare, to their best knowledge, proposals for corrections and/or clarifications.
The EPB Center may communicate and publish these proposals, purely to support the implementation and application of these standards and technical reports in practice.
For such proposals the CEN/ISO commenting template will be used, to ensure an efficient communication with CEN and ISO.

In no way these proposals shall be regarded as formal corrigenda to the related CEN or ISO documents. It is up to CEN/ISO to decide upon the preparation of an amendment or revision of the document.
