The European Commission asked CEN (mandate M480) to develop standards supporting the application of recast EPBD.

This overview is presented to illustrate the list of EPB standards currently out for Formal Vote at CEN and ISO level[1]. For most of the standards this final voting will close before the end of January 2017. Voting takes place through the National Standard Bodies (NSB’s). Formal Vote implies that NSB’s can only accept or not, editorial issues may be reported but technical changes are not possible. If the standard was earlier accepted in the enquiry stage, a similar positive vote in this Formal Vote stage is expected as well. These final vote versions are based on the draft standards (the prEN’s) that have been published for enquiry last year. As all comments received during the enquiry have been processed properly it is expected that the outcome of this final vote will be positive. However, it is imperative that all NSB’s really cast their votes in due time!

After the positive voting outcome, the NSB’s will have the task, during the first months of 2017, to publish these standards. For the CEN members, this also implies that they have to consider to withdraw the conflicting national standards.

Publishing these standards by the NSB’s could just include adding a national coversheet where they have the opportunity to include some national information on the role of this standard in the national regulation. Another most important task is to consider if a National Annex A is needed in case the informative default Annex B values and choices are not expected to be applicable. These national Annexes A could be different for different applications such as new buildings and existing buildings and/or different for different building categories (functions) like residential and non-residential. It is expected that the NSB’s will publish these national annexes if needed. Given the situation that it may include various stake holders reaching consensus on these values and choices, also taking into account regulator issues, it is expected to require some time to produce these national Annexes if needed.

The set of EPB Standards

To calculate the energy need and energy use of a building with its installations you need to determine:

  • The heat gain: how much free heat by solar and other internal gains (Plug loads, lighting etc.) is entering the building;
  • Building properties: The thermal properties of the building envelope and materials of all building elements;
  • External climate: the climatic data such as temperatures, humidity, solar data, location/ orientation of the building etc.;
  • Indoor environment: the indoor environmental requirements (IEQ) like indoor temperatures, humidity, ventilation rate, lighting and the related assumptions for the user behaviour (schedules for presence and usages).

These input date are the basis for the energy need calculation.

To satisfy the energy needs, the building systems for heating, cooling, humidification, dehumidification, ventilation, domestic hot water and lighting have to provide these IEQ conditions in the most energy efficient way. These calculations are included in the standards related to these systems where the EPB standards related to Building Automation, Controls and Building Management play an important role in reaching the assumed set points.
