A calculation methodology based on European standards makes it possible to harmonise the various measures for improved energy efficiency in buildings across Member States. A common methodology increases the accessibility, transparency, comparability and objectivity of energy performance certification, as recommended in the Energy Performance of Buildings Directive (EPBD).

What is happening with CEN standards?
The use of European standards for calculating energy performance (and for energy performance certification, and the inspection of heating systems and boilers, ventilation and air-conditioning systems) will increase the accessibility, transparency, comparability and objectivity of energy performance certification across the Member States and reduce costs compared to developing separate standards at national level. At the same time, to facilitate implementation of the EPBD and the setting of energy performance requirements by the Member States, the standards should be flexible enough to allow for necessary national and regional differentiation. This combination is a challenge that called for a follow-up on the first set of CEN standards to support the EPBD (2007-2008).
The work to prepare a second generation of CEN standards, in support of the recast EPBD, started a few months ago with a new mandate from the European Commission to CEN (M/480). The leading CEN experts use the BUILD UP tools for communicating latest developments of their work and progress to the general public.
In the dedicated BUILD UP community Energy performance calculation procedures and CEN standards (http://www.buildup.eu/communities/epcalc) we present information on the standardisation process: the goals, work plan, specific discussion items and interim results. This is key, digestible information for policy makers, building professionals, educators and standards writers.
Join the community now to engage with the rapid and very interesting developments.
For starters, familiarise yourself with the territory and check out:
- Concise information papers on the published ‘first generation’ of CEN-EPBD standards, such as the EN ISO standard on energy use for heating and cooling (EN ISO 13790) http://www.buildup.eu/publications/1293, or the EN standard on overall energy use and definition of energy ratings (EN 15603) http://www.buildup.eu/publications/1894
- The final report from the European CENSE project with recommendations for the ‘second generation’ of CEN-EPBD standards
- And, of course, the new mandate from the European Commission to CEN which reflects the CENSE recommendations.
Keeping you up-to-date
Activities in the current work on ‘second generation’ of CEN standards are detailed in a series of blogs. Well worth a look:
- The CEN work plan
- The time schedule for the preparation of the second generation of CEN-EPBD standards
- A draft database with list of CEN standards potentially relevant to the EPBD
- A blog containing the list of common CEN-EPBD terms and definitions as published in April 2008 (EN TR 15615). The updating of this list of definitions is part of the work to prepare a ‘second generation’ of CEN standards to support the EPBD.
- A blog on cooperation with ISO with links to ISO overview articles and the preparation of a set of international standards on the energy performance of buildings at the ISO level.
The news section is one to watch, with regular updates such as http://www.buildup.eu/news/28546.
CEN and EPBD Communities on BUILD UP
Far from being isolated, the BUILD UP community Energy performance calculation procedures and CEN standards interacts closely with other BUILD UP communities, in particular:
