CEN experience The use in the EU MS’s of some standards is up
to 80%, but not all, some standards around 50%. And growing.

Need to improve the structure of the CEN (and EN ISO) standards CEN experience: many countries use CEN
standards but not always as they are /

On structure of the standards How to ensure that the standards can be used
as such by the countries (referred to in the national building regulations)?
E.g. by making in each standard a clear distinction between: General part Part with options (A, B, C..) to be selected at national
level for a specific application Part with national input (and optionally: default input
values provided)
[email protected] 14 Brussels 9-12-2009
Standards providing input for the energy performance assessment and standards on boundary conditions On building and system components ( 7 ) On boundary conditions (climate, indoor cond…) Action JWG:
This need to be identified as such (standards, work items, gaps)
Requirements need to be specified on these, e.g.: The output variables: consistency in (or conversion of) used
terms, definitions and symbols Type of output: fit for use in annual calculations? Monthly?
Hourly? Application range (e.g. types of bldg, new/existing
bldng/systems, Fit for use in context of building regulations

EN-ISO standards: aim is to develop global standards
vital: ISO standards also applicable to CEN, for use in context of Energy Performance of Buildings Directive (EPBD)
for CEN: existing set of CEN standards (published 2007-2008) will be replaced by revised standards, developed as EN ISO standards under Vienna agreement between CEN and ISO
This is very important, because this will involve acceptance from different CEN Technical Committees (CEN TC 89, TC 156, TC 228, TC 247, TC 169) that ISO takes the leadNote: Several of the CEN standards to support the EPBD are already EN
ISO standards, mainly under ISO TC 163. See N06, annex A Within CEN: CEN standards not voluntary: national standards in
conflict or overlapping have to be withdrawn

ISO-TC 163 and 205 will coordinate their work in this field The JWG of TC163-205 was established 1st meeting of the JWG "Energy performance of
buildings using holistic approach", at ISO in Geneva on 8th June 2009,
2nd meeting Nov. 16 in Kyoto (ISO TC 205) Next meeting in combination with ISO TC 163 around
the 7th June 2010, Seoul, Republic of Korea Task Groups have been formed. The participation to the TG’s is open: those interested
are invited to contact the TG leaders and their national standards body.
