- Contract EIE/07/069/SI2.466698 Duration October
2007 March 2010 - Also contributing to the BUILP UP project
2The EPBD standards has been prepared by the CEN
TCs
- CEN/TC 89 Thermal performance of buildings and
building components - CEN/TC 156 Ventilation for buildings
- CEN/TC 169 Light and lighting
- CEN/TC 228 Heating systems in buildings
- CEN/TC 247 Building automation, controls and
building management - This work is coordinated by
- CEN-TC 371 Programme Committee on EPBD ( the
former CEN BT TF 173 on EPBD)

8CEN experience
- The use in the EU MSs of some standards is up to
80, but not all, some standards around 50. And
growing. - More information available from European CENSE
project (Oct. 2007-March 2010) - Also in CENSE feed back on actual use ?
recommendations for 2nd generation of CEN
standards on EP of buildings
9Examples www.iee-cense.eu
10Need to improve the structure of the CEN (and EN
ISO) standards
- CEN experience many countries use CEN standards
but not always as they are / - in a practical way
- Example (next page)
11Actual situation in many EU Member States On CEN
standards to support the EPBD
12Desirable situation On CEN standards to support
the EPBD
13On 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)
14Standards 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
15 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
16ISO-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 TGs is open those
interested are invited to contact the TG leaders
and their national standards body.
