The use of the CEN ENISO EPBD

The use of the CEN & ENISO EPBD standards and the further development in CEN and ISO. Jaap Hogeling Director ISSO, Dutch building services knowledge centre Chair CEN TC 371 Program Committee on EPBD Partner in the EU CENSE project Contract: EIE/07/069/SI 2. 466698 Duration: October 2007 – March 2010 Also contributing to the BUILP UP project 09 -12 -2009 REHVA Supporters Seminar

The EPBD standards has been prepared by the CEN TC’s: CEN/TC 89 Thermal performance of buildings and building components n CEN/TC 156 Ventilation for buildings n CEN/TC 169 Light and lighting n CEN/TC 228 Heating systems in buildings n CEN/TC 247 Building automation, controls and building management This work is coordinated by: n CEN-TC 371 Programme Committee on EPBD ( the former CEN BT TF 173 on EPBD) n Brussels 9 -12 -2009 j. hogeling@isso. nl 2

CEN experience n n n The use in the EU MS’s 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 2 nd generation of CEN standards on EP of buildings Brussels 9 -12 -2009 j. hogeling@isso. nl 8

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 / “in a practical way’ n Example (next page) n Brussels 9 -12 -2009 j. hogeling@isso. nl 10

Desirable situation On CEN standards to support the EPBD Brussels 9 -12 -2009 j. hogeling@isso. nl 12

On structure of the standards n n 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) Brussels 9 -12 -2009 j. hogeling@isso. nl 13

Standards providing input for the energy performance assessment and standards on boundary conditions n On building and system components ( 7 ) n On boundary conditions (climate, indoor cond…) n Action JWG: ¨ This need to be identified as such (standards, work items, gaps) ¨ Requirements need to be specified on these, e. g. : n n 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 Brussels 9 -12 -2009 j. hogeling@isso. nl 14

EN-ISO standards: aim is to develop global standards n n n 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 lead Note: Several of the CEN standards to support the EPBD are already EN ISO standards, mainly under ISO TC 163. See N 06, annex A ¨ Within CEN: CEN standards not voluntary: national standards in conflict or overlapping have to be withdrawn ¨ Brussels 9 -12 -2009 j. hogeling@isso. nl 15

ISO-TC 163 and 205 will coordinate their work in this field n n n The JWG of TC 163 -205 was established 1 st meeting of the JWG "Energy performance of buildings using holistic approach", at ISO in Geneva on 8 th June 2009, 2 nd meeting Nov. 16 in Kyoto (ISO TC 205) Next meeting in combination with ISO TC 163 around the 7 th June 2010, Seoul, Republic of Korea Task Groups have been formed.
