the further development in CEN and ISO.

The 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)

43 (parts of) standards on EPBD have been
published in 2007/2008

• The TOP standards
• EN15603 Way of expression Energy Performance
  and CO2
• EN15217 EP certificate
• Standards on thermal property of buildings (TC89)
• Standards on heating systems (TC228)
• Standards on AC, ventilation and cooling systems,
  indoor environment (TC156)
• Standards on lighting (TC169)
• Standards on building automation and controls (TC
  247)
• Standards on inspection (TC156 228)
• The umbrella document CEN TR 15615

CEN 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

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
• Example (next page)

11
Actual situation in many EU Member States On CEN
standards to support the EPBD
12
Desirable situation On CEN standards to support
the EPBD
13
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)

14
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

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

16
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 TGs is open those
  interested are invited to contact the TG leaders
  and their national standards body.
