At regular intervals the magazine of the international Organization for Standardization ISO, Focus+ (previously: Focus) contains an article on the work in ISO on energy performance of buildings.
For instance, see:
- Pages 22-26 in September 2009 issue of ISO Focus
- Pages 24-26 in May 2011 issue of ISO Focus+
A new article is currently in preparation.
Concerning cooperation between CEN and ISO on energy performance of buildings:
For the CEN work, co-operation with the relevant ISO groups is important, with as preferred outcome the publication of combined EN-ISO standards.
Of course, the cooperation should not jeopardise the European targets. However, there is a wide experience in cooperation and in ways to accommodate differences where needed. Many of the first set of CEN-EPBD standards are already combined CEN ISO standard. For instance one of the key EPBD standards, EN ISO 13790:2008 (energy use for heating and cooling), and the whole suite of thermal transmission standards (ISO/TC 163 and CEN/TC 89).
Now that the first drafts of the current CEN work are becoming available within CEN (see timetable), the possibilities to strengthen the cooperation are being explored and discussed.
This co-operation aims to avoid serious duplication of work, to avoid incompatibilities in (input) product data, procedures and (output) energy performance data.
ISO is highly interested in using the CEN-EPBD standards as basis for international standardisation on the energy performance of buildings.
The central co-ordination of the preparation of a set of international standards on the energy performance of buildings at the ISO level is in the hands of ISO /TC 163/WG 4 (Joint Working Group of ISO TC 163 and TC 205 on energy performance of buildings using a holistic approach). The main leading and active experts in CEN are among the main leading and active member of the ISO Joint Working Group.
Cooperation would also avoid (or at least diminish the risk) that –for the same topics- one part of the world develops and uses CEN standards, and another part of the world develops and uses different and diverging ISO standards.
