Further Solar cooling Solar cooling technology has been proven to be effective and THE IEA SOLAR HEATING AND COOLING PROGRAMME The lnternational Energy Agency (1EA) was formed in 1974 as an autonomous body within !he Organization for Economic CoOperation and Development (OECD). it carries out a programme of energy co-operation, including joint research and development of new and improved energy technologies. The Solar Heating And Cooling (SHC) Programme was one of the first IEA research agreements to be established. Since 1976, its members have been collaborating to develop technologies that use the energy of the sun to heat, cool, light and power buildings. The following countries are members of this agreement: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, ltaly, Japan, Mexico, the Netherlands, New Zealand, Norway, Portugal, Spain, Sweden, Switzerland, the United Kingdom and the United States, as well as the European Commission. The mission of the SHC Programme is "to facilitate an environmentally sustainable future through the greater use of solar design and technologies". The work of the SHC Programme is unique that it is accomplished through !he international collaborative effort of experts from the Member countries. The benefits of such an approach are numerous, namely, it accelerates the pace of technology development, promotes standardization, enhances national R&D programmes, permits national specialization, and saves time and money. The work is organized into well-defined Tasks, where each country pays for its own work in the Task. This Task-sharing has proven to be effective, having positive results in countries with very different financing schemes. An Executive Committee, composed of one representative from each Member country, heads the Programme. The management of the individual Tasks is the responsibility of Operating Agents, who are elected by the Executive Committee. rPer loi agbrlaem, bmuet hi t sa su sseh oi swsn t ti l hi va et tr yh el i mt ei tcehdn.oNl oegwy dweovr ek l oi np tmh ee nItEsAi nS H C ct hoeo tl i en gc hcnyi ccal el sl i faent idm es ool ar recvoel nl e cstooor ns ebr r. i Tn gh i tsh em ep aa yn sb at ch ka tt icmoeo lwi n gi t h i n tseycsht en mo l so, gwi ei tsh atrhee i na dt hdee ds aamd vea rnat an gg ee at hsa dt os mo l ea rs tci co oh loi nt gwsayt es tr e m s sEauvr eo poen, 2p 0e 0a k1 , pZoewgeerr s( S, 2o 0u r0c0e :a An dS TI EI GA ,) .
