As per a new directive, the eu will certify buildings for energy efficiency from 2006 onwards. The European Climate Change Programme, established in 2000 to meet Kyoto Protocol targets, has identified the construction sector as providing the largest potential for carbon dioxide emission reduction.
Buildings already account for up to 40 per cent of the eu's energy consumption. And southern European countries are buying more air-conditioning units, further disturbing the energy balance.
New projects will have to install a decentralised energy supply system based on renewable energy. Existing structures will have to modernise their energy installations, and large public buildings display their certificate to the public.
