La Défense de l'environnement

La Défense, the business district in Paris, is well known for its superb modern architecture. There are plans for a new building, the Carpe Diem tower, which will be built to the highest environmental standards, with a green roof and surfaces covered by solar panels. The designers expect a 30% reduction in energy use.

The tower, designed by Stern Architects of New York, will have a winter garden at its base and roof garden terraces at the top. Solar panels will provide hot water and windows will be protected from the sun to reduce any necessity for air-conditioning. The building will have natural ventilation, systems for the recovery of soapy water and rain water, and low-consumption lighting.

For heating, the building will be part of the La Défense network but it's hoped that there will be little need, as a result of heat produced by computers etc. Two of the four sides of the building will be inclined in such a way as to optimise the use of natural daylight.
