| Bouygues Immobilier lays foundation stones of a number of projects François Bertière, Chairman and CEO of Bouygues Immobilier, the property division of France's Bouygues, has laid the foundation stone for the Bouygues Telecom Technical Centre and launched the Green Office project. Covering a combined net floor area of more than 80,000 sq. metres, these flagship projects will house 3,500 employees. The two buildings will be located at the entrance to the Meudon-la-Forêt business park outside Paris, between the Meudon forest and the N118 highway, and bordering the Vélizy 2 job zone. Designed by the architectural firm Valode et Pistre, the Bouygues Telecom Technical Centre will house the company's IT and network teams, providing it with a strategic tool for innovation. The environmental performance of the new facility was one of Bouygues Immobilier's key areas of focus. Like the future Bouygues Telecom headquarters in Issy-les-Moulineaux, the Bouygues Telecom Technical Centre is based on a High Environmental Quality (HQE ) approach with seven "very high" ratings for the HQE targets: - 60% of the building's heating requirements in winter and 100% of its domestic hot water will be produced by an energy recovery system installed in the cooling units of the computer rooms; - a metal grid on the south outer wall will act as a brise-soleil, limiting solar gain and reducing air-conditioning requirements; - light fixtures will be fitted with photoelectric cells so that luminous intensity can be varied according to the level of natural lighting; - the green spaces will be watered using a rainwater recovery system. The building is due to be delivered in September 2009. Green Office, the first large positive-energy building, was designed by Atelier 2M with the overarching principle of minimising power consumption and producing an energy surplus. Green Office will have a total floor area of 23, 300 sq. metres, half of which is earmarked for 400 Bouygues Immobilier employees. Delivery is scheduled for first-half 2010. The building's bioclimatic design and high-performance natural ventilation system will cut energy consumption to the minimum. The outer walls will be externally insulated, and air circulating fans and external blinds will provide solar protection and increased comfort in summer. Powered entirely by renewable energies, the building will generate 64 KWh/sq. metre/year compared with total consumption of 61 KWh/sq. metre/year. Green Office will consume 60% less energy than a standard building constructed to RT 2005 thermal regulations and 30% less than the most energy-efficient buildings currently on the market. Power will be produced by more than 5,000 sq. metres of solar panels installed on the outer walls and as car ports in the outdoor car parks. Green Office will also have a biomass combined heat and power system, fuelled by wood or oil, to produce heat and electricity. write your comments about the article :: © 2007 Construction News :: home page |
