Energy-intensive building

Following the triple HQE Exceptional, Outstanding BREEAM and LEED Platinum, the renovation of Challenger, headquarters of Bouygues Construction, which opened its doors in 1988, aims to divide by ten primary energy consumption (from 310 to 31 kWhep / m² / year), while improving the working environment and the comfort of 3400 employees.

The city of the future will consist of existing buildings renovated more than new construction. Bouygues Construction has requested through this renovation project complete expose its expertise in this field and test across one the latest innovations from its R & D programs

After the renovation of Challenger in 2014, the site will have more than 21,500 m² of photovoltaic panels that will provide nearly 2,000 MWh of electricity per year, or about 40% of its needs. During periods of the year when production will exceed consumption site, electricity will be sold. Storage solutions for photovoltaic power are also tested.

The consumption across a building or a neighborhood, is a workable solution for the city of the future as it responds in part to the problem of saturation may encounter grids during peak consumption and thus could avoid costly work of resizing networks.

Station phytoremediation retirement all wastewater and water valve Challenger, about 125 m3 per day. The recycled water naturally, thanks to the filtering action of plants and micro-organisms growing around the roots is then reused for irrigation of green spaces. Stormwater is also treated through a specific basin and reused to supply sanitary station and car washing adiabatic cooling. Challenger retirement and locally throughout its waters, with no release into the public sewer, and reduces water consumption city 40%, from 46 700 to 28 000 m3. Composed of wetlands, the resort phytoremediation fits into the 30 hectares of Challenger and contributes to the development of local biodiversity.

SUB Award 2013: this building contribution to the "city of the future"

  • Renovated an existing building that has seen its consommaiton energy divided by 10.
  • The local energy production, consumption and for eventual participation in building the balance of local power grid.
  • Reprocessing local sewage diminusr to 40% water consumption.

Sustainable development approach of the project owner

Bouygues Construction wanted, through the renovation of its headquarters, to perform a showcase for its expertise in the field of sustainable renovation. The objective was to increase its energy and environmental performance to bring it to the very best today, including new construction. All technical solutions have been proposed to divide by ten primary energy consumption, and only the most successful have been retained: 24 000 m² of replacement double glazing in a naturally ventilated double skin wall, installation of 21,500 m² 420 m² photovoltaic panels and solar thermal panels, installation of 75 probes and dry on a geothermal doublet ground water ... Challenger becomes a laboratory study of new technologies for R & D teams of Bouygues Construction.

Architectural description

Challenger consists of a main building divided into four wings, connected to a central atrium, and two triangular buildings. Entourré a park of 30 hectares, accounting for 67 Challenger 000 m² of floor space. The renovation project is conducted with the strong desire to make "Challenger Challenger rest." The architecture is fully respected.

Urban environment

    Challenger is located in Guyancourt, is about thirty kilometers south-west of Paris. To facilitate access to the site by public transport, shuttle was set up morning and evening between the site and the station of Saint-Quentin-en-Yvelines, which is used by about 10% of employees. Locker rooms with showers and lockers were also installed for employees wishing to come by bicycle and electric bikes are available, in particular to make the trip to the sports center located at Bouygues Construction proximitéres Challenger.

    Description of need: Challenger thermal regulation is provided with a water loop 250 m3, which feed clmatiseurs DRV installed in technical rooms on each floor of the buildings. Belimo valve coupled to the DRV air conditioner regulates water consumption according to its needs, thus reducing the power consumption of the pumps circulating the water in the thermal loop.

Indoor Air quality

    Measurements were performed at the reception of the work to determine the concentration of various pollutants in the building. These measures help to ensure that minimum levels required are well respected and verify compliance with comfort parameters for future occupants. The results of these measures have been successful since all measurements are consistent.
