Coming Out

The approach to sustainable development that we developed had to be global. We found synthesis solutions that generate, within the framework of a controlled economy, synergy effects coming within the scope of a set of technical and architectural resolutions that are based on what we consider as the inescapable fundamentals of an environmental conception of housing: Integration of the project in its immediate environment Realisation of a successful frame as far as thermic energy is concerned A healthy building A thrifty and comfortable building For our operation in Bonne's urban development zone (in French 'ZAC de Bonne'), SKIN WALL, we reached the following objectives: Reduced service charges for the users-to-be: - 50 KWH/m2 ha./year for the heating, to compare to 90 KWH/m2 ha./year that are the present regulation, - 20 KWH/m2 ha./year for sanitary warm water, instead of 40 KWH/m2 ha./year, - 15 KWH/m2 ha./year for electricity instead of 46 KWH/m2 ha./year Successful facilities : - Solar panels - GTA with double-flow - Co-generation - Double windows - Insulation from the outside Sustainable implementation of materials. 'Thermos' buildings insulated from the outside: - Limited penetration points = outside passageways, balconies on metallic framework - Limitation of thermic bridges by suppression of acroters - Outside services : compactness of warmed surfaces - Thin watertight membrane Three distinct entities that enable to : - Identify entrance halls of the three programmes splitting them up into tree distinct streets - Create architectural entities at human's level - Make the South light get into the garden through the empty spaces laid out between the three entities - Reveal the common garden inside the block to Maginot Street, creating a central entity garden - Rationalize cells and simplify structure - Create individual terraced gardens An outside service to : - Isolate the apartments from the common parts and provide the compactness of warmed surfaces - Access to each apartment by a private terrace, hanged up among vegetation - Identify that the apartment are all individual entities - Create a 'buffer-space' between public and private A solar filter system on the East-South-West facades : - Outside circulation planted with tree on South façade - Balconies on East and West facades for summer sun - Vegetable filter on East and West facades 69 'crossing' apartments: - 100% of totally crossing apartments - Double facing North/South - Thermic comfort in summer and winter - Lightening of the apartments
