Schöck breakers for the insulation of buildings in the Fort d'Issy eco-district

AS.Architecture-Studio and Bouygues Immobilier were selected through competition for the realization of the ground plan. To ensure the low energy consumption of new buildings, in addition to effective exterior insulation, some developers have chosen to install Schöck Rutherma thermal bridge breakers.

Rewarded by the award of the “Ecopolis” Label from the Attali Commission and the 2011 Ecoquartier Prize, at the start, the challenge was nevertheless ambitious: to create an entirely eco-designed district within the walls of the old fort. It took 14 years to achieve this surprising result and it was in June 2013 that the eco-district was inaugurated. Today, after 926 days of work, there are 1623 housing units (40% of which are social housing) and 3 inhabitants spread over 500 residential buildings in a spirit of respect for the environment and the well-being of the inhabitants. .

The buildings at Fort d'Issy meet the requirements of the Low Consumption Building Label (BBC). In order to halve consumption, 78% of energy needs are provided by underfloor heating. In this sustainable district, the villas are bioclimatic which avoids energy losses: the performance of the insulation from the outside, the arrangement of the openings, the sunshine and the calculated ventilation optimize the contribution of natural elements ensuring a optimal thermal and acoustic comfort. The inhabitants are also concerned by this effort with the installation of home automation in each apartment to program the heating, the opening / closing of roller shutters and smartphones can warn of forgetting to switch off the light. Hot water and heating are produced by geothermal energy using a well dug 700 m deep. Heat pumps complete this system in each building. Equally useful, practical and ecological, the innovation of clearing household waste by pneumatic suction of some 200 containers of waste per day that they would have represented. Thus, with these innovative technologies, the buildings of Fort d'Issy only consume 65 kWh / m2 / year.

Kaufman and Broad is the developer of five of the villas whose construction was carried out by Campenon Bernard Construction (CBC), a subsidiary of the Vinci group. Schöck was chosen to install nearly 1 ml of thermal bridge breakers in the Ovelys, Alizée, Solaris and the two Ovalys villas. Each reveals an elegant and slender oval-shaped architecture that seems to play with the clouds. Schöck supplied the thermal bridge breakers for the balconies of the Belvédère building (also called “boomerang” by its shape) from the developer Bouygues Immobilier on the plans of the firm AS.Architecture-Studio and built by the prime contractor Bouygues Construction . The promoter also relied on Schöck's know-how for the insulation of its buildings Visiô, Horizon and Le Ô Paris, which are three of the old bastions of the fort rehabilitated. Bouygues Immobilier and Kaufmann and Broad design residential buildings here with thermal insulation from the outside. It offers more than satisfactory results but just shows a failure at the level of the balconies because thermal bridges are created at this junction if it is not treated. Reliable, durable and economical Schöck thermal breakers limit the amount of heat loss at thermal bridges. In this sustainable and environmentally friendly neighborhood, the use of breakers finds its place. For the entire project, Schöck supplied a total of 000 ml of K, DF, D and Q thermal breakers specially designed for balcony insulation.

Schöck is not his first project based on sustainable development. Already in 2007, the supplier contributed to the construction of the first “zero energy” school located in Limeil-Brévannes in the Val-de-Marne (94). The manufacturer did not stop there since in March 2009, the social housing of Paris Habitat became thanks to their switches, respectful of the environment and allowed the inhabitants to save on their electricity bills. With these projects already completed and the recent participation in the rehabilitation of Fort d'Issy, Schöck is therefore part of a societal and environmental approach, today and even more tomorrow.
