The “Parc Saurupt”, the first Schöck breakers in France

With its simple and classic architecture, the corner building in R + 3 remains discreet in this quiet residential area with houses of style from the past century. However at the time of its construction, it represented a real small revolution in the building industry since it was one of the first in France to be equipped with thermal bridge breakers. The contracting authority Nouvel Habitat wishing to take advantage of EDF's Vivrélec offer for any building that is better insulated than the basic thermal regulations, RT 1989, the Pouget Consultants thermal engineering office was asked for its expertise in this area. . André Pouget recommended the installation of Schöck thermal bridge breakers. This first collaboration between this specifier and the inventor and developer of breakers gave birth to a real partnership which is still current, it is also the first housing project of Schöck in France. A successful bet for both parties!

The installation of a switch improved the energy balance of the building by 10% and thus went from an overall loss coefficient Gv -10% to Gv -20%, opening the right to the Vivrélec offer which took into account charges the investment linked to the supply and installs breakers. "Without this breaker, we would have had to settle for a reduction of only 10% in heat loss" said Charles Bottger, director of the design office of the shell company Saee-Ramelli. The Schöck breakers were placed at the slab / facade, slab / balcony and split / facade connections in this interior insulated building. The audacity of the client and the thermal engineering office to bet on this technology, which was very little known on the market at the time, was rewarded by obtaining the Promotelec label. “Thanks to this experience at Parc Saurupt, we became aware of the need to treat thermal bridges in buildings. Without this, RT 2012 would never have imposed ψ 9 guaranteeing that the average linear thermal transmission coefficient of the intermediate floor / wall connections does not exceed 0.6W / (ml.K) Explains André Pouget.

The inhabitants of housing ranging from a simple studio to a duplex F5 therefore settled in April 1999 in energy-efficient housing. The windows facing North and East have low-emission glazing, high-performance humidity-sensitive ventilation of type B and Vivrélec electric heating with a system of convectors and radiant panels have been installed. The added value of the breakers on the energy bill was put forward when the apartments were sold and the inhabitants were able to quickly have proof of this. For the 5 m² F180 accommodation with a large picture window opening onto a terrace, the first electricity bill amounted to nearly 1500 euros, a little less than half of which for heating. The distribution is even less in the T2 below and in general we could assess at the time at 25 francs / m², or 3,81 euros, the cost of heating in such accommodation. The circuit breakers limited heat loss and the consumption of housing was therefore reduced.
