SYMBIOSIS OF FORM AND FUNCTION

Multi-Family

Design and cost efficiency are not mutually exclusive. The Safran residence, a 48-unit residence in Ouistreham, Normandy, has become a flagship project. CB Architectes have built an e4 house that is visually striking yet blends harmoniously with its surroundings through the use of terracotta bricks.

The goal was to meet all the requirements of a modern brick house construction at an affordable cost, taking full account of maximum living comfort and healthy living. This goal was clearly achieved with the building being the first project to be awarded the BEPOS effinergie 2017 label by the French association EFFINERGIE. France is not only a pioneer in climate protection, but also a country in which perfect design is much appreciated. With this showpiece, CB Architectes highlighted their skills and achieved a symbiosis of form and function, creating a very compact ensemble with a clearly-structured façade accentuating the building’s character with its corners and edges.

A streamlined result
The building made with Porotherm GF R20 bricks was additionally insulated from the inside with expanded polystyrene. The 20 cm thick Wienerberger terracotta brick offers four times more insulation than conventional brickwork and is an economical construction solution. In order to comprehensively combat heat loss, the roofs were fitted with 32 cm glass wool insulation and the ceilings on the various floors were insulated with 5 to 10 cm expanded polystyrene. The windows mainly face the south and feature high-performance double glazing. The high level of energy efficiency achieved this way is also manifested in the low operating costs. In order to improve the indoor air quality, a mechanical ventilation system was installed in each residential unit, which is automatically controlled by the humidity in the respective living space.

Self-sufficiency on a new level
Individual condensing gas boilers provide heat and water heating. In addition, more than 540 m2 of photovoltaic modules with peak outputs of 45.5 kWp and 41.6 kWp were installed on the roofs of the two buildings, which can cover energy requirements. A house that sustains itself with renewable energy – ready for the future.
