Construction of a residential building
"sustainable development oriented"
We've designed a compact building that's perfectly insulated, as if it had been covered with a coat that protects it in both winter and summer. It's nice inside because you're occupying it and releasing heat. If the weather is sunny, it's even better and you no longer need to heat. Of course, you need to keep the sun out in summer, to avoid overheating.
As the choice of construction system has an impact on the building's performance and its ability to regulate external climatic fluctuations such as those seen in recent years, we chose solid stone for its regulating qualities.
With a view to reducing the impact on the environment, we have given preference to locally quarried stone, such as Sireuil rock from the Cognac area (approximately 110 km from the project).
In addition to high-performance insulation of the walls, we have paid particular attention to eliminating the passage of heat through particular points in the structure that encourage heat loss. Doors and windows, which are less insulating than fixed opaque walls, have also been selected to achieve a higher level of insulation.
The promotion of our construction is based on the proven fact that the biggest impact of a building is not in its construction, but in its energy consumption over the years it is occupied.
With its economic and ecological performance, complemented by its connection to the city's district heating network, our project is fully in line with the logic of amortizing any additional construction costs well before the end of the ownership period, by offering its residents greatly reduced operating costs.
