The approach to the Lubidet project is based on a compromise between energy performance, respect for heritage and the economic constraints of construction and maintenance .
Also aimed at vulnerable people, this housing complex has been renovated in order to promote "socialization" and meetings. The central houses have been razed to allow the establishment of an efficient and innovative collective space, while a circulation gallery serves housing on the southern side. Accessibility has been thought through in detail (with in particular the complete removal of thresholds on 2T2 entrances and access to common East and West terraces). The comfort sought is different from a traditional, but real, residential building.
The architectural aspect of the existing facades has been preserved, limiting the thermal performance of the one to the south. Nevertheless, solutions have been found (lime / hemp plaster) to reduce the cold wall sensation which directly impacts on the sensation of thermal comfort and therefore of energy consumption.
Finally, the choice has been made to give priority to wood and biobased materials for a better comfort of residents with the use of wood / straw boxes, wood wool (rain cover), laminated wood and coated lime / hemp .
