A thermal performance of 45 kWhPE/m²/year comfortably met the requirements of Paris’s climate plan. The building consists of a main load-bearing structure made of reinforced concrete and a secondary timber frame structure. Both structures are covered in Tradical® Hempcrete, which makes up the infill and the in-built thermal insulation.
This homogeneous envelope benefits from everything the lime-hemp composite has to offer – moisture transfer, summer and winter thermal comfort and thermal inertia – with a very light carbon footprint to boot.
A series of thermal performance measurements for the building under real-life conditions will be taken to confirm the initial studies conducted for the project.
The behaviour of users will also be monitored to understand how facilities are actually used.
In the long term, the results will enable the efficiency of the building to be optimised and they will also be useful on future projects.
