RE2020 Thermal Study in Marseille.

In Marseille, in climate zone H3, the RE2020 is decided first and foremost on summer comfort: the glazed commercial floorplates of Euroméditerranée and dwellings facing south-west quickly reach the regulatory degree-hours threshold. Dynamic thermal simulation makes it possible to arbitrate between thermal inertia, solar shading, brise-soleil and cross-ventilation before fixing the envelope. Added to this are the carbon thresholds (Ic construction, Ic énergie) which, in a dense sector, steer the choices of structure and bio-based materials. We carry out the RE2020 regulatory calculation, the STD and dynamic ACV for Marseille projects, from the planning application to the completion certificate.

Summer comfort is the sticking point of the RE2020 in Marseille: on exposed façades, the degree-hours (DH) threshold is quickly exceeded, all the more so in the south of France. Dynamic thermal simulation arbitrates between thermal inertia, solar shading and natural ventilation before the building envelope is fixed.

FAQ

FAQ, re2020 thermal study in Marseille

Summer comfort is one of the sticking points of the RE2020, particularly in the south of France: the degree-hours (DH) indicator is decisive there and the upper threshold (1,250 DH) is quickly reached without solar shading, thermal inertia and night-time ventilation. We verify it through dynamic thermal simulation (STD) from the design stage in Marseille to avoid non-compliance at the end of the project.
Yes: RE2020 regulatory calculation (Bbio, Cep, Cep,nr, Ic construction / Ic énergie carbon indicators via dynamic ACV) using the TH-BCE engine, Bbio certificate to be filed with the planning permission and compliance certificate at completion. We cover residential and commercial buildings in Marseille and its department.
