RE2020 Thermal Study in Nîmes.

In Nîmes, among the hottest towns in France in climate zone H3, summer comfort dominates the RE2020. Between refurbishment of the old centre and new-build developments in the Costières, dynamic thermal simulation sizes thermal inertia, solar shading and natural ventilation on a building fabric subject to strong summer overheating. The carbon component (Ic construction and Ic énergie, via ACV) steers the choice of systems and materials. We support Nîmes projects on the regulatory thermal study, the STD, summer comfort and the Bbio and completion certificates.

Summer comfort is the sticking point of the RE2020 in Nîmes: 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 Nîmes

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 Nîmes 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 Nîmes and its department.
