RE2020 Thermal Study in Grenoble.

In Grenoble, in climate zone H1c, the RE2020 must reconcile cold winters and very hot summers amplified by the basin effect: real heating demand and critical summer comfort coexist. Dynamic thermal simulation sizes thermal inertia, solar shading and night-time over-ventilation to hold the degree-hours threshold, and the carbon component steers the choice of materials, including bio-based ones. We support Grenoble 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 Grenoble: 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 Grenoble

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 Grenoble 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 Grenoble and its department.
