RE2020 Thermal Study
Nice, PACA

In Nice, the H3 coastal climate and the value of high-end hotel and residential developments place summer comfort and envelope performance at the heart of the RE2020. On façades heavily exposed to the sun and to marine reflection, dynamic thermal simulation optimises solar shading, thermal inertia and night-time over-ventilation to hold the degree-hours threshold without systematically resorting to air conditioning. The requirements of the metropolitan local plan (PLU) and the density of Nice's building fabric reinforce the value of a thermal study conducted early. We produce the RE2020 calculation, the STD, the ACV carbon component and the Bbio and completion certificates.

Summer comfort is the sticking point of the RE2020 in Nice: 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.
