As part of the thermal renovation of a building with 24 social dwellings, installation of a bioclimatic greenhouse on the existing roof. The idea is to test the thermal exchange between the building and the greenhouse. The greenhouse will capture heat to be used to heat domestic hot water, while the building will heat the greenhouse in the winter.
A digital forecasting tool will determine the balance between the production of kW, the temperature and the humidity of the greenhouse depending on weather conditions. This new roof space could also host the horticultural or agricultural activities organized by local stakeholders and residents of Nantes Métropole Habitat.
