« Valoriser son bâtiment avec une serre en toiture, c'est possible : le projet GROOF vous répond »

Capter l’énergie perdue des bâtiments et l’utiliser pour faire croître des végétaux dans des serres placées sur les toits de la ville, ça vous parle ? C’est l’objectif du projet européen GROOF (Greenhouses to reduce CO2 on Roofs). Tout en relocalisant une partie de la production alimentaire, l’économie d’énergie réalisée permet de limiter l’impact carbone du bâtiment et de la serre.
