This dataset, published by the Geneva territorial information system (SITG), maps the potential for thermal energy production using vacuum-tube solar collectors for special applications, aggregated by base surface (roof slope, canopy, parking area). It accounts for well-exposed surfaces receiving sufficient solar irradiation to be suitable for vacuum-tube heat collection, distinguishing them from areas better suited to standard solar thermal or photovoltaic use. Covering the canton of Geneva, the layer supports spatial analysis of renewable heat potential for urban planning, building retrofit studies, and energy policy work related to solar thermal deployment in the region.La couche du potentiel de production de chaleur sous vide (usages spéciaux) par surface de base (pan de toiture, couvert, parking) représente et regroupe les informations relatives au potentiel de production d'énergie thermique: - tenant compte des surfaces bien exposées (qui ont une irradiation so…
