La chiesa cattolica di San Francesco a Ebmatingen, nel canton Zurigo, ha ricevuto venerdì il Premio solare europeo 2019. Costruito nel 1989, l'edificio religioso ha subito un risanamento costato 1,2 milioni di franchi, che l'ha reso esemplare sia dal profilo ecologico (a zero emissioni) che da quello energetico.
Il riscaldamento a nafta che consumava 7'000 litri all'anno ed emetteva 21 tonnellate di CO2 è stato eliminato e il fabbisogno annuo di 84'400 kWh è stato ridotto a 54'700 con una migliore isolazione del tetto, un riscaldamento a pompa di calore geotermica che funziona a energia solare, un'illuminazione LED e 161 metri quadrati di pannelli fotovoltaici.
Questi ultimi forniscono 78'900 kilowattora, così che la chiesa si ritrova a produrre molta più energia di quella che consuma.
