A Japanese company responded to the government's call for energy conservation and laid roof cans on the roof to help reduce the temperature and achieve remarkable results. A food company that makes fish cakes in the city of Kamakura, Kanagawa Prefecture, neighboring Tokyo, in order to improve air-conditioning efficiency, this month, about 1600 abandoned cans were spread on the roof of a refrigerated warehouse to separate sunlight and lower temperatures. Eight employees spent four hours, covered half of the roof, about 15 square meters. Subsequently, these employees used a net to cover the roof to prevent wind blowing cans. The roof surface temperature dropped from 55 degrees Celsius to 36 degrees Celsius. Kyodo News quoted a supervisor of the company on the 26th, saying that basically no money is spent on collecting and laying cans, but it only takes energy, but it can turn waste into treasure. In view of the remarkable effect, it is intended to cover the entire roof with cans. This technology, developed by a large Japanese construction company, can insulate and insulate, and is suitable for both winter and summer.
