Radiative cooling is a phenomenon that occurs every day on Earth that emits heat into space. We have succeeded in developing a sheet-like material that efficiently generates this principle. Although we have only been in business for less than three years, we have exhibited at the COP28 Japan booth, received the Minister of Land, Infrastructure, Transport and Tourism Award at EcoPro23, and are working to promote the use of the SPACECOOL radiant cooling material. We are working to spread the use of SPACECOOL, a radiant cooling material.
