SPACECOOL Company Overview

SPACECOOL Inc. (Headquarters: Minato-ku, Tokyo, CEO: Masahiro Suemitsu, hereinafter referred to as "the Company") is pleased to announce that our business has been awarded an A rank certification at the "Kyoto City Venture Company Evaluation Committee" hosted by Kyoto City and the Public Interest Incorporated Foundation Kyoto Advanced Technology Research Institute (ASTEM). This system aims to discover and nurture venture companies that will support the next generation of the Kyoto economy, with experts evaluating companies based on their technological capabilities, novelty of business plans, market potential, and feasibility. Business plans recognized as having a high likelihood of success are certified as "A rank." Companies with A rank certification can utilize support such as market development assistance from Kyoto City and ASTEM, and further business expansion is expected to be initiated from Kyoto. With this A rank certification as a catalyst, our company will further strengthen collaboration with domestic and international companies and research institutions, including those in Kyoto, and accelerate the social implementation of radiative cooling technology.

SPACECOOL Co., Ltd. collaborated with Professor Tomoyuki Chikamoto from Ritsumeikan University's Department of Architecture and Urban Design and the Japan Gas Association to jointly demonstrate and verify how much the outer membrane made of radiative cooling materials contributes to improving thermal conditions and reducing air conditioning energy during the summer at the "Gas Pavilion: Ghost Wonderland," which was exhibited at the Osaka-Kansai Expo. As a result, it was shown that applying radiative cooling materials could potentially reduce air conditioning energy by up to about 40% compared to conventional membrane materials. This pavilion is a membrane structure designed by Nikken Sekkei Ltd., and the Japan Gas Association adopted the radiative cooling material "SPACECOOL," developed and marketed by SPACECOOL Co., Ltd., for the entire outer membrane, in line with the concept of the Osaka-Kansai Expo as a "testing ground for future society," aiming to verify the effectiveness of new materials that achieve energy conservation. This demonstration involved temperature measurements throughout the duration of the Osaka-Kansai Expo at the Gas Pavilion, as well as verifying the impact of indoor temperature distribution and air conditioning load through computational fluid dynamics (CFD analysis).

SPACECOOL Inc. has been awarded "Best GreenTech Startup" at the Global Startup Awards (GSA) East Asia and has been selected as the regional winner for East Asia. As a result of this award, SPACECOOL will advance to the global final, representing East Asia, where regional winners from around the world will gather. The global final is scheduled to be held in May 2026 in Valletta, Malta, as part of the official program of the EU-Startups Summit, one of Europe's leading startup events. Comment from CEO Masahiro Suemitsu: The increasing demand for cooling is a critical issue in addressing energy problems and climate change. We aim to deploy passive cooling infrastructure that reduces thermal load without consuming energy on a global scale. This award reflects the importance of this challenge and the international effectiveness of our technology, and we are truly honored.
