The radiation cooling material "SPACECOOL" has been newly adopted at QTnet's communication building, reducing the internal temperature by up to 5.3°C and allowing for an increase of up to 4°C in the air conditioning set temperature, thereby reducing power consumption.

SPACECOOL Inc., which develops and sells the radiative cooling material "SPACECOOL," is pleased to announce that this material has been newly adopted in communication facilities owned by QTnet, a company engaged in telecommunications in the Kyushu region, with construction set to be completed at 16 communication facilities by July 2024. This marks the first adoption of this material in the information and communication industry based in the Kyushu region.
Previously, QTnet experienced issues during the summer when sunlight entered through the ceilings of communication facilities, causing internal temperatures to rise and triggering temperature rise alerts frequently. Additionally, the internal temperatures exceeded the air conditioning settings significantly, leading to increased power consumption, prompting the search for a solution.
To address the rise in internal temperatures, the material was tested on the entire surface of the facilities, resulting in a maximum internal temperature reduction of 5.3°C and an average reduction of 3.6°C. This allowed for an increase in the air conditioning setting by up to 4°C, contributing to reduced power consumption, which led to its adoption.
