Radiative cooling material 'SPACECOOL' that cools with zero energy reduces power consumption in communication facilities by up to approximately 10%, significantly lowering running costs.

SPACECOOL Inc., which develops and sells the radiative cooling material "SPACECOOL," announces that SPACECOOL has been implemented in the communication facilities of QTnet, Inc., which operates telecommunications services in the Kyushu region, resulting in a power usage reduction effect of approximately 10%.
QTnet has faced challenges such as alerts triggered by temperature increases inside the communication facilities during the summer and rising air conditioning power consumption. Previously, measures were taken using heat-reflective paint, but SPACECOOL was experimentally introduced on the roofs and all sides of some communication facilities. As a result, it was confirmed that the internal temperature of the communication facilities could be reduced by up to 5.3°C, leading to its implementation in 16 communication facilities.
Effect of power usage reduction
Since the introduction of SPACECOOL on September 15, 2023, the effects of power usage reduction have become evident, particularly during the months of April to August when temperatures rise, with a maximum reduction rate of 10.3% confirmed in July, especially on days with high solar radiation.
