Tokyo Metropolitan Bureau of Transportation Begins Demonstration Test of Waterproof Sheets Using the Radiative Cooling Material “SPACECOOL”
SPACECOOL INC., Tokyo Metropolitan Bureau of Transportation, and LONSEAL CORPORATION have started a joint demonstration test of SPACECOOL waterproof sheets at the Bureau’s Shinagawa Office with the goal of reducing air-conditioning energy usage at Toei Bus offices this summer.
This is the first time that a joint demonstration of SPACECOOL waterproof sheets has been conducted in the Tokyo metropolitan area.
Background
Tokyo Metropolitan Bureau of Transportation has been facing the problem of high electricity usage at its offices from the use of air conditioners every summer.
This prompted the Bureau’s interest in SPACECOOL, a radiative cooling material capable of zero-energy cooling when placed under direct sunlight, leading to the decision to conduct a joint demonstration test at the Shinagawa Office to tackle the problem outlined above.
Overview of the demonstration test
SPACECOOL waterproof sheets will be installed on the rooftop of the Shinagawa Office, and the amount of electricity used at the office will be measured and compared with that prior to installation.
・Period: May 1st to September 30th, 2024
・Specifications of SPACECOOL waterproof sheets
S-F2 (MLIT common specification number)
PVC sheet waterproofing bonding method (10-year warranty)
Radiative Cooling Material “SPACECOOL”
SPACECOOL is a new material that not only blocks heat from sunlight and the atmosphere in direct sunlight and suppresses heat absorption, but also enables temperatures to be lower than the outside temperature with zero energy by releasing heat into space based on the principle of radiative cooling.
