Researchers at Washington State University (WSU) have devised a solar-powered test chamber with battery storage, enabling year-round validation of cooling systems in a controlled environment.
The facility maintains a consistent 51–54°C and allows for accurate measurement of temperature, humidity, and air velocity. Its calibration was conducted based on the results of a full-scale experiment on a passive downdraft building cooling system in Phoenix, Arizona, where hot and dry conditions prevail.
Buildings are responsible for approximately 60 per cent of the world’s electricity consumption, with around a fifth of that energy dedicated to cooling.
