In 2023, Princeton researchers tested radiative cooling with natural ventilation and thermal mass, keeping a building 3.9°C below outdoor air

In 2023, researchers tested whether a building could be cooler than the air outside while still relying on natural ventilation. The experiment used two insulated boxes in California to study how radiative cooling, thermal mass and temperature-driven airflow could work together without fans or mechanical systems. The test box had an uninsulated aluminium roof covered … Read more
