In 2023, Princeton researchers tested a naturally ventilated cooling box; it stayed below outdoor air while using radiative cooling and buoyancy-driven airflow

Researchers have unveiled a groundbreaking cooling technique designed for buildings that eliminates the need for traditional air conditioning. This innovative approach combines a radiative cooling roof with natural airflow to keep the prototype structure comfortable and airy throughout the day. This advancement resolves the age-old challenge of balancing fresh air intake with passive cooling. However, further exploration is essential to translate this physics-driven solution into real-world applications.
