Radiative Cooling in Hot Humid Climates

Aubrey Jaffer


Passive radiative cooling of buildings is starting to be deployed as Cool Roof treatments in subtropical climates.

The greatest need for cooling is in the tropics. The high humidity endemic to many of these regions severely limits the passive cooling available per radiative area. To wrest temperature relief from humid climates, not just nocturnal cooling but daytime cooling is needed.

This project seeks to achieve daytime passive radiative cooling in the tropics by combining a novel, high performance solar screen with compound parabolic concentrators.


These pages and software are still in development. Here is the 2006 project report (PDF).
