In this paper, we present results from a world-first radiant cooling
pavilion, demonstrating a method of cooling people without cooling the
air. Instead, surfaces are chilled and thermal radiation is used to keep
people cool. A thermally-transparent membrane is used to prevent
unwanted air cooling and condensation, a required precursor to deploying
radiant cooling panels without humidity control in tropical
environments. The results from this thermal comfort study demonstrate
the ability to keep people comfortable with radiation in warm air, a
paradigm shifting approach to thermal comfort that may help curb global
cooling demand projections.
