passive radiative cooling

Passive radiative cooling in unventilated and ventilated enclosures (A) View of an experimental cooling container used by Trombe and his team in Mont-Louis, France, undated.23 (B) Diagrammatic vertical section of Trombe’s patented design for the cold house, 1967.24 (C) North-east view showing the radiative cooling facade of the cold house designed and built by Felix Trombe and his team in 1963–1963 in Odeillo, France.25 (D) Schematic drawing of the Skytherm system during the day with the movable insulation covering the roof (left), and during the night with the water-filled bags exposed to the cold-infrared sky (right).27 (E) Harold Hay and John I. Yellott in front of a prototype of the Skytherm system built in Pheonix, Arizona in 1967.28 (F) Schematic of our test box, reproducing 1% of the thermal loads, losses, and air changes attributable to one occupant. (G) Schematic of the proportions of the thermal mass, radiator, and ventilation openings needed for one occupant.
