WebCooling by a transfer of heat by radiation from the plants to the cooler night sky was inhibited. This was possible only in the "open" experiments of 1931-1934 in Petersham (Pkaes 5 and 6). Under the Môller house in the 1930 experiments (Plates 3, 4 and 5) the glass roof would prevent radia- tional cooling of the plants outside the water-filter. WebPassive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption.
