Cooling experiments performed with test modules at the Passive Test Facility at Trinity University during 1981 are described. Two modules were used: a four foot square roof pond module, which was operated in parallel with a full size test building, and a four foot by eight foot trickle roof module. Four experiments were performed on the pond module. Dry bag experiments were carried out from July 14 to October 16 in order to compare the heat loss rate of the module to that of the full scale houses. Flooded bag experiments were conducted on October 26 and October 30 through November 6. The bag was flooded wth approximately 1 in. of water. Open pond experiments were performed from November 6 through November 9 in order to determine evaporative loss. Parapet experiments were conducted on July 28 to July 30 in order to determine the effect of air speed over the bags. The trickle roof module was used to investigate the heat loss rate from water flowing down a tilted surface. Tilts of 10/sup 0/, 25/sup 0/ and 42/sup 0/ were used, and the flow rate varied from 0.5 gpm to 1.5 gpm. The dependence of heat loss rate on inlet temperature was also tested by heating the inlet water.
