Air temperature in natural classroom is 29oC, and floor, seats, wall surface temperature are 28.1oC influenced by ground contact. When seated, body skin (32OC) would conduct hat through the ground surface as conduction. With evaporative technique in outside landscape, MRT will lower than landscape significantly. In the sample classroom ceiling temperature is 29.4OC effecting from high insulated roof system while outside roof surface temperature is 60.2oC.
