A number of studies have been carred out on the passive cooling of the outer surface of building for the purpose of conserving energy without resorting to fossil fuels, while simultaneously improving the indoor thermal confort. In addition, the heat island phenomenon has been regarded as a problem. Thus, it is necessary to strive to reduce the thermal load of buildings on the urban
environment. In this study, an outdoor experiment was conducted using test specimens with a focus on passive cooling on rooftop surfaces in summertime to clarify the cooling effect of various types of passive rooftop cooling. The influence of rooftop cooling on the indoor heat load, and the heat load of the atmospheric side were also clarified. A total of 10 types of data were collected; case 1 is an AR surface, Case 2~5 are watered AR surfaces, Cases 6 and 7 are ceramic tiles, with and without water coating or white paint respectively, and finally, Cases 8 and 9 are perforated bricks, with and without a coat of white paint respectively. (1) Results of data
analysis for Cases 6~10 show that because these types can reduce the load on the air during the day, they are effective. For Cases 7 and 9 and during the day, the heat island effect is suppressed. For Case 6~9, the tropical night phenomenon can be prevented. (2) In order to reduce the cooling load in summer, the roof slab insulaion to reduce heat load in the atmosphere is essential in order to employ an effective passive, the roof slab insulation to reduce heat load in the atmosphere is essential in order to employ an effective passive cooling method.
