Summary

In recent years, urban areas in Japan have been experiencing a phenomenon called the heat island effect, which causes the temperature in cities to increase to a few degrees warmer than the surrounding suburban areas. It has attracted attention as one of many environmental issues. By utilizing the green roof units as thermal storage tanks and combining it into the building air-conditioning system which has an auxiliary heat source apparatus, a new air-conditioning system with low energy consumption can be designed, and there is the possibility that this technology could provide a solution to both the heat island effect and global warming. This paper relates to an experimental apparatus as a reduction model which we produced to evaluate the effectiveness of this compound system. The reduction model apparatus has a heat storage planter, a tank of hot water, artificial solar heat and an air conditioner. In this paper, we presented operation characteristics of summer mode on this reduction model apparatus, and results show that the green roof building air-conditioning system is one promising candidate as a new building air-conditioning system.
