Abstract
It is expected that “green curtain” have the cooling effect of indoor thermal environment by shutting out the sunshine in summer season. However the cooling effect of green curtain which had been gained from the research about the reduction of electricity use of households who installed green curtain was more than the cooling effect from the result of experiment which had measured the indoor thermal environment. Therefore, on the assumption that green curtain influence the psychological reaction of indoor feeling temperature, the experiment, participants stated feeling temperature in the rooms which setting up green curtain or not, was conducted at the apartment building owned by Urban Renaissance Agency. At the result, when sensible temperature: SET∗ of rooms are equal, the stated temperature of participants in room which setting up green curtain was low than the stated temperature in the room of no green curtain. We could recognize that green curtain influenced the psychological reaction of participants.
