Abstract
A method of improving the thermal environment by floor plan changes focusing on non-air-conditioned rooms with undressing activities was proposed to reduce the risk of heat shock. In this study, the influence of floor plan changes on the indoor thermal environment from the perspective of summer health in a detached house in temperate climate was verified by numerical simulation. As a result, the floor plan changes models focusing on non-air-conditioned rooms showed a small difference from the original model in terms of room temperature in the living room on the hottest day. However, in the room temperature of the toilet on the hottest day, it was up to 4K lower than the original model. Furthermore, some models showed a reduction in WBGT in non-air-conditioned rooms, suggesting that floor plan changes may improve the risk of heat stroke in non-air-conditioned rooms.
