Evaluating summer thermal environment of temporary housing unit adapting the layout plan, “Kumamoto Type D”

Abstract

Abstract In Japan, natural disasters have historically caused massive damage, and the importance of emergency temporary housing is increasing. In this paper, the summer thermal environment at the Shirahata temporary housing site in Kousa Town was assessed. The site was constructed following the 2016 Kumamoto Earthquake. The site was improved by applying a design methodology called “Kumamoto Type D,” “D” stands for “Default & Design.” Field measurements and computational fluid dynamics simulations were conducted to investigate the influence of the building arrangement on the outdoor thermal environment for the Kumamoto Type D layout. The results indicated that the impact of wind was reduced using this layout. However, when the surface temperature in the parking lot and other areas increased, hot air could be transmitted to the site, even under reduced wind conditions.
