Study on the Affect of Aspect Building Form and Layout Case Study: Honjo Nishi Danchi, Yahatanishi, Kitakyushu-Fukuoka

Abstract

The urban layout, from the form and placement of the building complex, configures open space and creates a distinct microclimate. This paper, then, tried to compare two building groups which have different building layouts (size, shape and orientation) in the same neighborhood to seek site microclimate. The numerical model of ENVI-met was used with specific temperature, humidity and wind speed; that would simulate the microclimatic change within urban environment. This model was practiced on the hottest day in summer at 7th August in Kitakyushu (33°50’N; 130°50’E), a region characterized by warm and humid temperatures in hot summers and no dry season. A description of microclimate with different orientation would be the emphasis and it was placed during the daylight into the building. The results showed a pattern of mean radiant temperature (MRT) correlated with building layout and its configuration created open space. A comparison of building group revealed that time and period during the day when extreme heat stress occurred provide a better building configuration.
