 Abstract
Environmental issues of building located in complex and dense cities are easily exposed to be affected by surrounding buildings. However, the building energy simulation generally has not been reflecting the solar shading of adjacent buildings. This paper investigates the impact of adjacent buildings on the loads. Based on EnergyPlus simulations of a building, the relationship between shaded area ratio and cooling/heating load was analyzed. In addition, this study was conducted with variables of direction, distance and exterior materials. As a result, the more the distance is further away, nearer to the south-facing and the higher the reflectivity of the material, the cooling load was reduced. However, heating load showed the opposite trend. Annual loads was reduced from 11% to 17% due to the adjacent buildings. The research findings would contribute useful base information for building design and study materials, such as related field of cooling/heating load calculation in density urban cities.
