| Abstract |
The objective of this study is to estimate environmental performance damages of the nearby houses by constructing high-rise buildings. The overshadowing is representative damage by constructing high-rise buildings but the obstruction of skylight, view and ventilation are also the important factors in residential environment. There is a need to propose a new evaluation method that focuses on the openness problems as well as solar access. In this paper, solar access means access to sunlight and solar heat whereas openness means access to skylight, view, ventilation and privacy. The indicators to calculate solar access are the duration of sunshine on the winter solstice and the solar radiation on a vertical surface during the winter. The indicator to calculate openness is Vertical Sky Component which measures unobstructed sky component. These indicators are available to analyze the actual condition. In case study, the one house seemed to be more damaged by high-rise buildings than the other house when used only duration of sunshine, but the estimation used three indicators showed that is not true. |
