| Abstract |
The purpose of this study is to clarify the effects of compositional elements of building floor plan on qualitative and quantitative spatial efficiency for high-rise residential buildings. Exclusive area ratio, public corridor area ratio, interior corridor ratio, and residential area ratio was considered for quantitative spatial efficiency, while approach-escape distance, interior-perimeter zone area ratio, non-residential area ratio of perimeter zone, and effective ratio of external surface length was considered for qualitative one. The results of study are as follows; For the quantitative efficiency, public corridor area ratio is more prominent factor that effects on the efficiency than others, and different efficiency in exclusive area ratio and residential area ratio may result from the planning of core space. For the qualitative efficiency, interior-perimeter zone area ratio is the most dominant factor that makes the difference of spatial efficiency and other factors also demonstrate significant differences depending on the floor plans. In terms of the corelation among the factors, exclusive area ratio and interior corridor ratio have a negative relationship in quantitative efficiency, while interior-perimeter zone area ratio and non-residential area ratio have a positive relationship. As an corelation between the quantitative and qualitative efficiency, a negative relationship can found between the interior-perimeter zone area ratio and public corridor area ratio. |
