| Abstract |
This study estimates the change of sunlight environment on the present relaxation movement of floor arearatio and provides the maximum upper limit of floor area ratio per arrangement pattern of the apartment houses, as aresult obtained from the above estimation. The arrangement patterns had been classified into 4 cases by carrying outcase analysis; Case 1: the parallel arrangement of plates, Case_2, 3: the mixture arrangement of plates and towers,Case_4: the parallel arrangement of towers. And the total 12 analysis patterns including the detail analysis pattern,which the variable factor was the rearrangement of a floor per case, had been defined. In the arrangement of Case_1,we analyzed that the application of more than 250% of floor area ratio, which value is the maximum permitted limitof floor area ratio on the present residential area, was impossible at all analysis patterns. In the arrangement of Case_2and Case_3, we analyzed that the application of 350% of floor area ratio was possible at only two patterns; one isthe pattern of increasing the number of the floors for a tower and the other is the pattern of arranging a plate and atower on the same floor. In the arrangement of Case_4, we analyzed that the application of up to 400% of floor arearatio was possible at all patterns analyzed, with regardless of the change of the number of the floors. |
