Comparisons of Height Restriction and Relaxation by Sky Factor Focusing on Digestion Floor Area Ratio and Building Height

Abstract

In this paper, we compare the impacts of height restriction and relaxation by sky factor in terms of digestion floor area ratio and building height. By considering the various site shape and building shape, we evaluate how these regulation affects the digestion floor area ratio and building height. The analyses enable us to grasp the situations which a relaxation by sky factor have large advantages. Main results of this paper are as follows: （i） a relaxation by sky factor is advantageous when the site has large frontage; （ii） by utilizing the setback regulation, it is possible to acquire enough floor are ratio when the site of depth becomes large.
