Analyzing Daylight Conditions for Outdoor Vegetation in Urban Areas using Sky Factor

S. Kwon, S. Han, S. Park, K. Song

Abstract: Daylight is one of the most critical conditions for vegetation growth. However, densely developed urban areas may provide not enough daylight for photosynthesis of vegetation due to artificially built structures. In Korea, the most general housing type is high-rise apartment complexes which were built to maximize the use of high-price urban lands. Many of these apartment complexes have problems related to maintaining healthy vegetation landscape due to not enough daylight. The purpose of this study is to develop techniques to evaluate critical outdoor conditions for vegetation in urban landscapes to help landscape designers select proper vegetation species. This paper presents a technique to combine a photographic method to measure Sky Factors and a computer simulation method to determine sun paths in order to evaluate direct sunlight and diffuse skylight availability at the evaluated spots for vegetation
