Abstract

This study aims to find out the shading effect of building structures for an effective plant design. The concept of sunlight duration for building structures is employed, and is built into a 3-D analytic model by AutoLISP and AutoCAD. For a practical concern, it might serve as a reference for plant selection and disposition in a courtyard design. This paper presents a case study of the Life Science Building in NTU. We begin with the simulation of illumination conditions on its north plaza on the spring equinox, summer solstice, autumn equinox, and winter solstice. The illumination conditions are classified into four levels: <1 hour, 1~2.5 hours, 2.5~4 hours, and >4 hours. The illumination level
