The Study on the Elevation Design of Apartments Incorporating Daylight Performance

Abstract—Understanding the distribution of daylight in a room is essential for predicting the visible comfort and energy saving of each unit. The factors of the elevation design actually decide the building performance because the sun has the fixed pattern. In addition, the indoor environmental conditions are varied according to the location and story of each dwelling even though having the same shape and orientation. For this research, the different types of daylight performance metrics were simulated with Ecotect. According to the simulation of Ecotect, the positional characteristics were shown by the daylight distribution and energy consumption. This paper presents an overview of the apartment facade design by applying four type models with varied WWR. The main results focused on finding the better WWR, and deducing the design to overcome the performance gap.
