A Design Methodology for Perimeter Block Housing Considering Day-lit Environments and Energy Performance

摘要

Perimeter block housing was introduced from the 2000s as an alternative means of urban construction that has been polarized between the large-scale development of high-density high-rise buildings and the development of small plots of land. The results of this paper allow the possibility of forming building types that satisfy the standard of two consecutive daylight hours for all households by using the properties and principles of shadows in perimeter block housing. It also provides the possibility of the combination of building forms without daylight interference from the south mass by manipulating the distances between adjacent buildings at different azimuth angles. Furthermore, comparing the energy load of residential buildings as suggested from the results of the study, it was possible to confirm whether residential buildings optimized for the day-lit environment have an effect in terms of energy usage performance, and further suggested planning directions through the analysis of daylight, sunray, and energy load. The study suggests a rational methodology for the layout of residential buildings that is optimized for the day-lit environment and also considers the issue of energy performance.
