Abstract
Daylight utilization in cites is receiving increasing attention from urban planners and developers, architects, and engineers, especially in China. This article aims to study the daylight availability in highly dense residential areas across China with respect to current planning regulations. Using a method of climate-based analysis, frequencies of vertical daylight illuminance at building south façades in three urban layouts have been assessed according to five typical locations, one of which represents one daylight climate zone. Key findings are as follows: 1) Given the daylight availability, these layouts were proved as suitable for only two southern locations, but not appropriate for others. 2) Current regulations, focusing on ground floors in these layouts, would lead to excessive daylight illuminance and solar gain received at the higher façade. It is necessary to achieve a balanced level of daylight availability across various positions of building façade through an effective approach. 3) Under a situation of the highest building density allowed by current regulations, urban layouts (building forms) might not be able to take substantial effect on the overall daylight availability in buildings.
