徽州天井式建筑采光模拟与分析

Daylight Simulation and Analysis of Traditional Building with Patio in Huizhou

以徽州天井式公共建筑南湖书院为研究对象,分析天井这一空间形态对室内采光效果的促进作用。利用采光模拟软件ECOTECT,模拟全阴天工况下天井对室内采光效果的影响;利用对该建筑自然采光效果现场实测验证采光模拟结果的正确性。通过对天井开口方式进行改进设计,分析得,将天井设于院落两侧采光效果与原模型相当,并且可有效避免厅堂内阅读区域阳光的直射而引起的炫目。模拟和实测结果均表明,天井作用下南湖书院中志道堂和文昌阁采光效果较好,达到人体对光照舒适度要求。

South lake academy, the traditional building with patio in Huizhou was taken as the subject to analyze the daylight effect of patio. This promotion in the standard overcast sky model was calculated with ECOTECT,and also verified the effectiveness of simulation results by field measurement.After improving the patio opening pattern, the lighting effect of the patio locating on the both sides in courtyard is the same as the original model,and it can reduce the dazzling caused by the direct sunlight in the reading area effectively. By comparing the simulation results and field measurement results, it is revealed that daylighting for Zhidao school and Wenchang pavilion in south lake academy is quality and meets the qualification of body comfort for illuminance.
