Abstract
Effective and reasonable daylight can create a comfortable and healthy lighting environment, and significantly affect the quality of indoor light environment in office buildings. Reasonable architectural form design can improve indoor light environment quality and visual comfort degree, and has great significance. Combining with light climate characteristics in severe cold region, the study based on parametric model, aims to analyze the influence degree of the window-wall ratio, glass transmittance and window shape on lighting comfort of westward office buildings. Taking a westward office building in Harbin as an example, Rhino & Grasshopper is used to establish the parametric simulation model. Using different conditions of Window-Wall Ratio (WWR), Window Height (WH) and Height-Width Ratio (H/W) as variables to calculate the value of Daylight Factors (DF) and Daylight Discomfort Probability (DGP) through the control variable method. Adopting the regression analysis, the correlation between above three exterior window variables and the lighting comfort degree is studied, and the optimal design strategies for lighting environment of western office buildings in severe cold region are summarized. The results show that when the WWR is 0.2-0.3, the daylight comfortable performance is the best, the WH is about 0.9 and W/H is between 0.4-0.8, the office building has better daylight comfortable quality.
