Exploring the potential of colored glass in the south façade for optimizing visual comfort

There are several alternatives in the early stages of the design process as passive strategies, including orientation, window to wall ratio, shading device, material and colour that affect occupants’ visual comfort. However, applying simple traditional principles such as using colorful glasses for windows would be effective in the optimizing of visual comfort at interior space. The main aim of the current research is investigating the appropriate colors to control direct sunlight for meeting visual comfort criteria based on climatic-luminance metrics. Furthermore, which combination of them would be more effective for optimizing visual comfort in terms of daylight glare probability? This research reintroduces the main application of colorful glass as a light controller in the window that considerably affects climatic-luminance based metrics containing daylight autonomy (DA), useful daylight illuminance (UDI), Overlit UDI and daylight glare probability (DGP). Combination of quantitative and qualitative research methods have been applied in order to generate hypotheses and then analyze them. Parametric simulation analysis proves that colored glass has the capability to optimize occupant’s visual comfort during office time. Moreover, appropriate combination of colored glasses could be varied depending on function, climate and occupant behaviour.
