View access index: The effects of geometric variables of window views on occupants’ satisfaction

One of the important aims window design is to provide quality views that affect occupant health, well-being, and work performance. We assessed effect geometric variables (i.e., view angles, glazing area (Window-to-Wall Ratio, WWR), distance, viewing direction percentage in visual field (PWV)) had on occupants’ satisfaction access. conducted a human subject experiment with 40 participants using simulated images displayed virtual reality headsets. Each participant rated being presented various combinations. The results showed (WWR), were three primary predictors for access satisfaction. Based empirical results, we developed index. This index found satisfactory cannot be achieved WWRs < ∼25%, level did not increase substantially when > ∼65%. proposed first model predicts by considering complex interplay multiple derived from an immersive environment. Given impact area, distance have workplace, it integrate them during early stages building design. For minimum requirements, recommend horizontal angles are greater than 25% 35°.
