Exploration on Effects of Tinted Glazing on Outdoor Views and Visual Experience Inside Hotel

Modern lifestyles result in people spending 90% of their time indoors, where windows serve as a unique component providing an outdoor view and enabling visual experiences. Chromogenic windows, which adjust both thermal and visual conditions, represent a promising fenestration system for achieving energy savings. However, the tinting properties and their effects on human responses to filtered window views have not been thoroughly explored. This study conducted an experimental test using a customised questionnaire to investigate eight distinct window conditions in a hotel building. Forty-five participants took part in this evaluation by observing photographs. The conclusions drawn are as follows: (1) All tinted windows were found to be less acceptable than clear windows; however, the bronze window was relatively preferred. (2) In terms of visual capacity, the red window had the most negative effect, followed by the blue window. (3) Considering the window views, the tinted windows significantly disturbed the view outside. These results have the potential to guide the development of chromogenic windows in practical applications in the future, particularly from the perspective of colour selection.
