Design and performance assessments
Highly glazed facades can provide a well day-lit environment. However, more daylight does not necessarily mean better daylight. Even though the view to the outside may improve when large glazing areas are provided, visual comfort might be more difficult to obtain, especially in office environments.
Although sound visual environment cannot be easily defined (it depends on personal preferences and the ability to adapt), discomfort or disability factors that affect visual experience can be assessed. Such factors are glare, uneven light distribution, rapid variation of the lighting conditions within the occupied space and the direction of the light (e.g. low sun angles).
Orientation, location and integration of proper shading systems should be considered when designing highly glazed buildings.
Careful design that incorporates advanced daylight techniques at an early stage, considering visual performance specifications of the given building, can achieve improved views and visually sound indoor environment.
