This document provides a design process for daylight openings in order to ensure the principle of sustainability in the indoor visual environment. The design process for daylight openings includes the consideration of: — sunshine duration in the building interiors; — daylight opening ratio to the wall area of a habitable room; — daylight opening ratio to the floor area of a habitable room; — appropriate levels of indoor daylight based on human visual needs and the extent of sunlight; — daylight control systems in the building; — thermal comfort, thermal gains and energy efficiency. This document is applicable to building environment design for new buildings and the retrofit of existing buildings.
