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.
