"The most sustainable source of lighting is daylight, other forms are solar lamps harvesting daylight and lighting controlled by occupation sensors. Furthermore technologies such as light-emitting diodes can be used to drastically reduce the energy requirement for energy. Part L of the UK lighting regulations contains criteria that effects efficient lighting design.[4]
Both day lighting and electric lighting are used in architectural lighting design, and not just as something installed to enable people to see their task.
In cloudy
People’s needs and preferences to sunlight dependent on the type of building – incoming sunlight can give warmth and brightness but can also cause glare and thermal discomfort. The designer must to analyses the clients’ requirements in advance to determine which parts of a building would benefit from direct sunlight. Once the day lighting has been assessed, electric lighting needs to be designed to complement the daylight; where necessary electric light will take over when the daylight fades.[7] Zones can be considered relative to the daylight distribution – without this there will be a tendency for the lights to be in all the time. Electric lighting can also be integrated within the architecture. Daylight and the aesthetics can be considered as well as the installation into the buildings fabric and lighting effect.
