Electrical power consumption for lighting is a major factor in the energy use of buildings. Office buildings typically use 17% of their energy consumption for electric lighting. For schools, the figure is an even higher 30%. Savings in lighting costs are among the most easily achievable for existing buildings, by dimming and switching lights off (demand reduction) and by installing more efficient light bulbs (system efficiency).
Daylight harvesting is the way that new green buildings are designed to collect and utilize natural daylight in the interior of buildings, when available, to reduce the need for energy-consuming artificial lighting. All buildings have windows, of course, that provide some daylight nearby, but green buildings are designed to maximize that light and distribute it effectively deeper into the building. Older buildings have electric light systems that are turned on whenever the building is occupied – day or night; but buildings that utilize daylight harvesting have automatic lighting control systems that measure the amount of natural light in each space and adjust the electric lights accordingly, to provide just that which is needed to provide the correct level of illumination. The need for electric lighting will change depending on the time of day – day or night, the position of the sun – and with the weather.
