ABSTRACT
Electrical lighting accounts for a considerable proportion of energy consumption and consequent carbon emissions in countries where electricity is primarily generated using fossil fuels. In this context it is essential to make electrical lighting as efficient as possible in order to reduce energy consumption and carbon emissions. The efficiency of electrical lighting can be increased in two ways: by selecting energy-efficient lamps and by increasing the control efficiency through zoning, occupancy control, daylight-sensitive switching, daylight-sensitive dimming, low ambient lighting and task lighting, and high frequency control gear. Appropriate zoning that takes daylight into account connects all lamps that are at daylight distance from windows to one electrical circuit controlled by a single switch. Daylight-sensitive switching assumes that each lamp is controlled independently. In order to instruct the simulation software to conduct daylight-sensitive switching and dimming, people need to implement these control profiles in section that sets internal gains from lighting for individual spaces.
