Daylight harvesting systems use daylight to offset the amount of electric lighting needed to properly light a space, in order to reduce energy consumption. This is accomplished using lighting control systems that are able to dim or switch electric lighting in response to changing daylight availability.
Artificial lighting energy use can be reduced by simply installing fewer electric lights where daylight is present or by automatically dimming or switching off electric lights in response to the presence of daylight – a process known as daylight harvesting. The amount of daylight received in an internal space can be analyzed by measuring ...
Electric lighting energy use can be adjusted by automatically dimming and/or switching electric lights in response to the level of available daylight. Reducing the amount of electric lighting used when daylight is available is known as daylight harvesting.
Why do we spring forward and fall back with our clocks each year? Daylight Saving Time was a way to save fuel and make the most of sunlight during World War I, but it stuck.
Daylight saving time for 2024 began at 2 a.m. EST Sunday, March 10, for "spring forward" and will end at 2 a.m. EST Sunday, Nov. 3, for "fall back."
Daylight saving time (DST), also referred to as daylight saving(s), daylight savings time, daylight time (United States and Canada), or summer time (United Kingdom, European Union, and others), is the practice of advancing clocks to make better use of the longer daylight available during summer so that darkness falls at a later clock time.
The U.S. tried permanent daylight saving time in the 1970s, but Congress reversed it after one year due to complaints about no sunlight in some parts of the country until 9 a.m.
"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 ...
