Continuous daylight autonomy, is similar to daylight autonomy but partial credit is attributed to time steps when the daylight illuminance lies below the minimum illuminance level. [43] For example, if the target illuminance is 400 lux and the calculated value is 200 lux, daylight autonomy would give zero credit, while continuous daylight ...
Daylighting is the opening up and restoration of a previously buried watercourse, one which had at some point been diverted below ground. [ 1 ] [ 2 ] Typically, the rationale behind returning the riparian environment of a stream, wash, or river to a more natural above-ground state is to reduce runoff, create habitat for species in need of it ...
Daylight is the combination of all direct and indirect sunlight during the daytime. This includes direct sunlight , diffuse sky radiation , and (often) both of these reflected by Earth and terrestrial objects, like landforms and buildings.
Calculating daylight factors requires complex repetition of calculations and thus is generally undertaken using a complex software product such as Radiance. This is a suite of tools for performing lighting simulation , which includes a renderer as well as many other tools for measuring simulated light levels.
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.

A retractable skylight rolls (on a set of tracks) off the frame, so that the interior of the facility is entirely open to the outdoors, i.e., not impeded by a hinged skylight. The terms retractable skylight and retractable roof are often used interchangeably, though skylight implies a degree of transparency. Tubular daylight device
Earth daylight on the June solstice Earth daylight on the December solstice Daytime length or daytime duration is the time elapsed between beginning and end of the daytime period. Given that Earth's own axis of rotation is tilted 23.44° to the line perpendicular to its orbital plane , called the ecliptic , the length of daytime varies with the ...
