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.
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 ...

These glassed areas are also known collectively as the car's daylight opening (DLO). To distinguish the greenhouse from DLO, the greenhouse is a superset which also includes the metal structures above the beltline: in general, these include the roof and all pillars separating the glass and upholding the roof.

Daylighting a tunnel is to remove its "roof" of overlying rock and soil, exposing the railway or roadway to daylight and converting it to a railway or roadway cut.Tunnels are often daylighted to improve vertical or horizontal clearances—for example, to accommodate double-stack container trains or electrifying rail lines, where increasing the size of the tunnel bore is impractical.
