This tool helps to help compare alternative designs in terms of Daylight Factor, Autonomy, Irradiance, etc.
The analysis shows how different designs lead to different results in Daylighting and how efficient a scenario may be. It is particularly useful to understand the impact of protections.
Ratio of the solar irradiance (W/m²) to the theoretical irradiance of an identical but virtual and isolated surface without surrounding surfaces. The Watt Reduction Factor can be interpreted as the normalization of a standard Watt calculation by the maximum reachable with the local climate.
Sky Factor and Rights of Light
Ratio of illuminance received directly through unglazed openings, to illuminance on a horizontal plane due to an unobstructed hemisphere, for a standard CIE overcast sky luminance distribution.
Natural light is an essential part of architecture and urban planning.
Key element of architectural and urban plasticity, it plays an important part in comfort, pleasantness and well-being.
It plays an essential role in the control of energy consumption. In many buildings, the quantity of energy spent for artificial lighting is greater the one spent on heating.
DL-Light helps architect, urban planners and technical offices in their quest for performance, comfort and pleasantness of luminous ambiances and to improve energy consumption control.
