Mobirise Site Builder


SketchUp extension
to Study Natural Light
in Architectural and Urban Projects

Our philosophy

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.
