Solatube Tubular Daylighting Devices, or TDDs for short, are high-performance, green building components that bring daylight into interior spaces where traditional skylights and windows cannot reach.

TDDs have become the ideal solution for lighting interiors in a cost-effective, energy-efficient and eco-friendly way because they significantly reduce the need for electricity while keeping people connected to the outdoor environment. The incorporation of optical technologies significantly improves the way daylight is captured and delivered to interiors. Solatube Daylighting Systems are modular and easy to connect to ceiling systems. And unlike traditional skylights, they are designed to control the problematic aspects of sunlight. Glare and inconsistent light patterns are reduced. . They also screen infrared rays that can overheat interiors as well as ultraviolet rays that can fade furniture and fabrics.

Implementation Stories

Solatube Tubular Daylighting by Solatube
Implemented by ESAT in Montfermeil (France) in 2017

L’ESAT de Montfermeil, a medical and social establishment whose objective is the social and professional integration of disabled adults, used the Solution to introduce daylight into an extension of the building in 2017. Having a nice level of natural light in their work area was crucial for the occupants, as it improves their comfort and reduces their stress. 21 daylighting systems were installed: 18 in the work rooms with 6 Solatube per room and 3 in the corridor.
