Light Guide in historic residential building

Light Guide Supplies several floors with daylight

Problem:
There was very little natural light on the upper floor and in the center of the house. One reason for this was the traditional Bernese hipped roof with a deep overhang, which severely restricted the amount of natural light entering the building.

Concept and solution by Heliobus®:
Heliobus® developed a custom daylighting concept in which natural sunlight and daylight are captured through a south-facing roof opening. From there, the light is directed through a vertical, mirrored shaft from the attic to the upper floor and on down to the ground floor.

Strategically placed light sources provide natural daylight and direct sunlight to a total of four different rooms. This ensures that light is directed precisely where it is needed in the building—including areas that are difficult to reach with traditional window solutions.

Customizable light control:
Motorized light control allows users to flexibly adjust the distribution of natural light. For example, maximum natural light can be directed into a specific room, while less-used rooms remain dimmed accordingly.

The project demonstrates how well-designed Daylight Engineering can provide natural light to Daylight Engineering floors of a building and sustainably improve indoor environmental quality.
