Light Guide in historic residential building

Light Guide Supplies several floors with daylight

Problem Statement:
Little daylight on the upper floor and in the center of the house due to a traditional Bernese cripple hip roof with a low-pitched canopy.

Idea and solution by Heliobus:
Daylight is directed from a roof opening towards the south through a vertical, mirrored shaft from the attic to the upper floor and first floor. Openings with controllable light outlets supply four different rooms with daylight & sunlight.

Light control is individually controllable
A motorized light control allows the user to control the daylight as desired, e.g. maximum daylight enters one room, dimming the unused rooms slightly.
