This project demonstrates how sunlight can be trapped as part of an integrated concept to improve natural lighting and the indoor climate in multi-storey housing.

The unique feature of this project is a light shaft which reflects sunlight from the roof down through the middle of the building. This is achieved with the aid of what is known as a heliostat, which is fitted to the roof.

The heliostat is computer-controlled and tracks the sun’s light, which is projected onto mirrors in the shaft and from these into the flats.

Both the yard-side and street-side facades are insulated and fitted with low-energy windows. This system reduces energy consumption to the level otherwise required in new building projects.
