Asda Stores had a number of properties with a
central day lit entrance space and they wanted to investigate how they
could maximise the use of available daylight into the areas that did
not directly benefit from natural light. A model of the daylight opening
was constructed and tests carried out in the Bartlett School of Architecture’s
artificial sky. We examined a number of configurations using baffles
and reflectors to bounce the natural light into the non-daylit spaces
adjacent to the atrium.
The study showed how daylight could be re-directed
to the advantage of a wider area. The reflectors provide an additional
benefit of reducing the daylight directly under the opening thus decreasing
the contrast which assists on visual perception.
