In order to ensure that daylit buildings will become the preferred option in
this millennium, it is necessary to optimise energy savings by taking into
account the integration of daylighting, control systems and occupant response
and transferring this new research to design professionals and industry.
Currently only a small fraction of daylighting possibilities is being captured
in buildings and many are beset with problems. There are failures of supposedly
well-designed systems to achieve their expected performance due to a lack of
consideration of integration issues such as the incompatibility of daylighting
systems and control systems. There are adverse reactions to discomfort glare
from daylight, poor use of ceiling and wall materials, and poorly designed
daylighting systems that can generate strong luminance contrasts causing glare.
These can result in visual discomfort, the pulling down of blinds and the
reduction of daylight usage.
These problems cannot be solved by the architectural or engineering professions
on their own, as these are fundamentally integration issues. Without an
integrated approach the potential savings from daylighting and control systems
will not be realised.

efficient building with good daylight. It is naturally ventilated, and only the
north facade is “completely” glazed. © Steen Traberg-Borup, The Danish Building
