Natural Lighting and Cubicals

Fowarded on behalf of  Tim Greiner <tgreiner@kgaainc.com>


There have been a number of studies comparing human performance in daylight
areas versus non-daylight areas.  See
-- there is one study that found improved academic performance of public
school kids when in rooms with more daylight.  I have also heard of a US
Postal Service study that showed huge productivity improvements in a mail
sorting facility when daylighting was introduced.  I suppose finding a
study specific to a white collar environment would be most helpful...
perhaps the folks at PG&E would be helpful.

This web site has a daylighting bibliography.
