Daylighting Video (Text Version) Below is a text version of the
Hospital Energy Alliance video showing the importance of
daylighting to hospital energy efficiency, staff performance and
retention, and patient healing. Daylighting brings natural light
into hospitals to reduce the use of electric lighting.
Daylighting has also been shown to aid in patient healing, to
improve the work environment of staff, and to enhance the well-
being of patient families. Daylighting is using the sun to
offset electric lighting. And so there is a huge potential for
energy savings there because you're using the glass to help
provide some function in the building other than just views.
You're actually using it for energy savings. We can almost
eliminate cooling in probably 50 percent of the hospital just by
reducing the loads: reducing the solar gains, controlling the
light, and being very careful with equipme
