If by high tech buildings you are referring to a modern office buildings,
then loads from desktop PC's, monitors, printers, copiers, etc. typically
will be about .5 watts per square foot, but may range from .5 to 1.0 watts
per foot. Note the actual power use by such equipment is well below
the nameplate power data.
<p>Refer to published ASHRAE papers, starting in 1994, authored by Chris
Wilkins, who reported on extensive monitoring of such loads in real world
office buildings.
<p>Lighting loads, refer to 90.1-1999 for maximum power densities permissible
for office occupancies. But lighting designers who apply efficient
fixtures for interior lighting design can easily achieve excellent illumination
levels using well below 1.0 watts per foot.
