color=#0000ff>I think that the the underground wall area should be included for
each floor that has windows. These windows in partially below ground
stories are providing light and views that are no less important than similar
functions provided on upper floors. However, if I have a skyscraper with 4
stories of underground garage of basement areas, I don't think these fully
underground wall areas should be included. Rene, in evaluating the energy
and cost impacts of windows in buildings, it is important to look at
the potential for daylighting or the value of view, otherwise an engineering
analysis might conclude that we don't need any windows at
all.</FONT></SPAN></DIV>

request (CM proposal) to the ASHRAE 90.1 Envelope committee to change the
definition to only include the above grade walls but they declined it so it is
still the above and below grade walls. The reason I sent the request is that
architects tend to add more glazing to the above grade walls because they can
include the below grade walls in the definition. I showed some modeling results
of the difference between a two story building with one above and below grade
wall in a few difference cities in the <st1:country-region w:st="on"><st1:place
