<P>
Hi all,<BR>
<BR>
I have a query regarding the percentage breakdown of types of
HVAC systems used in office buildings. i.e. What percentage of buildings use
VAV, dual duct, radiant systems, NV, etc. <BR>
<BR>
As of yet I have been
unable to find any study regarding this, but I'm hoping that at least one has
been done. Up to date statistics for the US or Europe would be preferred, but if
you know of any information (even if it is outdated), that would be a big help.
Likewise, if you know of studies that are for other types of buildings - labs,
schools, hospitals etc. - please let me know.<BR>
<BR>
Thanks!<BR clear=all>
