<b>Subject:</b> [Bldg-sim] Survey regarding types of HVAC systems used?</span><o:p></o:p></p>
<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outdated), that would be a big help.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>
<br>
