[Bldg-sim] Survey regarding types of HVAC systems used?

[Brahme, Rohini UTRC]

If you look at the the actual survey data files on the CBECS site, it
will list the HVAC type, chiller type etc. and also gives what
percentage of the stock a particular survey data point represents.

Paul, 

  

Poke around CBECS, that info might be in there. I know they have heating
and cooling energy source numbers, not sure if delivery devices are in
there somewhere or not. Might need to do some of your own data analysis
to pull out office spaces.

Hi all,

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.  

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if it is outdated), that would be a big help.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.

Thanks!
