How would I find typical HVAC types in buildings?

I am looking to switch out several HVAC system types from DOE commercial reference buildings with 'typical' HVAC systems specific to that buidling type. For example, The reference building for a Warehouse utilizes packaged AC as default (coded into the original IDFs), but I would like to separately model a Warehouse using a heat pump system. How would I find out what a typical heat pump system in a Warehouse is comprised of? Is there a good reference for various building type - HVAC type combinations? I realize this probably varies with climate zone.

The Commercial Buildings Energy Consumption Survey is probably your best bet. Take a look at the spreadsheets under "End-use equipment". There you will find a breakdown of how often each equipment type is used in different types of buildings. For example:

This is helpful, but more general than what I was looking for. Ideally, and I'm not sure there is something comprehensive like this, there would be a similar chart for only Heat Pumps or Chilled Water Systems to breakdown how often specific types of each (e.g. air-source heat pump, water-source heat pump, etc.) would be used per building type. Something on the next level of specificity.

The Commercial Building Energy Consumption Survey that Neal suggested actually includes questions that provide a lot more detail. To get the raw data see:

http://www.eia.gov/consumption/commercial/data/2012/index.cfm?view=microdata

Unfortunately, it is a lot of work to process the data yourself.

Another source of related information is the DOE Buildings Energy Data Book:

http://buildingsdatabook.eren.doe.gov/default.aspx

It does not have exactly what you are looking for but related information that might be useful.

If you are willing to not use a national survey, the Commercial Building Stock Assessment performed by the NEEA covering Idaho, Oregon, Montana, and Washington State shows some details:
