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.
