Revision history [back]

I can tell that the DOE reference buildings were created with data from 2033 CBECS. I am wondering how the individual space types were assigned. For example, the reference building for secondary school uses an air cooled chiller and packaged single zone units. I do not understand what rationale the modelers had for placing each HVAC type where? Why are certain space types cooled by the chiller, but others by the single zone units? How would I find this information? I am interested because I have to interchange HVAC equipment from these reference buildings, and would like some reference for where to put what types of HVAC in a building on a space type level of detail.
