Hello,

Hopefully I'm posting in the correct forum subject headings.  I am new to the energy modeling community and had a few questions in regards to District Cooling.  We have a 2 pipe FCU with electric heat and district cooling.  I am unsure how to model the baseline building's heating.  I have read from released documents from USGBC that seem to indicate that the baseline building (with no district heating) is to be modeled with a hot water boiler.  But this assumes that I am working with a 4 pipe system.  I cannot seem to find anything on the 2 pipe system.  Do I just model the baseline with electric heating too?  Or do I model the baseline with a hot water boiler even if the proposed is electric?  Thanks to all in advance for your help.
