The "when" of the unmet heating hours would help. Startup? Cold months only?  You have a reheat system (with your VAV). Try making the deadband larger.

Hello All,

We are trying to model an office campus of around 12 buildings. The chiller plant has around 10 chillers and boiler plant has around 4 nos. of steam boilers. 
On the air side, the systems are a combination of VAV systems and FCUs ( modeled as SZRH in eQuest)        
After adding all the possible inputs, we are not able to meet the unmet hours, mostly in heating. Any hints???



Regards,
