[Equest-users] Hot water loop demand and boiler sizing

[Josh Doherty]

Energy Modelers,
I am getting the following warning message when I type in the actual boiler capacity:

"Hot Water Loop:  the heating capacity is smaller than the secondary demand.  Primary = -2000000 and Secondary = -2992234."

If I let eQuest size the boilers, everything is fine...so I know it has to do with me putting in the actual boiler capacity for the proposed design.  However, the issue here is there is no way the max heating demand is almost -3.0 MBh as it states in the warning message.  I can not figure out where eQuest is getting this number; especially since the SS-D report (which should tell me the absolute max load demand on the building HVAC system - including outside air) says the maximum heating load is -1035.026 MBh.  Can anyone please help me determine why I am getting this error, where the -2992234 number is coming from, and if the SS-D report really is the actual maximum HVAC load demand?  Thanks everyone for their help. Your time is very much appreciated.

Josh Doherty
