Re: [EnergyPlus_Support] Heating:Electricity

["Michael J. Witte" <mjwitte@xxxxxxxx>]

I am assuming this is the same input file that we were looking at last month 
(2e3102.imf).  This mode is a VAV system serving 16 zones with hot water reheat 
coils served by an electric boiler.  The VAV "Zone Minimum Air Flow Fraction" 
fields are all set to either 0.3 or 0.5, and the reheat coils and boiler are 
scheduled to be on at all times the fan system operates.  So, whenever a zone 
sees a cooling load below 30% (or 50%) of the peak design cooling load, the 
reheat coil will come on to prevent overcooling.
