[EnergyPlus_Support] Re: Question about "Zone List Multiplier"?

["bsiengineer" <arch_engel@xxxxxxxxxxx>]

A colleague of mine had a very similar problem.  He used a zone 
multiplier of 8, and electricity consumption increased by a factor 
much greater than 8.  Using multipliers of 32 to 64 the consumption 
started to decrease.  I can post his .idf if anybody is interested.
