Re: [EnergyPlus_Support] modelling zones with similar conditions & several types of electr. equipment

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

1.  Specify the outside environment as OtherZoneSurface and set the surface to 
see itself.  For example, the outside face enviornment object for Wall1 is 
Wall1.  See p. 99-100 of the Input Output Reference.  This surface will be 
adiabatic but it will add thermal mass to the zone.

2.  You may use multiple equipment and lights object in a given zone.  However, 
there is a bug in version 1.1.1 for electric Equipment.  You must assign each 
electric equipment object in a given zone to a different end use. For example, 
in Zone 1, assign the first electric equipment object to end use category 1, 
and put the sedon electric equipment object on  end use category 2.  If you do 
not follow this rule, the equipment load will be double counted on the electric 
meters.
