Dear users Of EnergyPlus,

I'm using EnergyPlus daylighting model without thermal analysis,plant 
and system. So I have divided the building in simple geometric and 
not thermal zones.  I make a simple daylighting analysis only for 
some zones to estimate the consumptions electrical workers for the 
inner lighting system and to propose solutions in order to reduce the 
consumptions
 
My problem is:
I have a daylit zone with a group of 12 equal rooms but the windows 
in the zone are shadowed by exeterior obstructions like trees and 
other parts of building. In this Way I can't use zone multipliers.The 
solution is:

1. to describe each room as a separate geometric zone (as written in 
input output reference but only for thermal and not geometric zone 
such as my project)

or 

2. to divide these 12 rooms in four similar geometric zones  about 
shadows from external objects  (each zone with 3 rooms).

About the second option:  Is design level (Watt) installed in the 
centre of the ceiling of each equal room or in the centre of the 
ceiling of zone?In each group of zones Can I define two reference 
points in two different rooms?

Thanks in advance,

Marino Davide.
