Re: [EnergyPlus_Support] strange simulation results

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

I see several things which may be contributing to this result:

1.  The floor plan is not rectangular, so all zones have some walls 
facing in each direction.  Because of the triangular sections, the 
northern zones may actually have more southerly exposure than the 
southern zones.

2.  The shading from neighboring buildings is not symmetrical.  There 
is much more shading on the west side of the building.

3.  The weather data indicates that solar intensities are often 
higher in the morning than in the afternoon.  If you run a design 
day, you'll see higher loads in the west zones than in the east.  Is 
it common for afternoons to be more cloudy than mornings in 
Singapore?  This may be the primary driver.
