Re: [EnergyPlus_Support] Summary reports problem - Demand end-use is 0 W, while energy end-use is not 0kWh

Remember that the Demand End Use Components Summary is the 
power use for each end use component at the specific "time 
of peak" shown at the top of the table when the peak demand 
for the entire building for that energy was set. Exterior 
lighting for example would probably not be part of the peak 
electrical demand because it occurs at night and the peak is 
probably set during the day. The same goes for heating and 
cooling depending on the timing of the peak demand for the 
building.
