[Equest-users] EMS Control System Modeling

[Greg Collins]

Charles - A quick suggestion for the setback is to try setting your
system fans to "cycle on any."  Otherwise, your system might not kick on
to maintain setback temperatures.

I am doing an quick estimate for adding EMS control to an existing HVAC
system (schools) which incorporate the following measures

 

1)    Automatic thermostat setbacks for building occupation

2)    Demand controlled ventilation

3)    Economizers

 

Here are my "challenges"
1)    Simulation with setback temperatures shows no reduction in energy

2)    I am unsure how to handle DCV

3)    Simulation with economizers show very little reduction

 

I would appreciate any pointers, suggestions, etc. on what to do here.

I would especially appreciate any example files to see how you input the
data to get proper results.

 

 

Thanks in advance for any help.
