I am running the prototype building energy models for medium size office buildings in energyplus. In the parametric study, I am testing the change in energy consumption with respect to increase in cooling setpoint (72 to 77F) while keeping the heating setpoint constant 68F.
For an increase in cooling setpoint, I see the drop in cooling energy which is expected, however, most of the HVAC savings are coming from a drop in terminal electric heating energy. For example, for San Francisco, the increase in cooling setpoint from 72F to 77F is resulting in 68% drop in reheat coil energy. Am I missing something?
