Implemented a sample building in EnergyPlus to analyze the impact of occupancy on zone temperature. The metabolic rate was set as 500 W/person. When certain number of people enters a particular zone, the zone temperature is not rising and when they leave the zone, temperature is not lowering. The plot is given below:

I am looking for a model like the below one where there are fluctuations in zone temperature upon occupancy. The drawing may not be the exact representatives but to just show the behavior.

Could anyone help me to achieve this behavior in EnergyPlus

Do you have HVAC equipment in the building? If you do and correctly set-up, then the temperature wouldn't change.

HVAC is a water cooled VAV system. The plant side is chiller, cooling tower, and boiler. The chilled water from chiller or the heated water from boiler is pumped to AHU by pumps. In the AHU, there are supply fans. In cooing tower, there are also fans. Could any chiller capacity adjustment or other controller setting bring the expected result?
