Actuating the Water Inlet Node/Water Outlet Node Setpoint Temperature of DOE Large Office has no effect on the Overall Energy Consumption

I'm using Gym-EPlus to vary the Setpoint Temperature at runtime using the following Actuator.

ExternalInterface:Actuator,
ChilledWaterTemperature,  !- Name
COOLSYS1 CHILLER1 WATER INLET NODE,    !- Actuated Component Unique Name
System Node Setpoint,  !- Actuated Component Type
Temperature Setpoint,          !- Actuated Component Control Type
;                       ! initial value

I wanted to see what the overall energy consumption would be if I set the value to 6, 8 and 10 at all times during the simulation. But it seems to have no effect on the HVAC system and the energy consumption parameters are the same.

I'm trying to replicate few papers that save energy by varying the Chilled Water Temperature. Is this the equivalent actuator of that? Why does it not change?

I'm using the Large Office IDF File from https://www.energycodes.gov/prototype-building-models
