so I can not load the time series on the schedule and make change that ?? first af all thanks for your answer! I had read here on the forum that it was possible to load the schedule as actuators and then write a program with EMS to make the value change. I have thought of doing it this way to avoid loading 8760 values in costruction also because I want to change the u factor in WindowMaterial: SimpleGlazingSystem then as the sole costruction I have this.

EnergyManagementSystem:Actuator, U_TRADIZIONAL_ACTUATOR, !- Name U-Traditional, !- Actuated Component Unique Name Schedule:File, !- Actuated Component Type Schedule Value; !- Actuated Component Control Type

EnergyManagementSystem:ProgramCallingManager, MY U VALUE SCHEDULE , !- Name UserDefinedComponentModel, !- EnergyPlus Model Calling Point U_VALUE_PROG; !- Program Name 1

EnergyManagementSystem:Program, U_VALUE_PROG, !- Name IF (Hour == 1), !- Program Line 1 Set U-Factor = U_VALUE_ACTUATOR, !- Program Line 2 ENDIF; !- A4

EnergyManagementSystem:GlobalVariable, AVERAGE; !- Erl Variable 1 Name

it is wrong to do so? perhaps the part of the program should be written as I've proprosto but adapting it to my attutatori? thanks again for your answer
