Dear Leona,you can do just one thing at a time: Simulate the free floating room temperatures when no heat/cold is supplied OR simulate the cold/heat demand when the room is kept at certain temperature.
What you did is a simulation without a heating/cooling system, so you got the temperature profile.
You need to turn on the aux cooling system in TRNBUILD (assuming you use type 56) and give the building a desired maximum temperature (constant value, input or schedule). When the room temperature reaches the maximum temperature, you cooling system will start to operate, keeping the room below the temperature. Q_sens is the (negative) cooling demand.

Dear all, i want to make a building model for the simulation of cold load.It is just one room with one external wall and 2 unair-conditioned next rooms(one is the lobby the other is the upper room). Questions are 1. I tried to run the simulation, but the cold load is always 0, like the picture in the mail. 2. i think the temp. is also not correct ,but i don't know why. ps. i just want to simulate the temp.and the cold load in 23. July in the zone. Can anyone help me? Thanks and best regards, Leona
