Good morning HVAC Engineers
Thank you for being here for us, beginners
I have a building, it has a drop-down ceiling, and in that area the HVAC supply ducts are disconnected, so the air doesn't go to the room, it stays in the ceiling.
how should i calculate the energy loss in this case, how to calculate the energy for the HVAC unit
i don;t use any software just excel
Thank you !
