Dear Group,
I am currently trying to simulate a room with no internal loads (people, lights and electric devices), no convection (no wind, no ventilation and infiltration). I am trying to show only the conduction effects through the walls, so I also tried to reduce the effects of the radiation.
To make sure that my simulation would work, I created an EPW file with a constant Dry Bulb Temperature at 5°C. Normally, the operative temperature in the room after a few weeks/months should also be 5°C. However, after running the simulation, I got 0.5°C in that room. All the 6 surfaces are made of 20cm thick concrete, and they are towards the outside. There is no wind and no sun on these surfaces.
I observe that the roof outside surface is -5°C and that the floor outside surface is +5°C, but I am not sure how to explain these differences. Does anyone have an idea?
Thanks for you attention,
Sarah
