Heat Transfer Through Walls
Posted by Richard Raustad, Last modified by Michael J. Witte on 28 November 2017 07:16 PM
What report variables are available for heat transfer through walls? The simulation shows the zone temperature is lower than outside temperature, but the heat transfer through walls appear negative.

There are no report variables for simple heat transfer through a wall.

There are many reasons this can occur. The usual reason is that solar and thermal radiation energy can heat up the inside surface above the zone air temperature and cause heat flows in the opposite direction of what the air temperature differences would indicate. The storage and release of heat inside the walls due to heat capacity can also lead to this situation.
