My I ask what the difference between Zone Windows Total Heat Gain Energy and Surface Window Heat Gain Energy is?
It's explained in the E+ document that:
Zone Windows Total Heat Gain Energy [J]
The sum of the heat flow from all of the exterior windows in a zone when that sum is positive.
whereas
Surface Window Heat Gain Energy [J]
The total heat flow to the zone from the glazing, frame and divider of an exterior window when the total heat flow is positive.
Does this mean that the sum of the Surface Window Heat Gain Energy for all the windows of a given zone equals to the Zone Windows Total Heat Gain Energy of that zone?
However, the total across all the zones and surfaces for both variables are not the same, it seems.
