Re: [EnergyPlus_Support] Overhanging / Canopy like roof.
Chandan,
Yes I did just that, I ran simulations with an air gap of 0, 6", 1', 1'6", and 2'. As the overhang went higher the annual cooling load decreased. I'm assuming that is due to the loss of shading over the south side of the house.
But shouldn't there be a bigger difference from having no air gap to a 6" air gap.
With no Air gap the roof of the home is being directly heated by the sun but with a 6" air gap the roof of the entire roof of the home is being shaded.
