Re: [EnergyPlus_Support] BuildingSurface:Detailed azimuth/tilt





Interesting. If I'm understanding you correctly, that means that a "mismatch" is likely to actually be more accurate, since the sunlight calculation will be more accurate but the heat transfer calculation won't suffer.

For interzone surfaces, these may not matter so much.

Tilts for floors and roofs will matter -- (exterior surfaces because otherwise sun won't hit them, etc).  Not sure about interior ones in that regard (having sun light hit them)

As a follow-up question to my previous question about surface area, I
have one about tilt and azimuth. I know that EnergyPlus emits a warning
if paired surface tilts and azimuths don't "match", but does this case
actually affect the simulation result at all? And what's the epsilon for
"matching?"

Thanks,
Cody
