[Equest-users] Gated Community & Roof reflectivity

[Yusuf Turab]

Hello Group

   - Why do I get unmet hours even when I select the auto size option in
   the HVAC system? What is the point of auto sizing?
   - Is there a way to simulate all 4 orientations and get an average
   result for the base case?

Thanks
