Encapsulated vs. Conditioned Attic: HVAC Design Tricks to Get More Accuracy from Manual J Wrightsoft
WHY and HOW I model encapsulated attics as actual conditioned space, which gets a Btu and CFM assigned to them. You can see the load difference starts to really stack up with the amount of variables that go into it. Using Wrightsoft load calculation and SketchUp 3D modeling softwares. Thanks to Alex Meany (https://MeanHVAC.com) for teaching me how to work this magic on Wrightsoft.
