Yes the Gable walls are insulated. I would like to give you some more information on the subject. The house is all electric and his bills is the winter are around $400 and in the summer around $600. For a house this size they don’t seem to be that far off. Especially not representative of a house with no insulation. The only exchange of air between the main body and the attic space is the large number of can lights in the house. When I model the house with no insulation and then make an improvement it shows a savings of over $2000 a year. I feel like this would be a large misrepresentation to present this as it stands which is why I was hoping that you guys could help with the best way to model this home. Thanks
