    I'm not the original owner but I have construction photos and it's just attic trusses with some fiberglass mats. I agree the codes should be improved for these type of rooms.

    [QUOTE=dan sw fl;25847365]IF you really wish to KNOW about a more accurate and Appropriate thermal model
    you can provide:

    1. monthly utility bills/ ENERGY USAGE
    2. Infiltration amount (A.C.H. Natural ) from a Your BLOWER DOOR TEST
    _______ or CFM50 & house volume

    3. Windows: S.H.G.C. _ 0._ _ / U-factor 0. _ _
    _____ I believe that LoadCalc overestimates Heat Gain on Superior Grade glass (S.H.G.C. < 0.29)

    Alternative
    *** Use a separate, small Mini-Split Heat Pump for FROG


    Thanks for the offer. I'm good with a ball park figure for now.
