With Operating schedule to 12/5 and Roof of R38
Building Envelope Choices:
Wall construction is set to be 14 inches ICF. South and Northern Wall ratio didn’t change it too much, change West and East wall with window to wall ratio to 15%. Window shade and window glass type will not change that much.
Power and Lighting:
It is 5.8 kBtu/ft^2/yr than the building envelopment.
Set payback limit to 20 yrs and PV coverage to 90%, and pane efficiency to 20.4:
It lower the building in 41.78 kBtu/ft^2/yr
My recommendation is to both adding the PV panel and increasing the lighting:
With PV panel of 60% since they are expensive and reduced plug load and lighting efficiency a little
