Energy savings from better wall system / insulation?
I’m looking for charts indicating rough energy savings / heat load changes for various wall system decisions. E.G., going from a standard 2×6 wall (5.5″ = R16.2 @ 16″oc) to a double 2×4 wall (7″ = R20.1 @ 16″oc + less thermal bridging).
I’ve seen charts that show this but have been unable to find them. This is for what is effectively a simple two story woodshop with few windows and none on the north side.
