It appears that the sun room is now going to be included within the building envelope.
Therefore, it should be considered an addition and must comply with the Washington State
Energy Code:
a. Please specify the path of compliance to satisfy the requirements in section 406,
specifically Table 406.2. Adding up to 750 ft2 requires that 0.5 energy credit be
earned.
b. The minimum allowable insulation value, for new framing are as follows:
Roof R-49 (R-38 at vaulted rafters)"
Walls R-21
Note that those values could change depending, on the path of compliances to l a.
Sheet 5 shows 2x10 rafters supporting the roof, but sheet 7 shows 4x4 framing. Please
clarify.
Please specify the connections between the 2x10 "ridge board" (ledger) and the existing
house.
Specify the fasteners and spacing to be used for the sheeting on the walls and roof.
Specify the anchor bolts and spacing to be used to connect the mud sill to the foundation.
