Apologies if this has been covered many many times...
I am building a garage, with rental apartment above, in Rhode Island.
- Climate zone 5 (or 4-Marine? The humidity-controlled bathroom fan seems to run all summer, windows open)
- 24x36, approximately 800 SF of living area, unheated garage area.
- Glazing: Lots on the South (view) side, minimal on E, N, & W. Mid-range manufacturer.
- Framing 24" OC throughout: 2x6 walls, 2x10 (or 12?) floor, complex truss roof.
- Siding 50% wood shingles, 50% cardboard-cement clapboards (matching the "big house")
- Insulation specs are currently minimum code - R-20 FG in walls, etc.
- Heat: a combination of direct-vent gas fireplace, gas-fired heater TBD
- No installed A/C.
As a rental, it's all about "bang-for-the-buck", every discretionary penny should go toward attracting an upscale tenant. And efficiency in a small rental is NOT sexy. But here I am, lurking in this forum, so apparently green building is a fun challenge for me!
I am open to suggestions for low-cost improvements. So far, I am thinking:
- Airtight Drywall vapor/air barrier
- Don't add exterior insulation. Just Tyvek under siding (gotta nail those shingles)
- Rigid insulation - strips, or continuous, between framing and drywall, to minimize thermal bridging (1/2"? 1/4"?)
- Heat - on-demand gas heat/HW combination. Perhaps an undersized radiant system ($$), counting on the fireplace to pick up the slack.
- Windows - Low-E on the East, North and West, perhaps max-solar-gain glass on the South. Subject, of course, to finding something close at the local dent-and-scratch discounter.
- Frame, but don't cut, an opening for a future window-style A/C
Any suggestions for the pretty-good-rental?
