1. Those with a peak design rate of energy usage less than 3.4 Btu/h - ft' <br /> (10.7 W/m2) or 1.0 watt/ft'(10.7 W/mz) of floor area for space- <br /> conditioning purposes. <br /> 2. [ ] Unconditioned space that <br /> does not contain habitable space. <br /> 3. Unconditioned dwellings with enclosed habitable areas less than 1,100 <br /> square feet." <br /> 4. Dwellings with permitted, off-grid, self supplying photovoltaic with <br /> battery back up." <br /> (32) TABLE R402.1.2 of the International Energy Conservation Code is deleted in its <br /> entirety and replaced with the following: <br /> "TABLE R402.1.2 <br /> INSULATION AND FENESTRATION REQUIREMENTS BY COMPONENTa <br /> WOOD CRAWL <br /> CLIMATE FENESTRATION SKYLIGHT GLAZED CEILING FRAME MASS FLOOR BASEMENT SLAB SPACE <br /> ZONE U-FACTOR° U-FACTOR FENESTRATION R-VALUE WALL WALL R-VALUE WALL R- WALL <br /> b SHGC b,c,g ° R-VALUE d R-VALUE R-VALUE VALUE R-VALUE <br /> j-f &DEPTH <br /> I NR 0.75 0.25 30 13 314 0 0 0 0 <br /> For SI: 1 foot=304.8 mm <br /> a.
