Ventilation: The ventilation system has been checked for proper operation. If designed for intermittent operation, the system is controlled automatically by a time-of-day timer set to run for a minumum of eight hours per day. If designed for continuous operation, the system is directly wired to a dedicated circuit in the electrical panel. Make-up air: Ports or registers supplying outside air in the quantity of 10 CFM are located in each bedroom and the main living area. Radon monitor: Radon monitor supplied to residents. Exhaust duct insulation: All exhaust ducts in unheated spaces are insulated to R4 . -------------------------------------------------------------------------------- _______________ Page 3 WATTSUN 5. 3 COMPONENT CHECKLIST 02/25/80 FILE: C: \WATTSUN5\NEWFILE HOUSE ID: PLAN 1516 Name: SAME Floor Area: 1516 ft2 Address: Heating Type: Electric: Zoned Reference: 1991 WA State Energy Cde ---------------------------------------------------------------------- FRAMING INSPECTION --------------------------------------------------------------------------- Approved plans: Are available onsite Air leakage: Soleplate is caulked or glued to subfloor. Rim joists between stories are caulked/sealed. All holes in building envelope (i.e. exterior ceilings, walls, and floors) are caulked/sealed, including all electrical, plumbing, j and HVAC penetrations. Outlets, switch boxes and recessed fixtures on exterior walls are caulked/sealed with approved sealant, or have foam face gaskets installed. Any recessed lights are IC rated, air tight, and sealed to the ceiling sheetrock. Wall framing: Net wall area: 1278 ft2 Standard framing with studs spaced 16" o.c. Structural panels: All structural sheathing is stamped "Exposure I" or "Exterior" . Windows: (MILGARD PW AR/LE VINYL 8 . 0 ft2) (MILGARD SL AR/LE 128 . 0 ft2) (MILGARD SGD AR/LE VINYL 42 . 0 ft2) Windows are installed as shown on the approved plans. The rough opening around windows and doors is caulked/sealed. Exhaust fans, spot ventilation: Bathroom fans are 50 CFM, kitchen fans are 100 CFM. Fan ducting has minimal bends and terminates outside of the building. The whole house exhaust fan is between 80 and 120 CFM. The whole house fan is rated at 1. 5 sones or less (unless remotely located) . INSULATION INSPECTION ------------------------------------------------------------------ Wall insulation: (R19 STD T1-11 1278 . 0 ft2) Insulation fills all exterior wall cavities. It is not compressed and is cut to fit around wires, pipes, and outlet boxes. Recessed Page WATTSUN 5. 3 COMPONENT CHECKLIST02/25/80 FILE: C: \WATTSUN5\NEWFILE HOUSE ID: PLAN 1516 fixtures in exterior walls have at least R-5 insulation behind them. j Vapor retarder: 1. 0 perm or less vapor retarder (e.g. poly, kraft j paper, perm rated paint) is installed on the warm side of insulation in floors, ceilings and walls. Air sealing: A continuous air barrier is installed over the entire inside surface of exterior ceilings, walls, and floors. Recessed lights: Any recessed light fixtures in the thermal envelope are certified under ASTM E-283 and labeled showing compliance, or are sealed around the exterior to be air tight. FINAL INSPECTION --------------------------------------------------------------------- Crawl space moisture barrier: A six mil black polyethelene ground cover is installed on crawlspace floor. Floor Insulation: (R38 vented Joist 16oc 1516. 0 ft2) Insulation is supported in a permanent manner without compression. Crawlspace ventilation: At least 5. 1 Ft2 of net free ventilation is provided in the vented crawlspace. Pipe insulation: All water pipes in unheated spaces are insulated to R-3 . Hot water: Electric water heater labeled as meeting ASHRAE Standard 90A-1980 or 1987 NAECA. Tank has R-10 non-compressible pad underneath if located over slab or in unconditioned space. Shower heads allow a maximum flow rate of 3 . 0 gallons per minute. Doors: (STANLEY 6 PANEL METAL DOOR 21. 0 ft2) Weatherstripping, threshhold, and doorsweep are properly adjusted and seal well. Ceiling: (R49 blown Attic STD baffled 1516. 0 ft2) Insulation is installed to the manufacturer's recommended density and coverage. Attic access doors are insulated and weatherstripped.
