 | 1. Knee Wall Provisions - Inadequate coverage
- Improper materials – not an air barrier
- Incorrect number or type of fasteners
- Improper framing that allows air to move through the insulation
|
 | 2. Slab Insulation - Missing insulation
- Insulation not in contact with the slab
- Improper attachment of insulation with the slab
- Insulation damaged during installation
- Poor finishing details
|
 | 3. Lighting - Fewer than 75% high efficacy bulbs
- Fixtures selected for which high efficacy bulbs are difficult to find
|
 | 4. Ductwork Sealing and Design - Excessive leakage from air handling unit and connections for supply and return plenums
- Takeoffs not sealed properly
- Supply boots not sealed properly to incoming duct or to the floor
- Toe kick registers cannot be sealed
- Filter boxes that are not sealed
- Wall framing used as return and unsealed
|
 | 5. Air Sealing and Air Barriers - Dropped soffits/ floor systems
- Floor cavity under knee walls – missing blocking or poorly sealed
- Chases
- Garage-to-house connection
- Porch roof to house connection
- Wall top plate
- Incomplete backer intended to cover the insulation
|
 | 6. Floor Insulation - Insulation not in contact with air barrier
- Insulation not well secured
- Missing insulation around ductwork, electrical wiring and fixtures, plumbing, and other locations
- Incomplete coverage under cantilevered floors
|
 | 7. Wall Insulation - Insulation has gaps, voids and/ or compression
- Poor installation around electrical wiring and boxes
- Missing or loose insulation at band joists
|
 | 8. Attic Insulation - Missing attic insulation card
- Missing attic rulers
- Attic insulation batts with gaps and voids
- Missing weatherstripping around attic hatches or stairs
- Missing or poorly attached attic hatch or stair insulation
- Site-built knee wall doors not insulated to R-5
|
 | 9. Energy Efficiency Certificate - Certificate missing
- Certificate not fully filled out
- Certificate not signed by builder, permit holder, or registered design professional

 | 10. Beyond Code Best Practices – Advanced Framing - Orientation of blocking creates a bridging effect at:
- Ladders at T-wall intersections
- Joints in sheathing
- Corner framing interferes with insulation
- No insulation in headers
