SystemVision Materials List
We’ve put the following list together to help you in your materials selection. The first section
includes items that are typically ordered earlier in the construction process, followed by items typically
ordered later in the process, followed by three sections of materials for which sub-contractors are usually
responsible. Use this list as you wish, and please let Advanced Energy know how it could be improved.
Earlier:
- Raised heel trusses, minimum 10 clearance between exterior of top plate and roof deck.
- Windows and glass doors with an overall U-value of .35 or less and an overall solar heat gain co-efficient (SHGC) of .38 or less
- Energy Star® labeled refrigerator or major appliance, if home includes this appliance [Whirlpool-donated HFH refrigerators qualify]
- Water heater, if electric: minimum .93 energy factor (EF), if gas: minimum .61 energy factor (EF)
- Any combustion appliance inside the conditioned space, other than gas ranges and wood fireplaces, must be sealed combustion direct vent or power vented
- No vent free gas logs
- Air-sealing & blocking materials: [Caulk / Sill Seal / Foam / Backer Rod / Thermo Ply / Energy Brace / Blue Board / etc. as needed]

Later:
- Minimum 6 mil. poly to cover 100% of crawl floor
- Minimum two light fixtures with fluorescent lamps. Either T-8 tubular, circular fluorescents or compact fluorescents are acceptable.

HVAC:
- Insulated 6” duct from outside of home to return box within home with manual damper and filter
- Room-by-room load calculation
- Unit sized within ½ ton of room-by-room load calculation
- Split systems matched according to the Air Conditioning and Refrigeration Institute (ARI) directory
- Air flow within ± 10% of room-by-room load calculation
- Bucket mastic to seal all duct connections
- Heat pump specs: minimum SEER 14, minimum HSPF 8.2 with an outdoor thermostat to lock out strip heat above the balance point (~35°)
- Refrigerant charge to manufacturer’s specs
- Inert gas (nitrogen) to braze/solder refrigerant lines
- Furnace specs: minimum 90% efficient
- Pressure balancing: Individual returns, jumper ducts, or transfer grills for each closed room (except baths and laundry), no smaller than the supply air pathway size to the room
|
Electrician:
- Minimum 70 CFM rated fans in baths sealed with bucket mastic to insulated ducts ducted to daylight
- Minimum 120 CFM rated fan in kitchen above range ducted to daylight
- If used, recessed lights must be air tight and insulation contact (IC) rated
- One hard-wired carbon monoxide (CO) detector per 1,000 sq. feet of living space in homes which have any combustion appliance within the conditioned space or which have an attached garage. (min. 1 per floor)

Insulator:
- Wall insulation to meet Energy Star® (dependant on AE’s plan review)
- R-38 attic insulation
