Building Shell - Windows
!

Note: Sealing a home too tightly can result in a decrease in indoor air quality and other adverse conditions. A professional home energy auditor can measure ventilation in a home and recommend appropriate air sealing measures. A consultation with an auditor is recommended before sealing the home to a significant degree.

Gaps around flues or chimney shafts

Gaps around plumbing or electrical penetrations, vents, wall- or window-mounted air conditioners, baseboards, and floor joist-to-foundation junctions

Other noticeable gaps in building shell

!

Other air leaks may be found in or around attic hatches, attics above dropped ceilings, and in common walls between an attached garage and the home.

x

Insulation - Attic/Roof

Insulation - Other
!

Recommended R-values may not be valid for the coldest climates of Colorado. Air sealing should be performed prior to insulating. The following R-values are approximate and may vary based on quality of installation and other factors: Fiberglass batt = 3.2/inch. Loose fill fiberglass = 2.5/inch. Loose fill cellulose = 3.7/inch. Mineral wool = 3.1/inch. Expanded polystyrene = 4.5/inch. Extruded polysyrene = 5.5/inch Polyurethane/polyisocyanurate = 6.5/inch

Possible Condition Rating Recommendation Cost Notes

Floor insulation less than R-25

!

If over unheated, uninsulated space.

x

Exterior wall insulation less than R-18

!

Turn off electric power to exterior wall outlets, remove outlet cover, and feel for insulation with pencil or similar. Otherwise, drill a hole through the wall in an inconspicuous location. To judge the insulation of walls throughout the entire home, a professional energy audit is required.

x

Crawlspace wall insulation less than R-19

!

If crawlspace is unvented and the floor above the crawlspace is uninsulated.

x

Basement wall insulation less than R-11

Pipes are uninsulated

Ducts not properly sealed and/or insulated

!

Ducts should be sealed with liquid mastic - not duct tape - at all joints, seams, and attachments. For reference, older mastic can look like gray peanut butter. Also note that sealing and insulating ducts in unconditioned spaces where pipes are present can result in frozen pipes. Insulating the ducts, pipes, and the unconditioned space itself is recommended in this situation.

Heating and Cooling
Possible Condition Rating Recommendation Cost Notes

Solar heat not let in through open window coverings in cold months

Windows not open to allow cool air in and closed to keep warm air out in summer

Vents, baseboards, radiators, space heaters blocked

Furnace filter dirty/not cleaned or replaced every 1-3 months when heating

Furnace or boiler less than 90% AFUE

!

AFUE = Annual Fuel Utilization Efficiency and can be found on the heating unit label.

Air conditioner not cared for regularly/properly maintained

Air conditioner inefficient/expensive to operate

Thermostat not used for energy savings

No thermostat installed

Water Heating
Possible Condition Rating Recommendation Cost Notes

Water temperature greater than 120 degrees

!

Water temperature should be measured at the faucet closest to the water heater as the temperature dials on the heater aren't always reliable.

x

Dishwasher not run when full

Clothes washer run on hot

Showerheads emit greater than 2 gallons per minute

!

The most accurate way to measure flow is to run shower water into a 5 gallon bucket for 1 minute and measure the amount.

x

Electric storage water heater hot to the touch

Gas storage water heater hot to the touch

Water heater inefficient

!

Efficient gas storage heaters have Energy Factors of 0.65 or more; efficient electric storage heaters have Energy Factors of 0.9 or more.

x

Lighting
Possible Condition Rating Recommendation Cost Notes

Incandescent or halogen bulbs in use

T12 lamps and magnetic ballast in use

!

T12 bulbs are linear tubes (not compact), are usually found in a fixture attached to a ceiling surface or in a ceiling panel, and are 1.5 inches in diameter.  Magnetic ballasts can be detected by borrowing a “flicker checker” from a participating County Extension office.

x

Appliances
Possible Condition Rating Recommendation Cost Notes

Refrigerator temperature less than 38 F

Freezer temperature less than 0 F

Refrigerator coils dirty/dusty

!

A phantom load is electricity used by appliances even after they're turned off. They are present in appliances that remain lit when off, that have external power adapters, and that are controlled by remotes. Phantom loads can be measured by power monitors available on loan at many libraries and Extension offices.
