The Retrofit

 

Retrofits for homes participating in the HELP program are performed by prequalified Building Performance Institute (BPI) Certified Air Leakage Control Installers. BPI (www.bpi.org) works through local area training providers to provide certification programs based on building science principles and home performance standards that are supported by the Home Performance with ENERGY STAR® program from the Department of Energy (DOE) and the Environmental Protection Agency (EPA).

Retrofit work is primarily focuses on safety, reductions in air leakage in the envelope and duct system, insulation installation or upgrades, and other efficiency improvements recommended by the Building Analyst.

Home energy retrofits can be achieved at various levels and at varying costs. Listed below are four levels and cost ranges to consider:

  • Low/No Cost Retrofits = Instant return on investment (ROI)
  • Turn off lights and electronics when leaving a room.
  • Turn down water heater thermostat to 120°F.
  • Inexpensive Retrofits = ROI Within 1 Year
  • Install water efficient faucet heads for your kitchen and bathroom sinks. 
  • Install a programmable thermostat and use it. 
  • Replace incandescent light bulbs with compact fluorescents
  • Replace furnace filters every 400 hours of use
  • Affordable Retrofits = ROI Within 1-3 Years
  • Seal all leaks identified by a blower door test. Start with the attic and crawlspace/basement first (especially around plumbing and electrical penetrations) then weatherize windows and doors.
  • Seal and insulate air ducts.
  • Attic: increase attic insulation to R-38
  • Crawlspace: install R-19 insulation in the crawlspace
  • Deep Retrofits = ROI Within 5-10 Years
  • Walls: adding wall insulation is more difficult and expensive, but may be cost-effective if your house is uncomfortable.
  • Replace old single pane windows with more efficient double pane, insulated windows.
  • Upgrade your water heater, furnace/boiler, air conditioners, and appliances to more efficient models. Newer units may be far more efficient.

Sealing top plates in walls

  • A top plate is a wood member that forms the top of a framed wall. 
  • Some top plates have plumbing or electrical penetrations that are commonly left unsealed in regular construction practices.  This allows for the exchange of air between the attic and the wall cavities. 
  • All top plates should be sealed, followed by sealing all other penetrations to improve the indoor air quality, reduce heating and cooling costs by reducing drafts, and help reduce humidity issues

 

Duct Work

  • Kidd audit 010 DSC01484
    Sealing before
    Properly sealed ductwork
    In homes with forced-air heating and cooling systems, duct systems are used to distribute the conditioned air throughout the house
  • If your home’s duct work was not installed or sealed properly, you could be losing a significant amount of conditioned air to unnecessary areas like attics, walls, and crawlspaces.
  • The result of leaky ducts is higher energy bills due to low efficiency in moving conditioned air.  If the duct system is too bad, you may not be able to control temperatures in certain parts of your home no matter how you set the thermostats.

 

Attic Insulation

    Attic insulation is a very important part of a homes thermal barrier.
  • In the winter, as hot air rises in the home it can be lost by conducting through the ceiling into the attic space.  In the hotter months, attic temperatures can reach 150 degrees F.  This extreme heat can transfer through an un-insulated ceiling and make it difficult and costly to keep the home as cool as desired
  •  In our region the US Department of Energy recommends a minimum of 12” of attic insulation.  This would give the home a minimum R-value of 38
  • In homes with little or no attic insulation, adding the required amount can be one of the most cost-effective energy saving measures.
