Weatherization, Including Air Infiltration and Duct Efficiency Measures

Air Infiltration

Warm air leaking into your home during hot summer months and cold air infiltrating your home during the winter time can cost you a lot of money! One of the easiest and most cost effective measures to reduce your energy bill is to have Green Collar Operations perform weatherization including the following air infiltration measures

HERE IS WHAT WE PERFORM:

Air Infiltration Measures **- The following measures may be taken to seal windows, doors, plumbing penetrations, furnace closets, light switch and outlet gaskets etc:

  • Sealing Furnace Closet (if there is one)
  • Sealing Plumbing Penetrations (where plumbing penetrates walls)
  • Window Caulking
  • Door Weather Stripping
  • Sealing Attic Access
  • Light Switch and Outlet Gaskets

Here is a pie chart which will give you an idea of where some of those "unknown leaks" are coming from:

Duct Efficiency

Leaky ducts have remained an invisible energy culprit for years. In fact, researchers at the US Department of Energy and their consortium, REEDS (Residential Energy Efficient Distribution Systems) have found that duct efficiency may be as low as 50 70%. In Austin TX, Austin Energy has stated that the average 25-year-old home has duct work that is leaking on average about 30% of cooling into the attic. By simply making residential ducts more efficient, the US Department of Energy has stated that energy saving in the magnitude of 90 Billion kWh plus 9 Billion terms could be achieved along with significant reduction in peak loads. Because of this, Green Collar Operations has focused on helping local homeowners reduce their energy bills through improved duct efficiency measures.

HERE IS WHAT WE PERFORM:

Duct Efficiency Measures **- The following measures may be taken to seal the duct system so that the air circulates from the return(s) through the system and back into the home with minimal to no air loss into the attic, garage or any other non conditioned space in the home.

  • Sealing the air handler/ furnace
  • Sealing return(s)
  • Sealing Plenum(s)
  • Sealing all registers & duct connections

Some of the benefits of duct sealing and insulation include:

  • Increased comfort levels by not allowing the house to become too cold in winters or too hot in summers thereby improving energy efficiency.
  • Reduction in air pollutants entering inside the ducts and into the house.
  • Often during normal usage of gas appliances, carbon monoxide enters through the ventilation systems. The carbon monoxide then leaks through the ducts and into the home causing air pollution. Sealing ducts can reduce these harmful gases from entering your home
  • Significant cost savings through lower utility bills.
  • Sealing ducts reduces greenhouse gases and assists with energy conservation as less energy is being utilized for heating and cooling of your home.

Why Is Duct Leakage An Important Measure To Perform?

  • Leaks in the supply ductwork result in air loss into the attic, crawlspace or garage instead of into the house.
  • Return leaks pull outside air into the duct system reducing both efficiency and capacity. In humid climates, moist air being drawn into return leaks can even overwhelm a new system's cooling ability.
  • The dehumidification capacity of air conditioning systems causing homes to feel clammy even when the air conditioner is running.
  • Heat pumps are particularly susceptible to comfort complaints from duct leakage, especially during the heating season. Duct leaks can cause the air coming from heat pumps to feel luke-warm or even cold during the winter. In addition, leaky ductwork has been found to greatly increase the use of electric strip heaters in heat pumps during the heating season.
  • Leaks in return ductwork draw air into the house from crawlspaces, garages and attics bringing with it dust, mold spores, insulation fibers and other contaminants.
  • Household depressurization from duct leaks and imbalanced duct systems can cause spillage of combustion products (from furnaces, water heaters and fireplaces) into the house.
