According to ENERGY STAR, a federal government program, replacing older windows with new high-efficiency windows will save homeowners an average of $400* a year in the Mid-Atlantic region.
And, as heating costs rise, those savings increase! Heating oil may increase 10%, costing the average customer $193 more this winter. Additionally, increases in propane and natural gas prices are also expected to increase home heating bills this heating season.
Because of volatile energy prices, homeowners will see a great benefit this year by replacing old windows with new high-efficiency windows to cut down on energy usage.
If your home is over 10 years old, your windows may be outdated: windows have become more technically advanced. With new high-efficiency windows, it is now possible to have lower heat loss, less air leakage, and warmer window surfaces that improve comfort and minimize condensation – saving the average homeowner in the Mid-Atlantic region $400* a year.
Additionally, depending on the condition of the existing windows in your home, the annual heating savings can be even greater if new high-efficiency replacement windows reduce long-term air leakage.
*U.S. Department of Energy. Savings is for homes in the Middle Atlantic region when replacing single-pane windows. Estimate savings based on an even mix of one- and two-story detached homes of 1700 or 2600 sq. ft. respectively, with 15% of their floor space in windows that are equally distributed across compass directions. Heating and cooling systems are modeled as either natural gas heat with electric air conditioning or electric heat pump, according to the regional breakdown reported in the Energy Information Administration’s (EIA) 2005 Residential Energy Consumption Survey. Estimates use the EIA’s 2006 average natural gas prices and 2007 electricity prices. Actual savings will vary by local climate conditions, utility rates, and individual home characteristics. Hawaii was excluded from this analysis, as the assumptions in the standard software program used for calculating the impact of windows on heating and cooling costs for the residential sector diverge significantly from the norm in Hawaii and may apply in certain circumstances.
