Replacement windows are a popular and sensible home improvement for many homeowners. Starting with an in home energy analysis by Renewal by Andersen can help you in several ways when deciding about a window upgrade for your home. A home energy audit gives you important information about how efficient your existing window are in saving energy. Information from an energy audit then helps you choose the right windows for your home when replacing the old ones.
Replacement windows come in many grades of energy efficiency, materials, and architectural styles. All of these factors contribute to the final cost of the window. Knowing what grade of window you really need by having an audit done first keeps final replacement costs down.
In addition, having an energy audit also tells you about other ways of improving the energy efficiency and comfort of your home.
An energy audit done by Renewal by Andersen is a comprehensive evaluation of how much energy your home is losing in its current state, particularly through your windows. During this test, energy auditors will accurately measure for air leakage around windows.
Replacing old windows is most important in homes with existing single-glazed windows. Double glazing, now required by the building code almost everywhere, both keeps heat in and out, improving comfort and energy efficiency in both winter and summer.
In some climates, triple glazing is a worthwhile investment. The space between the glass in both double and triple glazed windows can also be filled with a gas like argon, adding to the thermal efficiency of the window. A comprehensive energy audit lets you fine tune which type of window is really best for your home.
Energy audits go beyond detection of leaks; a comprehensive audit also evaluates home utility bills for a 12 month period and compares them to averages for similar households, giving you a picture of how your home stacks up against other households in energy use. An energy audit may also take into consideration insulation in the attic and basement or crawl area, and furnaces and duct work when providing estimates of energy savings.
When I had my windows replaced in Philadelphia, the local Renewal by Andersen energy auditor asked relevant questions about times of day when the residents were home, room use, and preferred thermostat settings. All of this information is part of the final calculation of how effective replacement windows will be for your home and which grade of energy efficiency will give you the best results.
Renewal by Andersen has new windows in a wide range of styles, including double hung, casement, sliding, bay, and patio. All of these windows have Energy Star® rating labels, making it easy to measure just how much energy savings each window offers.
Installing replacement windows reduces energy bills by up to 15 percent. A 2015 survey by the National Association of the Remodeling Industry (NARI) and National Association of Realtors (NAR) also found that homeowners who replace windows in their home recouped an average of 80 percent of the cost through the additional value the new windows bring to the home’s sale price.
Another interesting result of this same study found that window replacement is among the top remodeling projects when it comes to homeowner satisfaction with the end result. On a satisfaction scale with a low of 1 and a high of 10, survey respondents rated window replacement at 9.2.
An in home energy analysis is a sensible place to start when considering home window replacement.
