While worn-out window replacement is a common home improvement project, much of the recent attention in this area is focused on Energy Star replacement windows due to the ongoing savings on utility bills that these windows can provide. While many window products claim to be energy efficient, those products with the official Energy Star certification provide homeowners with the assurance that the windows meet rigorous standards for high energy efficiency.
Energy Star replacement windows are tested and rated as such by the National Fenestration Rating Council (NFRC), an independent organization that tests products like windows, skylights, and doors for their energy efficiency. The Energy Star ratings program was implemented to enable consumers to understand the potential savings in HVAC costs from the installation of specific windows and to give consumers a simple method by which they can compare one window product against other windows. Windows rated with the Energy Star certification will perform in a manner that is equal to or above the code for energy efficiency as determined to meet this designation.
To receive the Energy Star certification, Energy Star replacement windows must perform in a manner which will minimize the effects of heat loss and ultraviolet rays in causing the home's heating and cooling system to have to work hard to maintain a comfortable interior temperature. The idea behind Energy Star replacement windows is that those windows that are performing properly will minimize the number of times that the HVAC system needs to be on, as well as reduce the amount of overall time that heating and cooling systems need to run. By reducing the need for heating and cooling, homeowners will experience lower utility bills than they would if they had installed non-Energy Star replacement windows.
Of course, the energy efficiency of any replacement window can be compromised if the installation process is not properly performed. Homeowners need to ensure that the window installer they choose to place their new Energy Star replacement windows is experienced and meticulous in their work. A good place to start to find an effective window installer is the replacement window retailer, but homeowners should do a bit of homework beyond just gathering names and phone numbers. It's always a wise idea to check references for window installers; especially in the case of installing new Energy Star replacement windows, a high-quality contractor can help to ensure that the results will meet or exceed expectations for energy savings.
