A longtime resident of Columbus, Ohio, Michael "Mike" Lelasher is an experienced construction executive with extensive knowledge of the construction and renovation markets. Michael Lelasher served as vice president of Cardinal Builders from 2004 to 2010, during which he oversaw all day-to-day activities of the firm. The firm receives government tax rebates for energy-efficient insulation and window upgrades.
Data from the US Department of Energy revealed that energy-efficient window upgrades could save $126-$465 annual energy costs for homes with conventional single-pane windows. Homeowners who installed double-pane windows many years ago can also cut up to $111 off their yearly energy bills when upgrading existing windows with modern energy-efficient ones.
Energy-efficient windows reduce energy costs by mitigating heat exchange between a building's interior and outdoors. This miniaturized energy cost comes from a reduced need for artificial heating or cooling. Homes with windows installed a decade ago can benefit from energy-efficient upgrades as technology has evolved significantly since that time. Window manufacturers have rolled out far better energy-efficient windows with more than twice the insulating capacity within the past decade.
Besides reducing energy bills, energy-efficient windows are better barriers to outdoor noise and moisture. Some energy-efficient windows, such as Low-E glass windows, also prevent indoor items' superficial fading from sunlight exposure.
