Windows
Whether replacing windows in an older house or choosing windows for a new house, your decisions on what type of windows to buy will be among the most important decisions you will make in terms of energy use. In older houses, it is not uncommon for windows to account for a third of the total heat loss from a house.
In new houses, windows typically account for 15% to 40% of total heat loss. Also, those windows can account for as much as 75% of heat gain during the summer months, adding to air conditioning costs. On the positive side, windows can be used for passive solar heating in the winter months and help reduce heating cost, and of course windows provide natural day lighting and view to the outside world.
Because of the impact windows have on both heat loss and heat gain, proper selection of products can be confusing. To add to the complexity, window-glazing technology has changed tremendously in recent years. The best window glazing today insulate almost four times as well as the best commonly available windows from just fifteen years ago.
Because of the rapid pace of change, even skilled designers are often not fully aware of the potential these new glazing offer for energy-efficient building design. Fortunately, just as windows were becoming more complicated, two organizations began offering better data and guidance for consumers. The National Fenestration Rating Council (NFRC) provides the objective data for wise choices, and ENERGY STAR offers guidance tailored to your climate zone.
Green Home Pros has teamed up with Silverline windows by Anderson Company as part of its system. GHP believes that Silverline gives energy savings at a reasonable cost.
