Window Energy Savings
According to efficientwindows.org, quality replacement windows will save approximately $868 per year in northern US climates (such as Grand Rapids, MI) where the winter is often harsh driving heating bills up to astronomical numbers. These numbers are backed by scientific research, and include appropriate climate factors into their algorithm. So if you pay $7000 for a house full of quality replacement windows, you can expect to recoup that in around 7.5 years or less depending on what inflation you estimate we experience on energy costs! Note that when new windows are installed improperly, you can actually lose energy efficiency, or reduce the efficiency that your new windows were designed to offer. Make sure you have an energy star approved and tested window, and an AWDI certified installer company like us.
If your home has very old and/or inefficient windows, it might be more cost-effective to replace them than to try to improve their energy efficiency. New, energy-efficient windows eventually pay for themselves through lower heating and cooling costs, and sometimes even lighting costs.
The above quote is from: http://energy.gov/energysaver/articles/energy-efficient-windows
Windows and doors are typically responsible for about 40 percent of your home’s heating bill. Thermal windows are typically two to four times more efficient than older single pane windows. That means you can expect your winter heating bills to drop on average about 20 percent to 30 percent. The bigger your fuel bills and the draftier your old windows, the quicker your new windows will pay for themselves
Angie Hicks, Angie’s List founder: “My favorite home improvement projects revolve around energy efficiency and window replacement is a great example. If you replace your windows you can save as much as 30 percent on your heating and cooling bills.
Roofing Energy Savings
When we talk with people about roofing in Grand Rapids, a surprising number don’t realize that s roofing system can save them money on energy costs. With energy costs predicted to continue rising sharply, this should be considered when looking at a new roofing system. Many homes, and in some neighborhoods most, do not have proper ventilation for their roof. Few companies mention that this actually voids shingle manufacturer warranties in most cases, greatly reduces the life of the roof, and people end up heating their attic repeatedly in the winter. With proper ventilation and sufficient insulation, the energy savings can be huge and your roof can look new longer!
