It’s a very fair question to ask how much you can expect to save on your energy bill by replacing your windows. After all, the benefits must necessarily outweigh the cost, or it wouldn’t be worth the investment. Well, there are many factors are involved in determining the energy savings you will see when you upgrade the old windows in your home to energy-efficient windows. I have been in this business for 18 years and have seen savings vary, but everyone saves a significant amount. Out of the last 4,000 window jobs that I have been involved with, I have had clients tell me they have saved 26%, 33%, 52%, and so on.
There is no doubt that you will save money on your utility bill by installing insulated replacement windows. But exactly how much is a very tricky question. Let’s focus on some of the key factors involved that will change your energy bills.
How light and heat enter your home can determine how much you can save on utilities by upgrading your windows. For example, if you have no trees to block the sun and many large windows on the south side of your home, with no eaves or overhangs, energy efficient windows will reduce your cooling costs in the summer significantly. If you have windows on the west side where the setting sun shines into your dining room at the end of the day, upgrading your windows will make dinner much more comfortable. In comparison, if you have a porch or deck with 36” overhangs or a patio cover, which protect from the sun, replacement windows will have less of an impact.
I have had clients brag about rooms in their home that they can actually enjoy using again after getting new windows. New windows that block UV rays can also keep your carpet, floors, and pictures from fading out in rooms that get the most light.
Calculating the energy savings from replacement windows involves several factors, including the type of window, the size of the window, the climate where you live, and the energy costs in your area. Here's a general formula you can use to estimate your potential energy savings:
For a more detailed calculation, you can use the following formula:
It's important to note that these calculations are estimates and the actual energy savings you achieve may vary based on several factors. It's recommended to consult with a window expert or use an online calculator to get a more accurate estimate of your potential energy savings.
Whether or not it is worth the investment to replace your energy-efficient windows depends on a variety of factors. Here are some things to consider:
In summary, if your current windows are old and in poor condition or you are experiencing high energy bills due to air leaks and poor insulation, it may be worth the investment to replace them with energy-efficient windows. However, if your current windows are in good condition and you are not experiencing high energy bills, it may not be necessary to replace them at this time.
Even though there is no set scientific formula, it is easy to see that some people will save more than others when installing replacement windows, but everyone will certainly benefit from them. If you choose a high quality window and have a well-qualified, professional, experienced installer install the windows, you can expect a minimum of 25% and a maximum of 52% savings on your energy bill. For example, you may spend $10,000 on replacement windows but end up saving around 40% of your annual $3000 energy bill, amounting to a savings of $1200 a year. Not only will your savings end up paying for the cost of the windows, but more importantly, you will experience a more comfortable home with enhanced beauty and value. You will also have a greater appreciation for your home and will want to show off your new windows, and probably brag to your friends and neighbors about your magically reduced utility bills.
