As global awareness of energy efficiency and environmental sustainability rises, Des Moines homeowners are seeking ways to reduce their carbon footprint and lower their energy bills. One cost-effective strategy that gets commonly overlooked is upgrading home windows, as people tend to delay getting new windows until visibility becomes an issue. There are a multitude of benefits that replacing your home windows can provide, including: a fresh look, enhanced comfort, and increased property value. However, one of the most compelling advantages is the significant energy savings they can provide.
Understanding Energy Efficiency in Windows
Energy-efficient windows have been around since the late 80’s, and since then, there has been major progress made since then in all aspects of windows. From durability and maintenance to soundproofing and energy-efficiency, modern windows provide a much greater investment in your home than ever before. In the United States, 40% of energy consumption is spent heating and cooling homes, and in Des Moines we are all too familiar with Iowa’s up-and-down weather and the regular increases in energy costs.
The good news is that through energy-efficient windows, we are able to minimize the impact of the weather with the help of various technologies. With glass features like advanced glazing, low-emissivity (Lo-e) coatings, and insulated frames we can reduce our energy consumption for both heating and cooling – making it a great idea for any homeowner.
Quantifying Energy Savings
The potential energy savings from installing new home windows can vary based on several factors:
Window Orientation:
South-facing windows receive more direct sunlight throughout the day, which can impact energy savings. Properly designed windows can utilize this solar heat gain in the winter while minimizing it in the summer.
Window Type:
Single-pane windows are significantly less energy-efficient compared to double-pane or triple-pane windows with inert gas fillings. The number of panes, as well as the type of gas between them, affects a window’s insulation properties.
Frame Material:
Different window frame materials, such as wood, vinyl, aluminum, or fiberglass, have varying levels of thermal conductivity. This can impact the overall energy efficiency of the window.
Sealing and Installation:
Proper installation and sealing are crucial to ensuring that the window’s energy-saving features are fully realized. Improper installation can lead to drafts and air leaks that negate potential energy savings.
What are the Potential Savings?
While exact savings can vary widely, research from organizations such as the U.S. Department of Energy and the National Fenestration Rating Council (NFRC) provides estimates on potential energy savings. According to the NFRC, energy-efficient windows can result in savings of 12% to 33% on heating and cooling costs compared to single-pane windows. In some cases, this could translate to hundreds of dollars in savings annually.
Other Benefits of Energy-Efficient Windows
As previously mentioned, there are other benefits to swapping out your home windows as well – even if there are no cracks or fog on the inside!
Enhanced Comfort:
Energy-efficient windows help maintain a more consistent indoor temperature, eliminating cold drafts and hot spots. This creates a more comfortable living environment year-round.
Noise Reduction:
High-quality windows can act as noise barriers, reducing external disturbances. Pella elevates this further with their noise-reducing technology, providing a peaceful home environment.
UV Protection:
Energy-efficient windows often come with Lo-e coatings that block a significant portion of ultraviolet (UV) rays. This not only helps protect your skin and eyes but also prevents UV damage to furniture, flooring, and artwork.
Increased Property Value:
Upgrading to energy-efficient windows can improve the resale value of your home, as prospective buyers are often attracted to properties with lower utility bills and enhanced sustainability features.
