Storm Window and Insulating Panel Campaign

This campaign is a collaborative initiative to accelerate the adoption of high-efficiency storm windows and insulated window panels, delivering energy savings and comfort in residential and commercial buildings at a fraction of the cost of full window replacements.

Older, inefficient windows waste energy and cost consumers and businesses millions of dollars every year in heating and cooling costs. Retrofitting these windows with window attachments or installing new high-performance windows not only saves energy, but also improves indoor comfort. The U.S. Department of Energy and its partners are collaborating to introduce the Storm Window and Insulating Panel (SWIP) Campaign. Storm windows and insulating panels are attached to the interior or exterior of primary windows to provide air sealing, thermal insulation and sound attenuation benefits and other benefits at a fraction of the cost compared to full window replacements.

 

How it Works

The U.S. Department of Energy (DOE) is working with partners on new collaborative initiatives to accelerate the adoption of high-efficiency storm windows and insulated window panels.

The SWIP Campaign is focused on speeding the upgrade of old, inefficient single and double-pane clear glass windows with ENERGY STAR certified storm windows, or with Attachments Energy Rated Council (AERC) rated insulated panels in commercial buildings. Storm windows are an affordable option for homes where full window replacement may not be feasible, such as lower-income households, multi-family households, households working with U.S. Department of Housing or weatherization programs, or households in historic preservation districts. The SWIP Campaign works with stakeholder partners, including utilities and efficiency groups, contractors, weatherization programs, energy service companies, product suppliers and manufacturers, trade and professional groups, program implementers, and others who support the Campaign’s goals. The Campaign serves as a national platform to host research and useful resources, including field demonstration results, case studies, and utility program best practices, and to recognize successes. Participants in the Campaign can be recognized for taking action to install high-efficiency storm windows and insulating window panels, and for achievements related to innovative program approaches, impactful marketing campaigns, innovative training and educational resources, and more.

Why it is Important

Of the nearly 40 quads of primary energy used in residential and commercial buildings each year1, just over 40 percent is attributed to heating and cooling buildings. Over half U.S. homes have single-pane windows or double-pane clear glass windows, which are inherently inefficient and poor insulators, and about 40 percent of commercial buildings have single-pane windows. Field demonstration have confirmed year-round HVAC system energy reductions of 10-30 percent in homes with single-pane or double-pane clear glass windows. These savings compare to double-pane window replacement savings, but at the third of the cost and payback periods as low as 4 years. Installation is relatively easy, with 80 percent being DIY installations. Other benefits include added comfort, operability, acoustic improvements, and aesthetic appeal. Similar benefits can be achieved in the commercial sector, where single pane or double-pane clear glass windows are common in older buildings. In addition to energy savings at lower cost, building owners who upgrade their windows offer their employees and tenants improved comfort and other benefits. The U.S. Department of Energy estimates that if all single pane and all double pane clear glass windows in the U.S. were upgraded with low-e storm windows and insulating window panels, homeowners and businesses could collectively save over a quadrillion Btu of energy and $20 billion per year.

How Partners Benefit
