  • Did you know about Naperville’s Window Replacement grants?
Rick September 20, 2023 0 Comments

Windows are a big investment for your home, but the City of Naperville can help!
By improving your homes Energy efficiency your HVAC will run less in the summer and wintertime reducing your consumption of electricity, gas and stress on our supply infrastructure. By reducing our demand of natural resources it will improve our environmental conservation at the same time.
There are stipulations to the program, such as you must be upgrading from single pane windows and be a part of their Renewable Energy Program. Getting away from single pane windows is so beneficial, the city felt it was worth creating this grant system.

Single-pane windows are less energy-efficient than double or triple-pane windows, which means they can contribute to greater energy loss in your home. Here are some of the ways single-pane windows can result in energy loss:

  1. Heat Transfer: Single-pane windows provide less insulation compared to multiple-pane windows. During the winter, they allow heat to escape from the interior of a building to the colder outside, resulting in higher heating costs.
  2. Cooling Loss: In the summer, single-pane windows allow heat from the outside to enter the home, making it harder to keep the interior cool and make the Air conditioner run harder and longer.
  3. Noise: Single-pane windows offer less sound insulation compared to thicker, multi-pane windows. So you’ll hear more noise from outside your home.
  4. Drafts: Older single-pane windows may develop drafts over time as the seals deteriorate or the window frames warp. This can result in uncomfortable drafts and increased energy loss.
  5. UV Damage: Single-pane windows typically do not have coatings or gas fills to block ultraviolet (UV) rays. UV rays can fade and damage furniture, carpets, and artwork.

To mitigate these issues and reduce energy loss, It’s a worthwhile upgrade to double or triple-pane windows. These windows have improved insulating properties and can significantly enhance energy efficiency and comfort. While the initial cost of replacement windows can be high, the long-term energy savings and increased comfort can make them a worthwhile investment. And with the Naperville Grant program will help with your costs. Here’s information on how to prepare for applying for the grant.

RESIDENTIAL ENERGY EFFICIENCY REBATES

The City of Naperville Electric Utility is offering rebates for homeowners who install energy-efficient attic insulation and replace single-pane windows.

  • To qualify for the rebate, applicants must be residential Naperville Electric Utility customers who own or rent their residence.
  • 100% complete applications/documentation must be received within 120 days of installation. 
  • The rebates are limited to 50% of the project, including material and installation, with a $3,000 maximum rebate for each energy-efficient improvement.
  • Customers could qualify for a maximum rebate of $6,000, if they installed both attic insulation and energy-efficient windows.
  • Rebates will end when all funding is allocated. Projects PURCHASED OR INSTALLED in the calendar year when all funding is expended will NOT be eligible for future incentives.  
  • Applicants must provide a copy of their current utility bill showing they are a contributor to the Renewable Energy Program at the $5-per-month level or above. Renewable Energy Program contributions are the source of funding for these rebates. For more information and to sign up for the program, visit www.naperville.il.us/renewable.

WINDOW REPLACEMENT

Windows must have a U-factor of 0.30 or lower.

  • The grant amount is $300 per window, with a $3,000 maximum award.
  • The window must separate a heated space from an unheated space and must replace a single-pane window with a double or triple-pane window.
  • Homeowners must submit close-up photos of each existing single-pane window replaced to document all windows are single-pane. 

According to the Department of Energy, heat gain and heat loss through windows are responsible for 25% to 30% of residential heating and cooling energy use. For windows, the rate of heat loss is indicated in terms of the U-factor. The lower the U-factor, the greater a window’s resistance to heat flow and the better its insulating value.

Here are some tips for applying for the window replacement rebate.
