Talk to your landlord about upgrading your windows

Why? Replacing old windows with energy-efficient windows can lower your heating and cooling costs by preventing air leakage. New windows have many other benefits, including noise reduction and improved comfort, security, and aesthetics.
Benefits to your landlord:
  • Energy-efficient windows will make a rental a more cost-effective and comfortable place to live for current and future tenants.

  • Inefficient windows can cause chronic moisture problems, resulting in mold and other property damage. Upgrading your windows could help your landlord save money by preventing these expensive moisture problems.

  • Recently upgraded windows can serve as an attractive selling point.

Step by step:

  1. Ask your landlord about the age of your windows and whether they are ENERGY STAR® certified.

  2. Encourage your landlord to consider the following features when selecting new windows:

  • ENERGY STAR certification. These are the most efficient option. ENERGY STAR certified windows, doors, and skylights can reduce your energy costs up to 15%.

  • The NFRC® label. This label is used for rating a window's performance, so it will help your landlord in comparing options. Encourage your landlord to look for the following:

    • A low U-value, which indicates the window insulates well.
    • The proper solar heat gain coefficient (SHGC) for your region, meaning the amount of heat transmitted through the windows by the sun.
    • A low air leakage value.
    • A high condensation resistance value, which indicates the window can effectively prevent moisture build-up.
  • The right materials. Wood, vinyl, and fiberglass are more insulating than aluminum for the frame and sash materials.

Actions you can take now:

Landlord not ready for a window upgrade? Try these quick actions to save money and use less energy:

  • Weatherstrip your windows. For many homes, caulking or weatherstripping is the cheapest way to make existing windows more efficient.

  • Improve your shading. Consider shading the exterior of your home with shutters, awnings, exterior solar blinds or solar screening. Just remember that you'll want any exterior shading to be removable during the winter months, when sunlight can help heat your home's interior.

  • Apply window film. This will help block or absorb light and heat all year around.
