Undertaking a major renovation, remodeling project, or addition is also a great opportunity to make energy efficiency improvements that can make your home more comfortable and reduce your energy bills. That's because these remodeling projects often involve replacement or significant alterations of walls and roofs, windows, heating and cooling systems, ductwork, lighting, and/or appliances that can all have a big impact on your home's energy use. This is a particularly good time to undertake improvements such as sealing ducts and adding insulation in walls that otherwise could not be done easily or cost-effectively.

You might consider hiring a Home Energy Rater to help you evaluate your home’s current status, review your renovation plans, and make suggestions on ways to make the project (and the rest of your home) more energy efficient. Find Home Energy Raters in your area.
