How much would my energy bill be reduced if I installed an additional inch of foam insulation over the existing R-11 insulation?
Have a Home Performance with ENERGY STAR evaluation.
The most thorough and reliable way to determine the economic impact of energy-efficiency measures is to have a home energy rating (energy modeling software) conducted on your home by a consultant partnering with Home Performance with ENERGY STAR®. This software program takes into account the air leakage rate, all the surface areas of the shell of your home, and the insulation values in foundation walls, exterior walls, rim and band joists, and ceilings. Windows and doors are accounted for as well as the efficiency of heating, cooling, and water-heating systems. With all the values accounted for, comparisons can then be made to determine their savings potential to help you make informed decisions about upgrades such as you described in your question. In addition, our expert consultants will conduct a thorough inspection of all the mechanical systems in your home and identify performance problems such as air leaks and drafts, moisture, cold spots, and more. You'll receive a detailed written report of the findings and a list of recommended solutions.
Once all work is completed, we'll follow up with a post-performance evaluation and inspection to ensure the improvements are effective. Cash-Back Rewards may also be available for many types of work including insulation and air sealing. Your consultant will complete all required paperwork to make sure you receive any applicable Cash-Back Rewards for the work you've done. Find a consultant in your area and get started today!
