​In many cases, the first step contractors will take is to perform a home energy assessment (or an energy audit), which will identify the top priorities for reducing your home's energy use. A certified energy auditor can examine your home's insulation, air tightness, heating/cooling systems, and other sources of energy consumption. This diagnostic testing can help determine the best ways to upgrade your home's energy performance and provide guidance on taking a whole-house approach. 

Home energy assessment are an easy way to learn how you can save energy and money and create a healthy and comfortable home. During an energy audit, a professional energy analyst examines each room of your home to provide energy-saving recommendations tailored to you. They will identify which home projects can save you the most money and energy, and may offer to do some minor repairs or upgrades for you, such as changing light bulbs to LEDs. 

According to the Department of Energy, implementing the energy upgrades recommended in a Home Energy Audit can save anywhere between 5%-30% on your monthly energy bill. These improvements will also lead to increased comfort — a warmer home in the winter and a cooler home in the summer. Finally, many of these improvements lead to improved air quality and a healthier, safer home. 

Hire an Energy Auditor

  • DTE’s low-income programs allows you to schedule an appointment with a DTE Energy Specialist, who will come to your home for a basic walk-through. They will check windows and doors, ventilation and home energy use for adequate efficiency, and install free energy-efficient products. 

Perform a Preliminary Assessment (DIY) 

W​hile ​a professional home energy assessment is the best way to determine where your home could improve its energy efficiency, you can conduct your own walk-through and spot many problems within your home. This "do-it-yourself" home energy assessment can help you pinpoint some of the easier to address issues. Create a thorough checklist of areas you have inspected, and problems found during your walk-through assessment, to help prioritize which energy efficiency upgrades to perform.
