Energy Efficiency Improvements that Pay You Back!

An accurate and comprehensive energy audit from EverGreen EnergySavers provides you with a common sense and cost effective prioritized action plan for improving building energy performance.

Energy efficiency is more than just about saving money. Energy efficient homes are more valuable because they are also more…

  • Comfortable – with more even room temperatures and less drafts
  • Healthy – with better indoor air quality
  • Durable – with fewer maintenance issues
  • Safer – when done by qualified professionals
  • & Affordable – with greater energy savings

An EverGreen energy audit by a nationally certified RESNET Home Energy Rating System Rater and Building Performance Institute Building Analyst that is based in sound building science and using state of the art technology will lead to wisely chosen energy efficiency improvements through weatherization, insulation and air sealing.

According to the U.S. Dept. of Energy, heating and cooling account for the largest portion of a buildings utility expenses, and air leakage alone can account for up to 40% of these costs, while creating numerous other problems for the building and its occupants.

Energy efficiency improvements are a great investment that cost less than you might think, and will pay you dividends for years to come.

  • I want to thank you for the great job that you did for us. I was able to experience first hand just how much work was involved, and how extensive the project was. If you ever need a commercial reference, please feel free to use Math Reviews.

  • Happy New Year! I just wanted to let you know how pleased we are with the upgrades you did for us at our home. The bathroom fan is amazing! And there is a noticeable difference in temperature between the storage part of the attic and the 'room' part of the attic. So thanks!

    Caitlin L., Ann Arbor
  • EverGreen did a fantastic job retro-fitting our home with the latest energy-saving materials, and sealing the unbelievably many places where heat was flowing out. I had no idea that there were so many ways to tighten and better insulate an old, "leaky" house.

  • No draftiness and the furnace runs less often. Other (my students) notice the music room is very stable in temperature. I especially liked the grouping of improvements and costs so I could figure out what to have done first.

    Jane H, Ann Arbor
  • No evidence of moisture (frost on the wall and floor)...furnace runs less...house retains heat better...Thanks! You may use me as a reference.

  • Hello Nate, Wanted to let you know that my energy usage for mid Feb. - mid March was down from last year for the same period: electric down 34% and gas down 49%. What a difference it made putting in the insulation, changing some lightbulbs, and sealing up the band joists and crawl space.

    DeLynn C, Ann Arbor
  • Hi Nate - Attached below are the electrical and the gas usage comparisons for this house between 2008 and 2009. After Evergreen did the energy conservation work (Feb08), we saw substantial decreases in the gas usage from March 08 and onward...

  • After I had an energy audit by (an insulation company) I added insulation but still noticed a lot of the cold air leaks – Thank you for taking the time to explain to me and show me what was happening (using) your "blower door" – I will be doing air sealing next!"

    Jackie K, Ann Arbor
  • The very first night after (EverGreen) air sealing around our home we noticed such a difference in our daughters' bedroom – what a difference! Thank you!
