ENERGY STAR … in three simple steps

We help homebuilders save time and money as they build a high performance green home that will sell for a higher price! 

1. We start by reviewing plans with energy analysis software to provide a “projected rating” – an indicator of the homes efficiency. A rating based on plans and specifications tells the builder or homebuyer if the house qualifies for an ENERGY STAR rating. In the event it does not, then options can be considered while still in the planning stage. Precise heating and cooling load calculations often permits smaller equipment, leading to builder savings and improved equipment performance and durability for the occupant. Today’s tighter homes also require proper fresh air ventilation, we use ASHRAE standards to calculate sufficient fresh air CFM and provide some different options for ways to achieve it.

2. Then, before drywall, we perform a Thermal Bypass Checklist inspection as required for ENERGY STAR certification to verify a higher standard for wall, floor and ceiling insulation that helps to assure the comfort, energy savings and higher performance of an ENERGY STAR home. We also can support your crews with training to achieve your performance goals.

3. Finally, we use a blower door, duct blaster, other diagnostic equipment and REM/Rate software to verify the finished building’s performance and submit the rating for certification. High performance ENERGY STAR homes are more comfortable, healthy and affordable for homeowners. Quite simply, an investment that pays cash returns and environmental 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!

  • 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.

  • No evidence of moisture (frost on the wall and floor)...furnace runs 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!
