In 2011, Eagle Bluff Environmental Learning Center completed a Deep Energy Reduction Retrofit of its director’s residence—its oldest most energy inefficient building—with the help of TE Studio. The residence was originally built in 1973. It used to be heated with 17 cords of split, dried oak firewood. It was extremely leaky—during a home audit in 2007, it would not achieve 50 Pascals of pressure during the initial blower door test. It eventually achieved a 0.45 ACH50 reading.
We provided initial consulting and retrofit designs for this project, which was later executed with the help of many volunteers. The home was just recognized by ACI as the 9th in the country to meet the 1000 Home Challenge, and as the first project in Minnesota to do so.

We finally got around to rendering a current project in rural Minnesota. This farmhouse replaces a family home and becomes the new hub on the property. It is designed to meet the Passive House standard and become net-zero or energy plus with the addition of a future PV system on the south-facing roof slope, as shown on the southwest corner rendering below.
In addition to the living spaces, this project includes a front porch, garage/workshop, and back porch.
Ground breaking is scheduled for late summer.
One of our early works was just awarded the Minnesota GreenStar Gold certification—representing their highest category for remodeled homes. The project consisted of building envelope upgrades and mechanical systems enhancements, as well as remodeling and adding with earth friendly practices and materials.
The Passive House in the Woods received the highest Minnesota GreenStar® certification (Gold) today. We are very excited to see the certification come through and congratulate the owner and all the team members involved in the design and construction on this achievement!
We used the Minnesota GreenStar® program to compliment the Passive House certification. It’s green markers helped track resource efficiency, indoor environmental quality, water conservation, and reduced site and community impact, with the energy efficiency requirement being met and exceeded by the achievement of the Passive House certification.
Tim Delhey Eian will be lecturing on holistic design and the Passive House building energy standard on May 1, 2012 at 2.30 in room 31 in the basement of the old wing of the architecture building.
Want to learn about Passive House retrofitting? Tim Delhey Eian will be showcasing a recent Passive House retrofit project in the TwinCites—the MinnePHit house in a presentation on Saturday, May 5, at 2pm in Bay A at the 4-H Building; MN State Fair.
Thinking about building or remodeling a home, or want to know more about energy efficient technology to reduce your carbon footprint as well as your heating and cooling bills? Tim Eian has focused his architectural skills on incorporating the latest technology in energy efficient new and remodeled homes, which use a tiny fraction of most houses.
This presentation at the North Hennepin Community College highlights the “MinnePHit House” project in South Minneapolis—a deep energy reduction project that turns a 1935 house into a Passive House home.
Time: 10 – 11 AM
Location: North Hennepin Community College CLA 133
