First Climate-neutral certified Passive House Plus in Minneapolis.
Modern ultra-sustainable design. 

The ‘Good Energy Haus’ is a truly carbon-neutral, urban certified Passive House Plus in Minneapolis, Minnesota. Designed by Tim Delhey Eian, principal of TE Studio, the home was built in 2019-20 by Tanner Construction and serves as a beacon for sustainability, as well as a demonstration showcase for the design firm and its partners.

‘Good Energy Haus’ is a case study for modern, sustainable urban living. It is a Certified Passive House Plus in US Climate Zone 6, and an insulated wood-frame construction with upcycled dense-pack cellulose insulation. It is powered by a photovoltaic system with 100% wind-electricity backup.

Realization

If you had to do it again?

Slab on grade concrete pour was too uneven for polishing. Ended up having to pour self leveler and install cork flooring. Would use a specialized concrete contractor in future and/or set slab at lower elevation and utilize self-leveling overpour as standard. Open living area sound is lively. Would utilize more sound-absorbing materials in future.

Building users opinion

Comfort is tremendous on sunny, cold days. Like a higher set point on cloudy, cold days. Air quality is stellar (is monitored 24/7). Illumination is wonderful (lots of daylight = need very little artificial light).
