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.

Owner approach of sustainability

Maximize efficiency with the help of Passive House. Fuel responsibly with wind and solar energy. Use people and earth friendly products throughout. 

Architectural description

The Good Energy Haus is a detached single family home on an urban infill lot in Minneapolis, MN. It offers 4 bedrooms and 3 bathrooms on two floors. A basement was omitted to save on space and cost. The attached garage serves as overflow space for storage and hobbies. It is ventilated and conditioned. 

The house is oriented perfectly south to maximize passive and active solar heat gains. The rear of the home opens up to engage with the backyard, offering views, light and the enjoyment of the outside in a climate zone with a long winter.

The first floor is accessisble with a bath and bedroom for aging in place. All entrances are zero-step. 

The second floor holds a master suite and two bedrooms with one bath, as well as the laundry room. 

 

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).
