The ECO2 House
Greentech and F5 Design/Architecture are currently designing a small high-performance eco-house for construction on Poplar Court at the very special Evans Farm (1) New Urbanism community in Lewis Center. It will be a ranch style structure where everything needed for daily living will be on the main floor, all-electric (no fossil fuels), solar, and utilize highly efficient HVAC and appliances.
We think about this project as ECO2 because it will create an efficient home AND an affordable home, that is, ECOlogically sound and ECOnomically sound. We think this is important to build all homes to this standard as we move into a challenging environmental near-future where we will all have to do much more to reduce global warming and energy consumption.
Interested? Call us to discuss the project.
Work at the Legacy House is just finishing up. Its owners wanted to create a home that would be practical in a changed environment, where reduced energy consumption and fossil fuel carbon emissions are of very great importance.
The Department of Energy certified Zero Energy Ready all-electric Legacy House at Evans Farm in Lewis Center, Ohio had a June 2019 AEP electric bill of $9.50, thanks to its 7.2kW solar panel array and a super-tight SIP envelope.

New Albany House
We saved an existing small ranch home and greatly expanded it by adding a much larger structure on a Superior Wall basement, including an 1880’s timber frame.

Delaware Farm House
An historic timber frame built in 1862 that was once a home on Havens Corner Road in Gahanna, Ohio was dissasembled and moved to southern Delaware County where it was incorporated into a new farmhouse styled house. It now is the sunroom, kitchen and great room of this home.
Top of the Hill House
Sitting atop one of Ohio’s “mountains” offers this home a commanding view.
It also presents us with a challenge. Taking advantage of the beautiful northern vista through a wall of glass requires special heating and cooling load considerations. A SIPS house with 8″ wall and 12″ roof panels, triple pane windows and a geothermal HVAC system helps us create a tight efficient Building Envelope.
It all starts with the installation of the pre-cast Superior Wall basement system shown in the video below. They come in 8, 9, 10, or 12′ wall heights.
SIPS walls and roof panels have been installed on the Superior Walls basement and 100 year metal roof is being installed.
This is one our best examples of a High Performance Home. Its recently completed blower door test yielded a score of .59 Air Changes per Hour @ 50 Pascals which places the house in the Passive House Institute US standard.
