Krista Atkins Nutter, designer and owner of the Nutter Green Home, is a
certified interior designer with an MS Architecture degree and is a
Professor of Design. She and her husband, Kenneth have built a
super-insulated, energy-efficient, passive-solar, solar-electric home
with solar hot water heating and a rainwater catchment system to provide
water for toilet-flushing, clothes-washing, and outdoor uses. The home
is designed for the local climate, and has achieved an Energy Star
Rating of 5+ Stars, a 2007 Cincinnati Sustainability Award and a 2008
Excellence in Design Award Runner-Up selection in Environmental Design +
Construction Magazine. One of the main goals of the home is to serve as
an educational model for the community. The Nutters have given seminars
on the Nutter Green Home to various groups, including students of all
ages, the US EPA, the NeoCon World's Trade Fair in Chicago, and Green
The site for the project is a sub-urban infill lot with surrounding
homes 25 years of age. The site was selected for its unobstructed
southern exposure and close proximity to services such as retail,
churches, healthcare, schools, ect. The home is a 2,300-square-foot
modern-industrial, environmentally-sensitive dwelling utilizing
strategies such as an insulated concrete form foundation, spray foam
insulation, value engineered framing, suspended concrete floors,
environmentally-sensitive materials such as recycled glass counter tops
and bamboo stair treads, water-conserving low flow faucets and dual
flush toilets, two high-efficiency heat pumps for back up heating and
cooling, a heat recovery ventilator to supply the home with fresh air,
and a 4.4 kW photovoltaic roof-mounted array. The exterior of the home
features recycleable Galvalume and fiber composite siding. All concrete
used in the project utilized 20% fly-ash.
The home with its grid-tied solar PV system, installed in March 2007,
recorded its first positive electric bill in Aug./Sept. 2007 (which was
quite a hot month in Cincinnati where temperatures consistently reached
the 90s Fahrenheit). With both heat pump condensing units running and
the thermostats set to 74-degrees, the electric bill from mid-August to
mid-September was $8. All bills prior to that were credits ranging from
$40 to $60.
Superior indoor air quality is achieved through zero-voc finishes, low
or no-formaldehyde construction products, a high-efficiency electronic
air filtration system, a heat recovery ventilation system, and by
sealing all metal ductwork with mastic.
The home was built for $100 a square foot, excluding the cost of the
solar PV system. A grant from the Ohio Department of Development was
awarded to the owners to help offset the cost of the PV and solar hot
water heating systems.
The home also features native landscaping including a rain garden, a
constructed wetland, a native prairie, a vegetable garden, and other
plants native to southwestern Ohio. Like the home, the gardens will be
open to the public for tours and seminars which discuss the importance
of native landscapes, habitat preservation, and stormwater runoff
retention. The National Wildlife Federation has designated the property
as a "Certified Backyard Wildlife Habitat."
