Question: In which county is the town in which the BrightBuilt Barn project was first established ?
Context: John McGreer Barn and Crib are historic structures located in rural Harrison Township, Lee County, Iowa, United States.  They are located on a farm northwest of the town of Donnellson.  The agricultural buildings were listed on the National Register of Historic Places in 2001.  The barn was built in 1884 in the Pennsylvania barn style.  It measures 76 by , and features a cupola on top.  The corn crib is located west of the barn.  The 32 by structure was built around the same time as the barn.  It has a round arch window in its gable front.  The barn and corn crib were two of 13 extant buildings at the time of their nomination on the former John and Julia McGreer farmstead. The William Dyas Barn is a historic agricultural building located south of Bellevue, Iowa, United States.  It is one of over 217 limestone structures in Jackson County from the mid-19th century, of which 58 are non-residential, agricultural related structures.  The stones used to build the barn were quarried, but they vary widely in size and shape.  The larger stones are at the bottom of the structure, and they diminish in size the higher up on the walls.  An unusual feature on this barn is that the gable ends are not stone, but timber.  The Dyas family were among the first settlers in Jackson County, arriving in 1833.  They built five houses in this valley.  William Dyas built a brick house along with this barn.  It is believed there were many more stone barns in the county, but they have been removed over the years.  That gives this barn the added significance of being an example of a vanishing building type.  It was listed on the National Register of Historic Places in 1991. The Barn on Lot 8, Range G is a historic barn in rural Franklin County, Maine.  The barn was built in two stages, the first estimated to be around 1825, the second in 1899.

The Howe Barn is a historic barn, that has been converted into a house, in Ipswich, Massachusetts, United States, at 421 Linebrook Road (403 before the street was renumbered).  It is important as one of a small number of surviving First Period barn frames in Essex County.  Family tradition places the construction of the barn to c. 1711 by Abraham Howe, an early settler of the Linebrook Road area.  Elements of the frame, which are still visible in the attic and some areas left exposed during the 1948 conversion to a house, bear some resemblance to a similar period barn at the Stanley Lake House in nearby Topsfield. George R. Cogar (born 1932) was the head of the UNIVAC 1004 electronic design team code named the "bumblebee project", and later the "barn project", and co-founder of Mohawk Data Sciences Corporation, a Herkimer, N. Y.-based multimillion-dollar business built largely on his invention of the Data Recorder magnetic tape encoder, which was introduced in 1965 and eliminated the need for keypunches and punched cards by direct encoding on tape.  He also founded the Cogar Corporation, where he built an intelligent terminal—an early forerunner of the modern personal computer—which he called the Cogar System 4 or Cogar 4.  The Cogar 4 became the Singer 1500 after Singer Business Machines acquired Cogar Corporation.  In 1976 International Computers Limited (ICL) acquired Singer Business Machines, changing the name of the computer to the ICL 1500. WPA Stock Barn and Pavilion, also known as the Rock Barn, is a historic barn and pavilion located at Trenton, Grundy County, Missouri.  It was built in 1938 as a Works Progress Administration project.  It consists of a two-story, octagonal barn with attached one-story stock pens.  The building is constructed of native stone on a concrete foundation.  The building served as a livestock housing and sales pavilion for the annual Grundy County agricultural fair. Rockport is a town in Knox County, Maine, United States.  It is thirty-five miles southeast of Augusta.  The population was 3,330 at the 2010 census.  Rockport is a popular tourist destination and art colony. Ramsay–Fox Round Barn and Farm is a historic round barn and farm located in West Township, Marshall County, Indiana.  The farmstead was established about 1900.  The round barn was built about 1911, and is a true-circular barn, with a 60-foot diameter.  It has a two-pitch gambrel roof topped by a cupola and consists of a main level and basement.  Also contributing are the farm site, farmhouse (c. 1900), milk house (c. 1900), windmill (c. 1920), and privy (c. 1900). The Michael Klunk Farmstead is a historic farm located on Crater Creek Road south of Kampsville in Calhoun County, Illinois.  The farm consists of a well-preserved house and barn.  Michael Klunk, an immigrant from Alsace-Lorraine, established the farm and built the barn in 1830; the north crib of the barn served as a farmhouse until the present house was completed in 1875.  The barn is a log double crib barn, while the house has a central hall plan; both designs were common vernacular building types in central and southern Illinois. A BrightBuilt Barn, is an eco-friendly project that is directed towards creating a more sustainable building.  It was first established in Rockport, Maine by Kaplan Thompson Architects and company, when a rich entrepreneur contacted them by the name of Keith Collin.  The BrightBuilt Barn is the creator's sample of what a more sustainable building can look like, for people to possibly live in.  The idealist Keith Collin and company wanted a sustainable, low cost, and environmentally friendly home.  At least that was the Collin's plan,since 2006.  So far there are only prototype BrightBuilt houses produced.  Collin wants the beginning design to be a pathway towards implying more technological applications into common day houses, to bring better result for the environment, or at least that is his vision.  From its inception, the design was driven by five guiding principles: livability, sustainability, replicability, disentanglement, and education.  In the eyes of the designers this barn project is a stepping stone toward the future improvements that can start right now, especially since the barns Net Zero design can benefit the environments situation.  The benefit could mean more energy is conserved in the years to come, which can help other small towns like Collin's.
