Living Off the Grid: A Case Study in Energy Independence and Resilience

The Hinshaw-Latham Residence is a 1,636-square-foot energy-efficient home situated beside a bird sanctuary in Tontitown, Arkansas. Thoughtful orientation and site planning allowed the design to work in harmony with the landscape while maximizing the benefits of passive solar strategies. Developed in alignment with the homeowners’ vision, this off-grid home virtually eliminates reliance on fossil fuels and significantly reduces its carbon footprint.

The project began with the construction of a farm workshop, followed by the installation of a 6 kW solar system paired with a two-stack HomeGrid battery (4.8 kWh x 2 = 9.6 kWh). This home demonstrates true off-grid potential—not through an oversized solar array, but through a carefully integrated design-build process rooted in building science. It begins with a high-performance building envelope featuring an ICF foundation, insulated OSB sheathing, energy heel trusses, an Ice House Roof system, and spray foam insulation. These elements work together to drastically reduce energy demand, making a smaller solar system not only feasible but highly effective.
