Traditional in form and modern in execution, this 4,000 square foot net zero home is located on the ocean in Portsmouth, New Hampshire. The home is designed to be energy-efficient and sustainable. Roof-top solar panels generate electricity to power the home and a geothermal heating and cooling system that uses the ground as a heat source in the winter and a heat sink in the summer provide efficient and comfortable climate control.
The home is sited to maximize passive solar gain and minimize energy use. Large south-facing windows capture views of the ocean and let in the sun's rays in the winter, while smaller north-facing windows reduce heat loss in the winter. An efficient layout minimizes the exterior envelope and reduces energy usage. With its double stud exterior wall assembly, this home is expertly insulated to retain warmth during the winter and coolness during the summer.
The home's exterior siding showcases a harmonious blend of traditional and modern sustainable materials. Employing the ancient Japanese technique of Shou Sugi Ban, the wood is charred to enhance its durability and resistance to rot. This traditional element is paired with a contemporary siding crafted from recycled fly ash, a by-product of concrete manufacturing. By combining these elements, this net zero home not only exemplifies sustainable living but also serves as a testament to our ability to design inspiring, comfortable, and environmentally friendly homes.
