Located on the south side of Spencer Butte in Eugene, Oregon the residence showcases sustainable design, state-of-the-art technology, and thoughtful material selection. The design optimizes daylighting using high-performance windows and doors to frame the views of the surrounding landscape. The performance of the building envelope is also emphasized using advanced insulation techniques, an airtight wall assembly, and an exterior rainscreen to maximize protection against the elements and achieve insulation values far beyond code. Heating and cooling of the house relies on a geo-source heat-pump. Combining a highly-efficient HRV system with radiant floor heating, the homeowners are able to control seven distinct thermal zones. When not occupied, the zones use the latest in sensor and automated home technology to keep the home comfortable while minimizing energy consumption. The house also features the latest in renewable energy. Photovoltaic panels provide back-up energy for the residence and a charging station for an electric car, while solar hot water panels meet demand for domestic hot water. A vertical wind turbine, prominent at the site’s entry, contributes to the production of energy at the residence. Water conservation is also emphasized at the residence. EPA Water Sense plumbing fixtures are used throughout the house, while the landscape was designed for water efficiency. Drought-tolerant native plants line the landscape, cared for with site-specific drip irrigation zones.
