Kingston Springs, TN
South of Kingston Springs, TN, we are building an off-grid custom home to Passive House standards in the Mountain Modern style. At over 2300 square feet, this home features an enormous mud room, home office, screened porch, solarium, and an upstairs master bedroom with beautiful views of the surrounding woods and valley. Designed for aging in place, the downstairs master is ready to care for the owners whenever they feel the need. A beautiful two-sided wood stove will separate the dining area from the living room.
Chattanooga, TN
Located in North Chattanooga, this three story, 2500sf Craftsman style home will be the first certified passive house in Tennessee built to the Passive House Institute of the U.S. (PHIUS) standards. With 4 bedrooms and 3 baths, this home utilizes a double stud wall envelope assembly, full exterior and interior Rockwool insulation and triple pane Schuco windows and doors. Built to the highest standards in the country for air tightness, it will utilize all heat pump HVAC technology, whole house dehumdifier, and Zehnder ERV.
Hendersonville, TN
Terra Southeast has recently completed a cutting-edge passive house in Hendersonville, TN, showcasing our commitment to sustainable and energy-efficient construction. This home exemplifies best building practices, achieving an exceptional air tightness of just 0.4 ACH50. We wrapped the home in Zip-R sheathing, providing a continuous layer of exterior insulation to minimize thermal bridging. Additional insulation was added above the roof sheathing to boost the R-value and maintain a comfortable, conditioned attic space. Rockwool insulation was used to insulate the walls throughout the home.
Designed for optimal comfort and health, the home incorporates a Zehnder ERV (Energy Recovery Ventilator) to provide continuous fresh, filtered air while minimizing energy loss. Two highly efficient 1-ton mini-split systems ensure consistent temperature control throughout the year, further contributing to the home’s overall energy performance and reduced carbon footprint. Notably, this level of performance was achieved without the use of spray foam. Finally, we installed high-performance, triple-pane windows from US manufacturer Alpen Windows in Colorado, further enhancing the home’s energy efficiency and comfort.
