House Facts
Structural Facts
- The structure is positioned facing due south for maximum solar exposure.
- The solar array in the house was designed to provide electricity for the house year-round during peak daytime demand.
- Helical Pier Foundation System minimizes disturbance of native soils. Twenty-three screw-in posts were used for the foundation. This system is also removable, reusable and performs well in expansive soils. It does not restrict drainage of surface water.
- Butterfly Roof allows for maximum capture for rain water and negates the need for gutters.
- Casement windows allow home to cross ventilate and capture prevailing winds
- Open-joint Rain Screen allows ventilation in exterior walls which improves indoor air quality.
- Single interior plumbing wall contains all plumbing to minimize distance of piping runs. Locating plumbing in an interior wall allows for more insulation in exterior thermal envelope.
- SIP (Structural Insulated Panels) Construction used to build floor, walls, and roof systems: Minimizes waste, highly insulated and durable, reduces construction time. The pre-fabricated panels were delivered on one truck stacked like a deck of cards.
- Daikin- 4 zone Ductless mini split HVAC system provides cooling and heating: Improved efficiency with no duct leakage, reduce size of equipment and materials necessary.
- No East or West Facing windows or glazing.
- Project was designed in 2’ foot increments to minimize onsite construction related waste.
- Dual purpose Southern Solar Porch covering: provides shade for 12 foot door system during summer and renewable energy production.
- Retractable Door: allows for increased space and ventilation. Large Southern facing doors/ windows provide passive solar heating during winter months and large amount of natural light to reduce need for task lighting during daytime hours.
