Thermal Envelope Structure and Insulation :
Active Solar :
- Domestic water heating
- 3.4 Kw Photovoltaic array grid tied with excess electricity purchased by Tucson Electric Power resulting in near net zero energy use
Passive Solar :
- North/south solar orientation - no major east or west facing windows
- Large covered porch, trellised or tree shaded south facing windows
- Direct solar gain minimized to prevent interfering with radiant floor
Heating/Cooling and Ventilation :
Hydronic radiant floor cooling & heating system with thermal mass of the entire finished concrete floor utilized as thermal storage & delivery medium providing & maintaining consistent indoor air temperatures without need of forced air movement that by its nature creates hot & cold drafts. A properly sized forced air system provides backup heating, cooling & dehumidification, IF needed. A separate whole house fresh air exchange ventilation system operates intermittently 24/7.
