    • Solar heating for domestic water (2 extra large tanks) and radiant floor heating
    • Individual zones for heating of almost every individual room 
    • Pool solar water heating 
    • Whole-house fans (hidden in the top of the high ceiling above the upstairs hallway) allowing faster cooling of the house during summer evenings
    • EV charger (Level 2, 32 Amp charger in the garage)
  • Construction
    • Engineered lumber framing: Timberstrand (a laminated strand Lumber made from fast-growing aspen and yellow poplar) stays straight, is free of knots and resists twisting, shrinking and bowing. It is also enormously robust and long lasting, so it will hopefully stay away from landfill for a long time
    • Sprayed-in, soy-based formaldehyde-free insulation made from a renewable resource and also benefits the general air quality in the house
    • Brazilian slate tile floors installed throughout the home are beautiful and easy to clean; this flooring also furthered the ability of the house to keep warm longer in winter and cold longer in summer, contributing to passive climate control
    • Double pane gas-filled, energy-efficient windows throughout
    • Kitchen: Formaldehyde-free, environmentally friendly Neff kitchen cabinetry and energy saving appliances (induction stove top, energy-saving low-noise dishwasher, etc.) 
  • Yards
    • Non-organic surfaces were chosen to be water-permeable – allowing water to penetrate the ground below and recharge the groundwater instead of running off to the street, collecting pollutants, then getting flushed into the bay
    • Light pavers were chosen as a result of concern for the so-called “heat island” effect in urban areas where darker surfaces can cause unnecessary heat buildup
    • Watering systems for the yard are chosen mostly for their efficient drip and micro-spray irrigation
    • Outside lighting avoids light pollution at night by pointing downward


  • Whole-house audio, built-in stereo speakers in 10 rooms and 2 outdoor spaces
