TrekHaus is a super energy efficient duplex built by PDX Living. It is home to Ella Wong and Randy Hayslip. As solar energy and energy efficiency geeks, Ella and Randy are on a trek to reduce their carbon footprint and hopefully on the way get others to do the same. A featured home from Solar Oregon’s 2012 Goal Net Zero Home Tour, TrekHaus has a 4.70 kW photovoltaic system installed by SolarCity, and is Earth Advantage Platinum and Passive House Certified.  Amazingly, TrekHaus West has exceeded net-zero expectations and has been operating net-positive by more than a 50% margin for over 2 years now! 

Average solar energy generation: 14 kWh/day.  

Average energy consumption: 9 kWh/day.  

Overall, net positive by average of 5 kWh/day (which is enough electricity to run a Nissan Leaf about 5500 miles per year or 15 miles per day).  

The excess electricity is donated to Portland General Electric’s low-income assistance program.
