To find out more about our project, here's a documentary about our house and other projects.

Instead of tearing down our 100 year old Ballard home and rebuilding it with a 'green' built house, I decided to save what we had and turn it into a low consumption remodel that actually makes us money through power generation. Soon, our year round water needs will be supplied predominately by rain water.

Our rain catchment system collects 3400 gallons of water, and overflows to our rain garden that utilizes native and edible plants. We'll also have examples of Rotoplast and Premier slimline cisterns on site for you to compare.

The yard is grass-lawn free and we continually add more edibles to complement our 1000 square feet of vegetable gardens.

The house remodel was done using around 75% reused/recycled materials and lumber milled from windfall trees from our Hood Canal property. Additionally, we used materials from old bridges, train tunnels, buildings, etc..

We have over 15 types of LED lighting throughout the house along with efficient appliance. These efficiencies bring our usage down to 12 KWH per day (6.85 with the solar) vs. the US average of 35KWH per day.

Our 3800 watt solar PV array produces 60% of our annual electricity for our home and electric car. Our electric bill averages $200 per year and we receive $380 per year from the Seattle City Light production incentive program.

The house has been super insulated with an exterior encapsulation of rigid foam.

The kitchen cabinets and Sub Zero refrigerator came from a home in Madison Park, and were purchased at The Re-Store for $3000. The cost of these new would have been around $35,000 combined, and were in near perfect working order when I bought them.

Rain gardens in your urban or suburban yards and landscapes help rainwater to naturally percolate into the ground. This project features rain gardens and a full array of other sustainable building features as well. Lots to see at this Tour Site Stop.
