Home Progress 8: January to April 2012

Happy New Year!
We moved into our side of the duplex over Christmas.  Nice holiday present and what a wonderful way to start the new year!  Thank you PDX Living and all of your helpers for building this unique and beautiful home for us!

The other side of the duplex is nearing completion...


Come on in...

Up the stairs to our 2nd floor living area...
Durable solid strand woven bamboo flooring
South-facing windows let in lots of natural light and contribute to passive solar heating in the winter.  In summer, the roof overhang on the south facade provides shade and keeps this space cool.

Kitchen...

2nd floor bathroom...

2nd floor bedroom...
His & Her closets

!st floor front bedroom/office...
Has sliding bamboo door

1st floor back bedroom has mirrored closet door

Bosch Axxis washer and condensation dryer.  This ventless dryer eliminates the air leakage from a conventional vented dryer.


New shed (to be painted in spring to match house)...

We've planted a street tree too- a paperbark maple.

Notice a few small changes from original design...

April 2012
TrekHaus duplex's  West unit gets 4.70 kW (20 panel) system SolarCity worked with us to design a custom racking system using Schletter rails which mount on the parapet walls of our low slope roof, maintaining the integrity of the white FiberTite roofing membrane.  The solar panels will operate more efficiently on a cool white roof compared to a more conventional dark roof.  The custom design also allows for abundant air flow underneath and around panels which further enhances efficiency.  Five solar panels mounted per rail pair with four rows.   For our particular installation on south-facing low slope roof, the panels are mounted at a 5 degree angle.  With current system, West unit is on track to be net-postive.  Will monitor awhile before installing panels on East unit.  Thank you SolarCity!  Thanks also to David Swyter (Total Home Inc.) for installing the high performance roof!
