Foundation Drain

This picture shows placement of drain rock over perforated pipe for drainage of excess ground water around the foundation of the custom home on columbia street. We are using Gradeline aggregate to place the rock. Next we will place filter fabric on top of the drain rock and backfill to grade with clean dirt.

Columbia St. Green Home

Energy trusses are now installed and roof framing is progressing. Note the asymmetric roof lines designed to accommodate solar equipment on the south facing roof. Three foot overhangs help to shade summer sun from southern exposure windows. Lower sun angles in the winter will provide exceptional solar heat gain when it is most needed. Radiant concrete slab in the living space provides thermal mass to store heat and assist the gas fired boiler.

Columbia St. High Performance Home

This is our current green building project at 824 NW Columbia St. in Bend, Oregon. The home incorporates 2x8 staggered stud advanced framing with all FSC certified kiln dried lumber. This type of construction produces better R-values than typical stud framing at a reasonable cost. The home is now ready for raised heel energy trusses, which also help with insulation by reducing compression of roof insulation at the exterior wall.
The Columbia St. home will incorporate blown-in cellulose insulation, solar hot water, solar space heating, and solar electric. In addition, home design and site orientation were designed to optimize passive solar. This helps to keep the home cool in the summer and warm in the winter. The home will be certified through Earth Advantage and the High Performance Home program through the Oregon Department of Energy.
Keep checking back for more updates as construction progresses.
