A tour of the 2015 LEED Homes Project of the Year
Developed by SolTerra and designed by Abbasi Design Works, the LEED Platinum, 18-unit, mixed use building used design and construction strategies aimed at reconnecting residents with nature while pulling double duty for water and energy efficiency.

The Woodlawn uses 53 percent less energy and 57 percent less water compared to a typical low-rise apartment building. In its first year of occupancy, it saved nearly 100,000 kWH of energy.
How’d it do that? The project team cites high-efficiency, heat-pump water heaters; heat-pump mini-splits for space heating and cooling; double-pane low-e windows; R-31 exterior walls; Energy Star appliances; LED lighting; and low-flow plumbing fixtures, which reduce hot water demand.

Taking a cue from nature
Among the highlight reel of The Woodlawn is its 4,500-foot ecoroof with drought-tolerant vegetation, an outdoor terrace and more than 1,100 square feet of living wall siding, the largest display on a single building in the Northwest.
The building also has seen heavy cuts to its outdoor potable water use for landscaping, thanks to a powerful irrigation system and a 9,000-gallon rainwater cistern. Two bioswales soak up the remaining stormwater to completely eliminate runoff into the streets and storm sewers, qualifying the project for Portland’s Clean River Rewards program.
