Positioned on the corner of S Alaska St. and Martin Luther King Jr. Way S near the Columbia City light rail station, this new 91-unit transit-oriented development is certified both Built Green 4-Star and National Green Building Standard (NGBS) Bronze level. Committed to building green, BDR Holdings’ Sonata building obtained 535 points on the multifamily checklist—135 points over the required 400 points for 4-Star.
Some of the Built Green credits that aided them in achieving their high score were using low-toxicity, low-VOC products, no added urea formaldehyde (NAUF) millwork and cabinets, and CRI Green Label Plus carpets throughout the building. Part of their energy savings comes from the centralized high-efficiency gas water heater, the extra roof insulation above the sheathing, and the rooftop PV array. Outside of the building, all landscaping is drought-tolerant, surfaces are pervious to allow for water infiltration, and nontoxic outdoor materials were used to finish off landscaping.
