STACK HOUSE APARTMENTS VERIFICATION
They also provided in-field training and feedback on implementation using both visual verification and performance testing to build the construction team’s capacity and ensure a successful certification outcome.A threaded rod with a clevis assembled on each end is known as a tie-rod assembly, and Portland Bolt manufactures thousands of these assemblies each year for a wide range of projects. The threaded rods and clevises are often used as bracing in wood or steel buildings and can often be found attached to steel columns or trusses in large buildings. Given the high performance expectations, the O’Brien360 field team worked closely with the general contractor, Exxel Pacific, and their sub-contractors to ensure the construction details necessary to achieve the performance requirements were clearly understood. In addition to early design facilitation, O’Brien360 also acted as the LEED for Homes Provider and Green Rater, offering quality assurance and verification oversight of the design and construction process. In addition to these performance goals, the design team, led by Runberg Architecture Group, focused on maximizing amenities for tenants in this dense urban area, including view corridors to Seattle landmarks and accessible green spaces, such as an indoor, unconditioned “wintergarden” that offers sheltered access to green space even in the cold and damp of winter. of commercial space and is also pursuing LEED Platinum.ĭeveloper Vulcan Real Estate commissioned O’Brien360 to facilitate the pre-design process for the project, during which they set ambitious performance targets including LEED Gold or Platinum certification and an Energy Use Intensity (EUI) of 28 kBtu/sqft/yr to comply with the Seattle 2030 District requirements for energy and water consumption. This exemplary use of an infill site creates a development density of 182 units per acre! The rest of the block is occupied by the Supply Laundry building, a historic landmark, which has been restored and adapted for an additional 30,000 sq.ft. The apartment complex consists of two mid-rise buildings, providing 279 apartments and roughly 9,000 sq.ft. The Stack House Apartment project is certified Platinum under the LEED ® for Homes Mid-Rise Rating System and meets the energy and water consumption requirements of the Seattle 2030 District high-performance building challenge.

Rainwater harvesting and 42,000 gallons of cistern storage provide more than 60% of irrigation demand for external landscapes, the “wintergarden” and green roof areas.
