Along with everyone in the City of Portland, we are anxiously anticipating the opening of the Park Avenue West Tower – the long-awaited, elegant new high-rise that is helping transform Portland’s skyline. The project is slated to open in early 2016. Assisting the PAWT team achieve a comprehensive approach to sustainability was both fun and challenging for our in-house experts. The $180 million project stands as an environmentally and socially responsible development in the heart of downtown Portland’s central business district. GBS provided sustainability consulting for the 546,000-square-foot mixed-use space, in addition to spearheading fundamental and enhanced commissioning. As a result, it received pre-construction LEED-CS v2.0 Platinum certification. With two stories of retail, 13 stories of Class A office space, 15 floors of residential units, and six stories of underground parking, the tower’s green features include:
– An improved thermal envelope and high-performance glazing.
– A radiant heated/cooled slab in lobby that takes advantage of the concrete’s thermal mass and heat pump efficiency.
– Reclaiming 425 gallons of rooftop rainwater for toilet flushing.
– Occupancy sensors and daylight controls in the office areas, and an optimized lighting design on office and residential floors, predicted to be 40% more energy efficient than a building built to code.
– Regionally-sourced and recycled-content materials
– High-efficiency condensing gas boilers for domestic hot water that are 16% more efficient than code
– Fan-powered VAV system with ECM motors, and high-efficiency floor-by-floor VAV air handlers in office spaces
