The Mount Vernon Library Commons project in Washington State is positioning itself as one of the region’s most environmentally conscious publicly funded developments.
With a budget of US $53 million, the 133,000 sq. ft multi-functional project encompasses a public library, community center, and structured parking, serving the City of Mount Vernon which is just an hour north of Seattle. Notably, it is also the first publicly bid Passive House project in the Pacific Northwest.
Taking the lead on this ambitious venture is the local design team at HKP Architects, which set out with a primary objective of reducing the concrete’s carbon footprint by 30-35%, with an aspirational stretch goal of surpassing this target. Through close collaboration with KPFF Engineers and local concrete suppliers, the project has now exceeded expectations, anticipating a remarkable 40% reduction in concrete’s global warming potential (GWP) through an innovative approach to mix design.
To achieve such remarkable results, HKP Architects worked closely with the City of Mount Vernon, sustainability consultants, and structural engineers. Together, they carefully assessed the risk and return associated with pushing the boundaries in sustainable construction, making informed decisions based on scientific analysis.
By surpassing concrete GWP reduction goals, the Mount Vernon Library Commons project demonstrates its unwavering commitment to sustainability. As the construction progresses, it continues to serve as a beacon of hope, showcasing how public projects can lead the way in creating a greener future.
