SEA Airport - C Concourse Expansion – Sustainability Aspects
This project aligns with the Port of Seattle’s ambitious environmental goals, aiming to become the greenest and most energy-efficient Port in North America. Environmental health and the well-being of travellers are central to this endeavour.
This project marks the first at SEA Airport to integrate the Port’s Sustainable Evaluation Framework. The facility’s roof will incorporate a solar photovoltaic array, harnessing the sun’s power for sustainable energy.
Moreover, the design incorporates materials with reduced embodied carbon and healthy components, contributing to a greener, healthier environment.
To create a stronger connection between guests and the natural world, biophilic design elements are being integrated. The indoor environment will also feature a high-performance air delivery system, enhancing indoor air quality.
Bill Ketcham, Vice President and General Manager of Turner Construction Company, highlighted the significance of this project. He emphasized the positive impact that sustainable building strategies can have on the terminal’s expansion, reflecting a strong commitment to environmental responsibility
