Climate Pledge Arena
780,744 sf | Seattle, Washington | Critical Environments
Located at the base of the iconic Seattle Space Needle, Climate Pledge Arena takes the lead as the most progressive, responsible, and sustainable arena in the world.
Hermanson completed HVAC and Plumbing construction scopes for this extraordinary project. Working hand-in-hand with the GC, designers, and the full project team, Hermanson assisted in addressing the many challenges associated with the complete reconstruction of the arena, with only the roof remaining of the original, tripling the square footage of the previous space and providing a modern sports and entertainment arena that seats up to 18,100. Hermanson’s services were critical to meeting the project’s sustainability goals:
Carbon Zero: Climate Pledge Arena is the world’s first International Living Future Institute-certified zero carbon arena! The arena consumes no fossil fuel to run daily activities, runs off 100% renewable power from on and off-site solar panels, and purchases carbon offsets.
Water Conservation: The “Rain to Rink” system harvests water off the roof, collects it into a 15,000-gallon cistern, and turns it into the greenest ice in the NHL. The arena also hosts waterless urinals, ultra-efficient showers, & water bottle refilling stations.
Unique Challenges: Construction began on this amazing project in late 2019 and was getting rolling when the COVID shutdowns of 2020 hit. Our management team and crews quickly adjusted to evolving safety standards and, in a short time, were back on site, working to meet the strict project schedule.
