Special features

  • The Ocean Pavilion is targeting Living Building certification in critical performance areas, with a focus on planet-positive energy use.
  • The Pavilion will be 100% fossil fuel-free and has a goal of net-zero embodied carbon.
  • The Ocean Pavilion will have a 70% energy use reduction and 95% carbon emissions reduction compared to similar aquariums.
  • Innovative use of a central air heat pump system, a semi-closed water system, LED lighting, low carbon building materials, and high-performance glazing will reduce energy and water consumption and carbon footprint. In addition, the planted roof surfaces will reduce pollution from stormwater.
  • Water-to-water heat exchangers will recapture heat from tank water being discharged and use it to heat the incoming makeup seawater from Puget Sound. Using water from Puget Sound reduces the amount of potable water used for exhibits.
  • The energy recovery system uses air-source heat pumps that recover and move heat very efficiently from the chilled and heating hot water loops.
