Alexandria Center for Life Science

Public+private partnership accelerating net zero

King County and Alexandria Real Estate Equities, Inc. (ARE) are pioneering a ground-breaking project that captures heat from a large, underground sewer pipe to warm a 1.6 million-square-foot life science mega campus in Seattle’s South Lake Union neighborhood.

A first in the realm of large commercial projects, this initiative showcases how public-private collaborations can contribute significantly to reducing greenhouse gas emissions.

Highlights:

  • 99% carbon reduction (as compared to traditional lab)
  • 70% of campus building heat provided from city sewer wastewater
  • leverages King County’s groundbreaking public-private legislation

Project Overview

The Alexandria Center for Life Science, a landmark 1.6 million-square-foot life science mega campus in Seattle’s South Lake Union, represents a cutting-edge example of sustainable urban development. 

Using advanced heating and cooling wastewater energy technology (SHARC Series) the system consistently extracts heat from a county sewer pipe, processes it through a heat pump system, and then distributes it across the campus. 

This technology is not only a first in the nation for its scale but also a game-changer in terms of environmental impact. It is projected to reduce carbon emissions by a staggering 99% compared to conventional energy sources used in similar buildings in Seattle. 

The system’s implementation is slated for 2025, marking a significant step towards sustainable urban living.

King County’s involvement highlights its commitment to innovative energy-saving solutions and reducing greenhouse gas emissions. The county’s initiative to develop commercial interest in sewer heat recovery is part of a broader strategy to encourage sustainable practices in commercial and multi-family buildings, which account for a significant portion of countywide emissions. King County’s pilot program for wastewater energy underlines its proactive stance in promoting renewable energy sources and partnering with the private sector for environmental stewardship.
