South Lake Union Energy District Implements Sewer Heat Recovery System

Introduction

As part of its commitment to sustainability, Alexandria Real Estate Equities, Inc. has partnered with King County to implement a large-scale wastewater heat recovery system in the South Lake Union Energy District. This innovative system will provide an alternative energy source for heating and cooling buildings, while reducing carbon emissions and improving building resiliency and operating performance.

Background

The sewer heat recovery system is manufactured by SHARC Energy and is capable of both heating and cooling purposes. By utilizing King County’s sewer system heat, the system is expected to reduce carbon emissions by 99 percent compared to a typical laboratory building in Seattle. Recognizing the potential benefits of sewer heat recovery, the King County Council authorized a pilot program, and Alexandria Real Estate Equities, Inc. is the first project to move forward with installation. Two spots in the pilot program remain open for other commercial users.

Installation Milestone

This summer, crews from McKinstry successfully cut and connected the County’s original 100-year-old brick-lined main sewer line to Alexandria’s system, proving that such a system can be installed in a dense, urban landscape. Sewer heat recovery systems are already in use in other countries like Canada, Germany, and Japan, offering an affordable and renewable energy alternative for heating and cooling buildings.

Sustainable Development Goals

  1. Goal 7: Affordable and Clean Energy – The sewer heat recovery system provides an alternative energy source, reducing carbon emissions and promoting clean energy.
  2. Goal 9: Industry, Innovation, and Infrastructure – The installation of the system demonstrates innovative approaches to decarbonizing laboratory buildings and improving building resiliency and operating performance.
  3. Goal 11: Sustainable Cities and Communities – By implementing sewer heat recovery, the South Lake Union Energy District contributes to creating more energy-efficient and sustainable built environments.
  4. Goal 13: Climate Action – The system helps to cut greenhouse gas emissions, supporting climate action goals and targets at the federal, state, and county level.

Benefits for Commercial Users

  • Reduced energy costs
  • Contributions to green building certification
  • Financing supports, such as King County’s C-PACER Program, to help developers meet stringent energy codes
  • Significant reductions in potable water use
  • Potential eligibility for state renewable energy credits in the future

Quotes

“By fostering advanced technologies that provide reliable, sustainable, renewable energy sources for heating and cooling, King County is making it easier for commercial buildings to go green. Applying proven Sewer Heat Recovery technology is the latest progress we’ve made to re-engineer our region’s built environment, making the places where we live, work, and gather more energy efficient to cut greenhouse gas emissions.” – King County representative

“Sewer heat recovery is a creative approach to reach our climate goals, and I am very pleased to see that it will be coming to South Lake Union. It will take innovative and cross-sector partnerships for our region to develop sustainably, create eco-friendly jobs, and save energy, and I believe this is an excellent first step.” – Local official

“As the preeminent owner, operator, and developer of collaborative life science mega campuses, Alexandria has long been a leader in sustainability. Our South Lake Union Energy District demonstrates our innovative approach to decarbonizing our laboratory buildings. This large-scale wastewater heat recovery system will provide an alternative energy source to heat our buildings and will improve building resiliency and operating performance.” – Eleni Reed, Alexandria Real Estate Equities, Inc.

“The partnership between King County and Alexandria portrays a framework that can be used nationwide for electrifying and decarbonizing a building’s heating and cooling loads, while reducing energy costs, saving freshwater usage in cooling towers, creating ‘green’ economy jobs, and helping achieve climate action goals and targets at the federal, state, and county level.” – Partnership representative

“McKinstry is proud to be a trusted design-build partner working to deliver on Alexandria’s vision for the project, including bringing to fruition the heating and cooling system that’s putting this project on the map as one of the largest sewer heat recovery systems in North America. The new campus creates more than 5,200 construction jobs for our local economy and bolsters the Puget Sound region’s green economy.” – McKinstry representative
