Project Overview

303 Battery will be the world's first net-zero energy high-rise apartment building. In addition to providing design and manufacturing for Sustainable Living Innovations (SLI), UMC prepared building analysis and energy models to achieve the maximum 30 LEED points as SLI pursues LEED Platinum certification.

UMC has been a part of several remarkable buildings in downtown Seattle: The Space Needle, Columbia Center, Benaroya Hall, The Spheres... And now, 303 Battery: The world’s first net-zero energy high-rise apartment building. While this building will not rise as tall as others that came before it, it is slated to revolutionize the future of buildings around the globe.

In addition to the design, manufacturing, and installation of the wall panel piping systems and central plant kits, Sustainable Living Innovations (SLI) tapped UMC to conduct a building energy analysis, modeling, and document preparation to pursue the LEED Platinum certification. To achieve the maximum LEED points (30), the energy model needed to demonstrate over 60% of energy cost savings. For this energy analysis and modeling project, our team provided integrated energy models of the proposed and baseline designs, as well as prepared the LEED energy credit documentation that accounts for a total of the needed 30 LEED points, which equates to over 37% of what is required to earn the LEED Platinum certification.

303 Battery is also pursuing the Living Building Challenge Petal Certification, and the Seattle Living Building Pilot Program. Both of these pursuits depend on the buildings net-zero energy status. Win-win!
