SLI ‘Tops Out’ 303 Battery, a Pre-Fab Tower

SEATTLE -- Sustainable Living Innovations (SLI) has installed the final steel beam and manufactured building panel for its 15-story, 112-unit apartment building under construction in Seattle’s Belltown neighborhood.

SLI installed the first steel beams and panels in October 2021.

SLI’s patent-protected technology platform is a new way to build, using wall and floor panels that are manufactured with electrical wiring, plumbing, mechanical and fire safety equipment pre-installed. By designing and manufacturing buildings as a product similar to cars and airplanes, SLI’s high-rise buildings go up faster and meet the world’s highest standards of sustainability.

“This is an important milestone for sustainability, our company, our employees, our investors and so many others who have supported us,” said Arlan Collins, CEO of SLI. “303 Battery is tangible proof that we can achieve the highest levels of sustainability using our technology.”

The installation crew, SLI employees, investors and other partners signed the beam and panel before the tower crane swung both of the building’s final structural pieces into place.

Carrie Cassidy, Chief Construction Officer of SLI said, “It’s been a lot of hard work to have reached this point. My deepest thanks to our dedicated team of partners who made this day possible.”
303 Battery will be the world’s first multifamily tower to meet the stringent net zero energy requirements set by the International Living Future Institute’s Living Building Challenge program, the same organization that certified Seattle’s Bullitt Center.

Features include solar on the building’s roof, exterior walls and balconies in each unit, greywater and waste heat recovery systems, ultra-efficient hydronic heating and cooling systems, regenerative elevator motors, distributed DC power systems, and SLI’s advanced network systems and data management platform to ensure optimal building operations.

303 Battery will be completed in December, with tenants anticipated to move into the building early 2023.
303 Battery includes approximately 900 panels that were manufactured in SLI’s Tacoma, Washington facility and are being assembled on site. Ten primary panel types were used in the construction of 303 Battery, with panels for walls, floors, and ceilings of each room – living room, kitchen, bedroom, bathroom – and specialized elevator panels.

Sustainable Living Innovations (SLI) is a building technology and product development company that is disrupting the world’s largest addressable market by reimagining how buildings are designed, built, and operated. SLI’s finished buildings are more sustainable, as well as faster to design and complete versus conventional buildings. The company employs more than 80 people with offices in Seattle and Denver and operates a showroom in Seattle and a manufacturing facility in Tacoma, Washington.
