In Seattle’s Belltown neighborhood sits the world’s first net-zero apartment high-rise (as certified by the International Living Future Institute). At 15 stories, 303 Battery offers 112 apartments, 27 of which are deemed affordable housing, along with a rooftop deck and ground-floor retail spaces. While its 506 solar panels on the roof, residential balconies and south-facing wall are an impressive feature, 303 Battery’s most unique component is perhaps the building itself – which is constructed of a proprietary premanufactured modular system within a steel-frame column and beam exoskeleton.
As the brainchild of Sustainable Living Innovations (SLI) in partnership with DCI and CollinsWoerman, the SLI system is a kit-of-parts designed to improve speed of construction, particularly on tight site locations like city orphan lots that otherwise lack the capacity to accommodate typical construction activities.
