(SLI Image) Sustainable Living Innovations, a Seattle tech company that’s created a new way to build commercial structures, broke ground Thursday on a 15-story development that’s pegged as the world’s first “net zero energy” high-rise apartment building. The 112-unit building will run off of solar power and batteries, and includes 27 affordable apartments. It’s being constructed with a patented design that uses panels manufactured at a plant in Tacoma, Wash. that come preloaded with electrical wiring, plumbing and mechanical equipment.
