Taking a Lean approach to vertical farming

Dan Albert’s first exposure to vertical farming came in 2008 during a design competition for the U.S Green Building Council’s annual conference. “The architecture firm I was working for at the time in Seattle, Wash., sponsored a team of young designers to develop a conceptual architectural design that met the newly developed Living Building Challenge,” Albert said. “The concept of the competition was to design a carbon neutral building that was self-sufficient. The building wouldn’t consume any more energy or water that was found on the site and would achieve a high level of sustainability. During the development of this design the vertical farm idea really captivated my interest and became one of the main drivers for this conceptual building.”

The best greenhouse strawberry yields occur during March and April.
