The first spec home in the Pacific Northwest to meet Passivhaus standards is in the Columbia Station green micro-community built by the award-winning design+build boutique firm, Dwell Development. Passivhaus is an energy standard that is more difficult to achieve than LEED with respect to energy efficiency. Homes that meet the Passivhaus standard must reach thermal comfort levels by postheating or postcooling fresh air without necessitating recirculation.
Hayden Place, located in Culver City, California (a suburb of Los Angeles) was designed by Cuningham Group Architecture for REthink Development to serve as the international design firm’s new home office space.
Targeted for LEED Gold, the sustainable features of the 11,650 square-foot building, which was converted from an existing warehouse, include repurposed shipping containers, light sensors, efficient energy systems, natural lighting and fresh air “trickle” ventilation. Additional air filtration is provided by an indoor garden that features adaptive and native plants and is maintained by office employees.
