The accessory dwelling unit (ADU) market is alive and well in the Concordia neighborhood of Portland, Oregon. People like these tiny structures — sometimes referred to as backyard cottages, granny flats, or laneway houses — because they can be leased out or used to accommodate an expanding family situation. And, as these structures grow in popularity, they’re getting greener, too. For instance, check out this high-performance ADU built by Hammer & Hand and designed by Departure Design.
This is Morning Sun, a near net-zero energy home completed at the end of December 2009 for owners Doug and Emily Boleyn. The high-performance abode — designed by Matthew Daby of m.o. daby design llc and built by Cellar Ridge Custom Homes — received LEED Platinum certification, Oregon High Performance Home certification, and an Energy Performance Score of 31, making it one of the most decorated green projects in Happy Valley.
This is the first permitted shipping container house in the Mojave Desert near Joshua Tree, California, according to a statement by the architect, Walter Scott Perry, principal of ecotechdesign. The home, also known as The Tim Palen Studio at Shadow Mountain, was built with re-purposed shipping containers and some impressive green elements such as a steel shade system, a living roof, and a 10,000 gallon water storage tank.
Seattle has its fair share of LEED Platinum homes, but this is the first LEED Platinum single-family home in the state of Washington outside of Seattle. The Bainbridge Island home, blending style and sustainability, was designed by Coates Design Architects for owners Ed and JoAnne Ellis, who wanted an exemplary, modern, green home.
This ultra-efficient home is repaying owner Scott Shackleton with money from putting excess electricity into the grid. Located on a narrow lot in downtown Raleigh, North Carolina, the shotgun-style home generates nearly two-times the electricity it uses with a 4.7 kW solar array on the roof. That plus about 85% of domestic water is pre-heated with solar thermal, resulting in more energy savings.
This year’s HGTV Green Home is in the popular Stapleton infill development of Denver, Colorado. The New Urbanist community features nothing but Energy Star homes that are about 30% more energy efficient than standard homes and 20% more water efficient than typical Denver households. But the HGTV Green Home 2011 steps things up a notch with a LEED Platinum certified project — it’s one of about 40 in the state.
