This idyllic 15-acre farmhouse is the worlds second Living Building residence

Comments Off on This idyllic 15-acre farmhouse is the worlds second Living Building residence

A picturesque 15-acre farmhouse in Ann Arbor, Michigan was just officially crowned the world’s second “Living Building” residence by the International Living Future Institute (ILFI). The owners of Burh Becc at Beacon Springs , Tom and Marti Burbeck, spent five years working with a team of 20 designers, engineers, architects and sustainability experts to transform their 2,200 square foot home into an icon of truly sustainable living that gives more than it takes. The beautiful farmhouse, whose design was inspired by traditional Tuscan farmhouses, has a large living space of 2,200 square feet. Additionally, the property has a 2,400 square foot barn and workshop. The farmland had been previously depleted due to years of commodity farming. Following the Living Building criteria, the land was carefully revamped with permaculture farming methods using an integrated system of agriculture, horticulture and ecology, creating a system that will be regenerative for centuries to come. The Burbeck’s not only use these farming methods to grow their own food, but they also provide healthy food for the local community – and for those with limited access to fresh produce. Related: 9 of the most impressive Living Building Challenge certified projects To create a net-zero energy design , the home is equipped with clean energy generation through a 16.9-kilowatt solar array, which provides electricity to the home and back into the grid. Additionally, a passive solar system works with a very tight thermal envelope and a tall cooling tower to minimize heating and cooling needs. A closed-loop geothermal system provides radiant floor heating during the cold Michigan winters. For water conservation, the home uses a rainwater and snow harvesting system to be water net-positive . A rainwater collection system reroutes to supply 7,500 gallons of in-ground cisterns, used for non-potable water. An on-site well provides potable water at the moment to comply with local building codes, but the home is installed with a future-ready potable rainwater filtration system. After more than three and a half years designing the reformation, 18 months in construction and a year of performance auditing, Burh Becc at Beacon Springs Farm was awarded the Living Building Challenge certification in December 2017. Additionally, the home has been awarded a Platinum LEED Certification. When the Burbecks were asked why they took on such an ambitious project, they explained that it just made sense to their lifestyle. According to Marti Burbeck, “As we looked at the criteria for LBC certification we thought, why not go for it. If our goals include helping to change peoples’ relationship with the environment and to change building philosophies, we should start with our own project, and then become advocates.” Now that they’ve achieved their dream of converting Burh Becc into an icon of sustainability, they’re on their way to becoming advocates. The couple plan to host educational workshops and house tours to educate the community, the building industry, government officials, and anyone who will listen about the benefits of truly sustainable living. + Burh Becc at Beacon Springs + Architectural Resource Via CSR Wire Images via Burh Becc at Beacon Springs

World’s first floating wind farm performing better than anticipated

Comments Off on World’s first floating wind farm performing better than anticipated

The 30 megawatt Hywind Scotland floating wind farm started operating last fall , and Statoil recently said the farm, a world first, “performed better than expected in its first three full months in production.” The floating farm, a Statoil and Masdar project, has already survived a winter storm, a hurricane , and wave heights of around 27 feet to power around 20,000 households in the United Kingdom . 45 to 60 percent is the “the typical capacity factor for a bottom fixed offshore wind farm” during the winter, according to Statoil. But Hywind Scotland beat that figure with an average of around 65 percent in November, December, and January, the Norwegian power company said. This means the floating wind farm “was producing 65 percent of max theoretical capacity.” Related: The world’s first floating wind farm just switched online That’s a win for the floating power plant , which has already encountered brutal winter weather. Hurricane Ophelia in October saw wind speeds of 80 miles per hour, and Storm Caroline in December saw gusts of 100 miles per hour and waves of around 27 feet. The wind turbines were switched off for safety during the worst winds, Statoil said, but automatically started operating quickly after. According to the company, “A pitch motion controller is integrated with the Hywind turbine’s control system and will adjust the angle of the turbine blades during heavy winds which mitigates excessive motions of the structure.” Statoil senior vice president of offshore wind operations Beate Myking said in the statement, “We have tested the Hywind technology in harsh weather conditions for many years and we know it works. But putting the world’s first floating wind farm into production comes with some excitement. Therefore, it is very encouraging to see how well the turbines have performed so far. Hywind Scotland’s high availability has ensured that the volume of electricity generated is substantially higher than expected.” Statoil New Energy Solutions executive vice president Irene Rummelhoff said they are seeking new opportunities for the technology, and see potential in Europe, Asia, and North America’s west coast. Statoil and Masdar aim to cut the costs of energy from Hywind Scotland down to 40 to 60 Euros per megawatt-hour by 2030 to make it “cost competitive with other renewable energy sources.” + Statoil Images via Øyvind Gravås/Woldcam/Statoil ( 1 , 2 )

Green-roofed holiday home is fashioned from three shipping containers

Comments Off on Green-roofed holiday home is fashioned from three shipping containers

Led by a desire to reduce landscape impact, Melbourne-based Studio Edwards turned to cargotecture for a sustainably minded getaway on the Surf Coast in Victoria, Australia. Raised atop stilts on a steep slope, House 28 was fashioned from a trio of 20-foot shipping containers sourced from nearby Port Melbourne. In addition to minimized site disturbance, the green-roofed holiday home uses a rainwater catchment and filtration system to gather water and features double-glazed windows and doors to increase energy efficiency. Set overlooking the Wye River and Australia’s Otway Coast, House 28 is securely anchored to the hillside by steel stilts and deep concrete pile foundations. The architects joined two of the containers to form one long module housing the entrance, a spacious living area, and open kitchen with dining, while the other container comprises two bedrooms and a bathroom. The containers were angled towards one another and connected with a blackbutt timber deck. Related: Shipping container delivers heightened drama to a modern island home For a rugged finish, the containers were externally insulated and clad with galvanized steel sheeting. In contrast, the minimalist interiors are lined with marine-grade plywood for a warm feel. Full-height doubled-glazed windows and doors overlook the ocean to the south and keep the narrow buildings from feeling constrained. A garden of native dichondra covers the roof providing extra thermal insulation and rainwater filtration. + Studio Edwards Via Dezeen Images by Tony Gorsevski
