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.

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

Ephemeral timber pavilion doubles as sculpture and film venue in Portugal

Comments Off on Ephemeral timber pavilion doubles as sculpture and film venue in Portugal

This elegant ephemeral pavilion does double duty as a film venue and sculpture that complements the garden grounds of Portugal’s Serralves Museum. Porto-based Diogo Aguiar Studio designed the architectural object, which is made up of curved timber partitions that come together to form two concentric spaces: the main film viewing area and the interstitial space. Diogo Aguiar Studio was selected to design the pavilion, which formed one of Serralves Museum’s five temporary structures for the architectural exhibition Live Uncertainty, 32nd Bienal de São Paulo that concluded this Sunday, February 18. Like depA’s pavilion design for Serralves, Diogo Aguiar Studio’s contribution is a minimalist affair and its all-timber cladding complements rather than detracts from the wooded surroundings. The pavilion nucleus is a dark space where the film “Os humores artificiais” (2016) by Gabriel Abrantes is shown. The addition of a secondary curved skin helps control the amount of daylight that reaches the interior and adds a sense of mystery: the three openings on the outer facade do not match up with those in the antechamber and force visitors to walk along a mulch pathway. The journey through the pavilion to watch the film thus becomes an experience in itself. Related: Mirrored pavilion all but disappears into nature As the architects put it: “Contributing to the control of natural light in the interior space, the juxtaposition of two façade-plans, curved and parallel, which alternately open double-curved arc spans, guides the visitor to walk through the immersive space of mediation – as an antechamber-path – without revealing the central nucleus – as a space-enclosed – the projection place.” + Diogo Aguiar Studio Via ArchDaily Images © 2017 Francisco Nogueira Architectural Photography
