REI Round Rock Store Employs the Sun

The REI Round Rock store has an exceptionally efficient heating, ventilation and air conditioning system and building envelope, more than 80 percent reduction of construction waste, green building education program and rooftop solar panel installation. Mounting on the green building success of its previous stores, including one in Boulder, Colorado, this second generation of green prototype store in Round Rock, Texas, is projected to consume 48% less energy than a typical store and generate a portion of its power from a solar panel installation and building integrated photovoltaics.

Seattle Aquarium Retrofits with Solar Hot Water

The Seattle Aquarium unveiled Seattle’s first solar hot water demonstration project 16 June 2009, a system that will reduce the Aquarium’s use of natural gas by preheating water used in the second floor café. Installed by A & R Solar of Seattle, the five solar panels will shrink the Aquarium’s carbon footprint by 2.5 tons of CO2 each year, and teach the Aquarium’s 800,000 visitors about renewable energy sources. “Sustainable energy is linked to sustainable oceans,” Aquarium Director John Braden said. “Over 200 years of increasing CO2 emissions have carbonated the oceans and increased its acidity, threatening marine food webs, including plankton, shellfish, fish, birds, mammals and humans. With this solar project, we hope to provide a model of sustainability that can inspire our visitors and other zoos and aquariums to do what they can to take Climate Action Now.” Read more and see pix at SOLARIPEDIA.com.

Tethered Sails Power Cargo Ships with Wind

It’s an idea that has been tested: a giant sail is attached to a heavy cargo ship, or smaller boat, to capture wind power, thereby reducing fossil fuel consumption, costs and pollution. One company, SkySails, reports that its kite sail will help reduce annual fuel costs by ten to 35 percent, with fewer harmful carbon emissions. The large towing kite resembles a paraglider and is shaped like an aircraft wing to enable it to take advantage of different wind directions. It operates at 100-300m above surface level - much higher than a normal sailing craft - where winds are stronger and more stable. The kite can be used in winds of 12-74km/h (7-40 knots) and not just when the wind is blowing directly from behind the ship. At SOLARIPEDIA.com, we look at two different kite systems from two companies, SkySails and KiteShip. Read more and see pix

Solar Retrofit in UK Works Despite Clouds

Contrary to popular belief, light levels in the UK are sufficient to make photovoltaic cells viable throughout the country, with photovoltaics generating power even on cloudy days. In addition, solar energy works well in built-up urban areas and can be retro-fitted to existing buildings and houses relatively cheaply, to produce truly local power. The CIS Tower in Manchester, UK, provides an example of how a 1962 building was retrofitted with photovoltaics to provide part of the building’s power. The building was clad with a total of 7,244 Sharp photovoltaic panels generating 390kW of energy and began feeding electricity to the National Grid in November 2005. The building also has 24 wind turbines on the roof, and combined with the solar provide 10% of the total power used by the building. Read more about it and see photos at Solaripedia.com.
