Learning with Sun and Nature at IslandWood

IslandWood, an outdoor learning center near Seattle, Washington, targets students from schools on free and reduced lunch programs for its School Overnight Program where they are immersed in experiences with nature and sustainability. The site and the buildings are designed to be sustainable, featuring solar meadows and building orientations that maximize passive solar gain. High performance windows optimize solar heat gain and reduce energy consumption. Natural ventilation replaces air conditioning, with operable window openings and skylights for maximum air circulation. Rainwater is collected from the roofs of several buildings and used for landscape irrigation. A Living Machine treats wastewater by using plants to filter impurities. Photovoltaics provide power and water is heated by the sun. Even trees that were cleared to make way for buildings and solar access have been cut, dried and milled and then used for exterior siding and interior trim throughout project.

Lighthouse Zero Energy Home (UK)

The Lighthouse Zero Energy home in the UK has a simple, “barn-like” form with a 40 degree pitched roof that includes solar panels and rainwater harvesting. It boasts high levels of thermal insulation, passive cooling and ventilation and biomass boilers. Biomass boilers run on organic fuels such as wood pellets and count as zero-emission because the amount of carbon dioxide they give off when they are burned is offset by the amount that was absorbed when the crop was grown. The house also has a waste separation system that allows combustible waste to be burned to help provide power.

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.
