Sanyo’s solar arkThis stunning piece of architecture is Sanyo’s Solar Ark, one of the world’s biggest solar energy generation systems.

Designed with a vision of “an ark embarking onto a journey towards the 21st century” in mind, it’s 315 metres long, 37 metres high and covered with 5,046 solar battery panels, which produce an annual electrical output of 53,000kWh.

At the building’s centre is a state-of-the-art science museum, which opened to visitors in April 2002, that aims to create interest in environmental issues and photovoltaic science.

The Ark is fitted with more than 77,000 red, green and blue LEDs that turn it into a huge illuminated presentation panel on which a variety of visual images can be created. This must be quite a spectacle for people travelling on the JR Tokaido bullet train in Gifu, Japan, as the railway line passes close to the Solar Ark.

World’s greenest building

Aldo Leopold centreThe Aldo Leopold Legacy Centre in Wisconsin is the world’s first carbon neutral building. It was certified by the US Green Building Council this year.

The centre produces more energy than it consumes. About half the 12,000-square-foot building’s energy saving comes from low-tech solutions such as using natural light, insulating the walls and ceilings and allowing air to flow freely.

The centre generates its own electricity with a photovoltaic system on its roof. The 198 panels and can generate 60,000 – 70,000 kilowatt hours of electricity a year. The system is connected to the power grid so extra electricity produced in summer can be credited towards any electricity the building may need to buy during the winter.

The building also uses geothermal energy and a system of earth tubes are used ventilation.
