Shizen Condo: 100% Solar and Biodiesel Power
Wow, impressive. This condominium complex, called Shizen (Japanese for nature) is under construction in Portland. It will make use of solar cells and a biodiesel generator, to provide all the electricity, heat and hot water for the building.
Shizen's solar array will be rated at 23 kilowatts, and will generate one third of the building's annual electricity. A biodiesel-fueled microturbine will generate the other two thirds, and will also provide hot water for the residents as well as space heating. These two renewable sources make Shizen a zero energy project. Water conservation will also in effect — there will be a 25,000 gallon cistern under the parking level, which will provide water for flushing toilets and irrigation.
