One example of a proposed sustainable "green" building is the Ecolaboratory building to be built on the 7,200 square foot P-patch in the Belltown neighborhood of downtown Seattle. Conceived by Weber Thompson, it is proposed that the main living units of the building be constructed of recycled shipping containers. All water, including black and gray water, is to be recycled for the use of residents and landscaping water needs. Residents will be able to individually control the amount of their natural ventilation by the design of what are referred to as "earth tubes." Solar hot waters panels will provide for the heating of hot water. Also providing energy for the building will be photovoltaic solar panels, biomass conversion, and even hydrogen fuel cells - to generate electricity.
