Weber Thompson's design for Eco-Laboratory won the Natural Design Competition at the annual Greenbuild International Conference. The concept high-rise includes rainwater collection, black water to graywater conversion features and is net-zero energy. The high-rise is virtually a self-contained sustainable community.
Perhaps the most unusual feature of the design is the energy-generation system. It starts with methane (produced from waste), which runs the hydrogen fuel cell. The fuel cell and other systems provide electricity and heat water.
