SEED Collaborative has teamed up with Method Homes for the construction of what it hopes will become the first modular building to pass the Living Building Challenge. The SEEDclassroom is designed to be a portable teaching space available at short notice, and yet one which meets its own energy and water needs.The SEEDclassroom is a place for children to learn and think about sustainability (SEED itself standing for Sustainable Education Every Day). Each 900 sq ft (84 sq m) building catches rainwater to be used in the sinks and basins, from which water is intercepted once again, and filtered through a "living wall" of edible plants. The classroom's energy is provided by rooftop solar power.
