The six integrated building systems taught throughout the Pangea Textbook Series — Structure, Energy, Water, Liquid Waste, Food, and Community — take on new dimensions when designed at the community scale rather than the individual building level.

Structure at the community scale means thinking about building clusters, shared walls, covered walkways, community gathering spaces, and the choreography of how people move through space together. Energy means a community microgrid with shared generation, storage, and distribution infrastructure. Water means a community-scale rainwater catchment and storage system, shared filtration, and coordinated irrigation. Liquid waste means constructed wetland systems serving multiple households. Food means integrated growing zones that produce for the whole community. And the sixth system — Community itself — means the human governance, economic, and social systems that tie everything together.
