saltlakecity live-grow: self-sufficient living WHY are home and business occupants so negligent with their water and energy usage? Drinkable water is being wasted for lawn irrigation, flushing toilets, and for landscaping and mass amounts of energy are being consumed to purify and manage waste water. This design reduces the inappropriate use of drinkable water through integrated site design and water efficiency to minimize water usage. Located within a brownfield site along the Surplus Canal (fed by rivers, canals, stormwater, and snow runoff that drains into a dead sea – the Great Salt Lake) in Salt Lake City, Utah, this sustainable community with refugee housing and low/middle income families approaches design to not only house but also feed and employ the building occupants as well. Residents promote healthy landscapes through rainwater gardens, grey water reuse, biofiltration ponds, and blackwater subsurface wetland systems. In addition to using water-wise systems, the residents learn to become self-sufficient in food production through four types of gardens as their skill sets develop. Each tier of gardening educates the residents to become professional agriculturalists. Each home provides a sense of visual continuity yet defines personal space. This is achieved through prefabricated, modular design. This allows for flexibility in design and site location yet maintains a feeling of equality and democracy since no home is larger than another. Each home is equipped with innovative passive designs to reduce energy and water use, making them more resilient to shifts in availability of water, energy, and climate change.
