4TH STREET RESIDENCE HALL WATER: Reduction, Collection, Treatment, ENERGY: On-site Harvesting WASTE: Reduce, Re-use, Recycle 3. Low-Flow Fixtures Simply installing low-flow fixtures reduces the water demand from 53.58 gal./person/day using typical fixtures compared to 19.47 gal./person/day with low-flow fixtures, a 64% reduction. 4. Hydroponics Vertical farming produces crops that use 70% less water than conventional farming and produces 10x the amount of food with the same footprint. 1. Constructed Wetland A sub-surface constructed wetland provides treatment of up to 7,275 gal/day of wastewater to be re-used for toilets, irrigation, and laundry meeting well over 100% of non-potable water demand. Subsurface flow wetland eliminates odor and prevents contact with the water. All water flows beneath layers of planted gravel so that no surface water is exposed. 2. Green Roof 22,000 sf of extensive green roof planted with native prairie grasses will reduce stormwater runoff, reduce urban heat island-effect, moderate interior temperatures, increase biodiversity, and enhance the aesthetic quality. 5. Rainwater Harvesting Runoff from roofs will be captured and stored in cisterns to be used for irrigation and hydroponic farming. Excess rainwater infiltrates through impervious surfaces and is further channelled into the retention pond 7. Solar Thermal Collectors Designed to meet 75% of domestic hot water load and 30% of heating load. 9. Hydroponics On a large scale, the hydroponic farming technique will help alleviate agricultural runoff, restore cultivated fields back to their native ecosystems, and reduce energy input and carbon emissions from food cultivation, harvesting, and transportation. 6. Photovoltaics 17,550 sf of photovoltaic panels generate 714,240 KBtu, meeting 30% of electric load annually. 8. Daylighting Narrow floor plates (48’) and 30% glass to wall area allows most of the interior spaces to be naturally lit. This will reduce energy consumption for electric lighting by 25%. 13.

Subsurface flow wetland eliminates odor and prevents contact with the water. All water flows beneath layers of planted gravel so that no surface water is exposed.
