Detailed Design
1 The Cooling Boulevard
Captured rainwater and district grey water supply fountains and other water features that will offer a reprieve from the hot summer sun, reducing overall campus temperatures and improving outdoor microclimates. Stormwater is cleansed and slowed through porous pavement, swale systems, and rain gardens and will be stored in large subgrade catchment basins to balance seasonal precipitation disparities. Native and drought tolerant vegetation minimize landscape irrigation demand and preserve supply for agricultural purposes.

7 All-Season Heat Sink
Housing exports surplus electricity to the district during the day. Housing and the dining facility offer a substantial waste heat resource from morning showers, meal preparation, sewage waste stream, and other domestic uses. Residences become a sink for office and classroom heat for evening heating needs.
PV panels installed on all South and some East and West facing facadesa and all roof surfaces. Parking garage has minimum energy load while providing surface area for PV array.
District waste heat is used for water heating in the Aquatics Center.

Natural systems waste nothing, with shared resources cycled through and between complex sub-systems and discrete entities. These systems are anti-entropic, bringing order from chaos, a whole that exceeds even the imagined the sum of the disparate parts, adding value through the process itself. Natural systems optimize efficiency, persist within its carrying capacity and contribute beyond perceived boundaries. Production, well-being, and regeneration are the metrics of success. HOMEOSTASIS looks to nature for guidance and does all possible to emulate what took millennia to master. Energy and water are shared resources that must be full taken advantage of, ebbing and flowing through sources and sinks, passed to and from opposing and complimentary uses and temporal demands. Indoor spaces nurture through optimal indoor air quality, ample daylight, and a connection to the outside and the community. Open space is crafted to encourage interaction and prioritize the pedestrian, creating refuge from the hot sun and the automobile. Large open spaces have layered functions, with catchment basins or ground source loops below playing fields and community spaces, tree canopies above. Plazas serve as gathering places and expressive conveyors of the hydrologic cycle. The waste stream is repurposed to provide essential resources: agricultural waste, manure, landscape clippings, food waste, and waste water solids are digested anaerobically to produce methane and then aerobically to yield compost which is returned to the land to begin the process anew. The campus is a complex web of give and take, balance, and health.

Optimized Orientation/ Shading for Solar Gain and Glare Control / Thin Floor Plates Balance Daylight from Two Sides
System Summary Buildings are oriented and massed to enable simple solar control for heat gain and glare while maximizing photovoltaic energy generation. Thin floor plates result in ample daylight and increased natural ventilation effectiveness. Subgrade labyrinths, or earth tubes, temper ventilation air supplied through low velocity high volume displacement strategies. When combined with radiant space conditioning systems, high levels of indoor air quality and comfort are achieved while reducing energy consumption. Ventilation heat recovery further reduces energy demand. Economizer systems take advantage of free cooling hours. Mass and phase change material are bathed with cool night air to reduce cooling demand the following day. District systems take advantage of economies of scale and minimize localized building systems.
