ROOM 105 Saving Water, Saving Energy Across the globe, the connection be- tween water and energy is increasingly apparent, and with drought conditions emerging, the need to conserve both has grown critical. The issue is two-fold as utilities relying on water to gener- ate electricity struggle, and electrical demand for water-related usage esca- lates. In California, 19% of the electric- ity goes into water-related uses, and with severe drought conditions water levels are reaching critical lows. As stated by the Association of California Water Agencies, dual programs ad- dressing energy and water conserva- tion needs are still uncommon, despite the fact that saving water saves energy. This session will review efforts being made globally through the Watergy program to address utility concerns, and bring it home to California schools and communities. By addressing recommendations for schools, we can reach tomorrow’s consumers: students. These recommendations are practical, cost-effective ways to quickly begin conserving our two precious, intercon- nected resources: water and energy.

ROOM 204 Agriculture and Water Sustainability: The Australia Case Study Agriculture is a critical piece of the water puzzle because more than 70% of the planet’s freshwater is used for ir- rigation. Unfortunately large volumes of water are lost in irrigation delivery net- works, most of which consist of aging infrastructure and antiquated technolo- gies. In Australia, approximately 30% of water that enters unmodernized open canal irrigation systems is unaccounted for or lost. This session tells the story of the worst drought in Australia’s record- ed history and the National response to this drought. The drought created an ecological disaster, devastated agri- cultural production and threatened the water supply of the City of Melbourne. The response was an investment in in- novative new technology and manage- ment practices to modernize agricul- tural delivery networks. The distribution efficiencies of irrigation networks were increased from 65% to 85%. In excess of 182,000 acre feet of water are being recovered each year, providing more water for farmers, the environment and urban consumers.

WEDNESDAY, APRIL 9
9:00 am- 10:15 am ROOM 101-102 Zero Net Energy Buildings: Practices, Policies, and Performance
Zero Net Energy (ZNE) buildings pro- duce as much energy as they consume over the course of a year using clean on-site renewable energy sources. They are being constructed in most climate zones of the United States using readily available strategies and technologies. In some cases, they are being built at little or no incremental cost over comparable conventional quality buildings. California is nearly ideal for ZNE and is leading the nation in this approach. However, this emerg- ing concept and is not widely known and there are few structures that have been measured and verified. Yet, poli- cies are being established today that will profoundly alter the way we design and construct buildings in the state with the objective that all new buildings will be ZNE by 2030. This session will explore the various definitions of ZNE, policies and regulations that influence ZNE building design, the role of energy modeling plus examples of constructed and proven ZNE buildings.
