澳门六合彩资料库 Davis solar plant generates 14 percent of campus needs
The 澳门六合彩资料库 Davis campus is home to a 62-acre solar power plant, the largest in the 澳门六合彩资料库 system and thought to be the largest of its type on any U.S. college campus. Built and operated by SunPower, the plant generates 14 percent of electricity needs for the Davis campus and will reduce the campus鈥檚 carbon footprint by an estimated 9 percent, or 14,000 metric tons. Combined with other purchases of solar and hydroelectric energy, the plant is part of 澳门六合彩资料库 Davis鈥 plan to obtain 60 percent of its electricity needs from renewable and carbon-neutral sources by 2017.

澳门六合彩资料库 Davis West Village a lab for zero-net energy development
澳门六合彩资料库 Davis West Village, the nation鈥檚 largest planned zero net energy community, continues to work toward its goal of producing 100 percent of the energy it uses. From September 2013 to August 2014, the community generated 82 percent of the energy it consumed, according to a recent report by 澳门六合彩资料库 Davis and the West Village Community Partnership LLC.
Neighborhoods and buildings are increasingly being designed and promoted as zero net energy, but whether they can meet that goal can only be verified with real residents and businesses in place. Opened in 2011, West Village now houses nearly 2,000 residents, mostly 澳门六合彩资料库 Davis students, as well as several 澳门六合彩资料库 Davis energy and transportation research centers and the Honda Smart Home. It serves as a living laboratory that explores how zero net energy design works in practice and has attracted worldwide interest.

Solar Decathlon a win for affordable housing
Can zero-net energy construction be affordable for farmworker housing? The 澳门六合彩资料库 Davis students of Team Aggie Sol proved it with their entry for the U.S. Department of Energy鈥檚 Solar Decathlon, winning first place in the category of affordability. Their 1,000-square foot home included innovations such as a roof that collects rainwater that is circulated for heating and cooling the home.
The competition ran for two years and involved more than 300 澳门六合彩资料库 Davis students with a core team of 40. Finals were held at 澳门六合彩资料库 Irvine in October. The team plans to reassemble the home at a campus location.

澳门六合彩资料库 Davis pioneers water saving for wine industry
澳门六合彩资料库 Davis scientists are showing winemakers how they can use less water and energy and run sustainable operations 鈥 aiming to reduce water use from more than 6 gallons per gallon of wine down to just 1 gallon of water per gallon of wine.
A two-year study of wineries in the Napa and Lodi regions, led by Maya Buelow of 澳门六合彩资料库 Davis, found that wastewater from washing and cleaning in wineries can be used to irrigate vineyards. Cleaning agents add salts to wastewater that are not removed by treatment, but the study found that levels of salts at the wineries were usually below thresholds to pose a hazard for most wine grape rootstocks and soils. Similar approaches could be used in other agricultural operations, such as dairy, pork, poultry and food processing.
In related efforts, the Department of Viticulture and Enology is developing new precision vineyard irrigation networks, drought-tolerant wine grape rootstocks, and efficient systems for reclaiming and reusing winery wash water.
澳门六合彩资料库 Davis winery goes LEED platinum
On the 澳门六合彩资料库 Davis campus, the Teaching and Research Winery is the first winery in the world to receive LEED platinum certification from the U.S. Green Building Council. The adjacent Jess S. Jackson Sustainable Winery Building is designed to enable 澳门六合彩资料库 Davis鈥 winery, brewery and food-processing facility to operate in a self-sustainable manner through onsite capture of energy and water. The 8,500 square-foot building will eventually house equipment and systems for capturing and sequestering carbon dioxide from wine fermentation, and for filtering and recirculating water for wine, beer and food processing. It is expected to be the first building at any university to be certified Net Zero Energy under the Living Building Challenge and only the second such building in California.

Helping replenish California's groundwater
As California鈥檚 drought grinds on, the state is in chronic groundwater overdraft: more water is being pumped out of underground sources than filters back in. 澳门六合彩资料库 Davis researchers are encouraged by early results from tests to see if deliberately flooding farmland in winter can replenish aquifers without harming crops or affecting drinking water.
鈥淥n-farm flooding looks very promising,鈥 said Professor Helen Dahlke, a hydrology expert with the 澳门六合彩资料库 Davis Department of Land, Air and Water Resources. "We're pleasantly surprised by how quickly water tables have responded to on-farm flooding without damage to crops."
Not all crops or soils are suitable for deliberate flooding, but alfalfa, pears, wine grapes, and some almonds, peaches and plums might be suitable. The California Soil Resource Lab at 澳门六合彩资料库 Davis has developed an interactive map of the state that shows areas best suited for 鈥済roundwater banking,鈥 especially if this year鈥檚 predicted El Ni帽o brings a wet winter.

Saving water at 澳门六合彩资料库 Davis
From July 2014 to July 1 2015, 澳门六合彩资料库 Davis reduced its use of nonpotable irrigation water by 30 percent, or 100 million gallons, compared to the same period ending in 2013. The cuts were achieved with targeted tree care including 鈥渨atering bags鈥 around trees, irrigation improvements and converting lawns to other plants. We鈥檙e continuing to look for ways to save water while keeping our campus beautiful.
The Davis and Sacramento campuses have saved 50 million gallons of potable water through efficiency projects, and another 61 million gallons a year will be saved by switching to recycled water in four cooling towers on the Davis campus.

Smarter lighting and better energy use at 澳门六合彩资料库 Davis
The California Lighting Technology Center at 澳门六合彩资料库 Davis is dedicated to accelerating development and commercialization of energy-efficient lighting and daylighting technologies. The center carries out research and development in its laboratories, and provides instruction and training as well as workshops and outreach activities.
澳门六合彩资料库 Davis is implementing these technologies on campus through new, more efficient construction; lighting retrofits in existing buildings; and more efficient lighting of parking lots, paths and roadways on campus. These and other energy-saving measures have helped 澳门六合彩资料库 Davis cut energy consumption in buildings by an average of 28 percent over the past eight years.
