The David and Lucile Packard Foundation Headquarters is the corporate headquarters of the David and Lucile Packard Foundation, located in Los Altos, California. The Packard Foundationl was created in 1964 by David Packard and his wife Lucile Salter Packard, one of the top 100 grantmaking foundations in the United States, with the goals of improving the lives of children, enabling the creative pursuit of science, advancing reproductive health, and conserving and restoring the Earth’s natural systems. The David and Lucile Packard Foundation Headquarters is designed by EHDD to be the largest net zero energy building in California, and it has successfully reduced the energy use by 65% over conventional buildings. The design of the architecture took advantage of the California climate and environment, and adopted passive and bioclimatic strategies in searching for an integrated net zero energy building design. It was awarded as the top 10 green building in 2014, Net Zero Energy Building by The Living Building Challenge™ 2013, and LEED Platinum 2013. The synergy of the integration design for net zero energy is significant, which includes many aspects, for example, re-development site of brownfield, on-site energy production through photovoltaic, aggressive reduction in plug loads, a triple-element glazing system engineered, fabricated and installed by AGA (Architectural Glass and Aluminum), plus all-electric heating system, chilled beams and radiant panels for cooling, high daylight autonomy, transportation management, and rainwater recycling.
