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),[1] plus all-electric heating system, chilled beams and radiant panels for cooling, high daylight autonomy, transportation management, and rainwater recycling.
David and Lucile Packard Foundation Headquarters is located in Los Altos Northern California, on the south end of San Francisco Bay.
David and Lucile Packard Foundation Headquarters is orientated 40 degrees off true north to fit in the urban fabric.
The building is monitored by indoor sensors that send direct reminders to occupants to open the windows when natural ventilation mode is on.
In the winter, when the temperature drops to a certain degree, the building will be preheated to 23 °C (74 °F) in the early morning by the combination of air handlers and heat water beams in specific areas in the office spaces.
Water is stored and cooled in two 25,000 gallons underground tanks, and in the morning, it is pumped into the chilled beams to spread out to specific interior spaces.
Acoustic satisfaction is comparatively low due to open areas in the office space and hard surfaces of radiant floors and ceilings; people concerned about overhearing private conversation on the phone and with the neighbors.
Consistently reflecting the same concern of open areas, the office layout survey also shows that people think the partitions and walls are too low or too transparent and feel the lack privacy in the working spaces.
