    • The David and Lucile Packard Foundation 343 Second Street Building, Los Altos, California
    • The Packard Foundation has a long-standing commitment to environmental sustainability. Our headquarters building is the physical manifestation of our efforts to “walk the talk” and live the values of sustainability right here at home. The building has achieved Net Zero Energy BuildingTM and LEED® Platinum (Leadership in Energy and Environmental Design) certifications. Photo © 2012, Jeremy Bittermann, Courtesy of EHDD
    • There are many personal touches throughout the building The reception desk was crafted by a Packard family member from a single piece of wood from a 600 year- old fallen Redwood tree at the family’s Big Sur Ranch. The painting behind the reception desk resembles the area around the Packard family’s San Felipe Ranch. Workstation partitions were designed from photos taken at San Felipe Ranch.

    • The 49,000 square foot building generates more than enough electricity through solar panels to meet its annual energy needs, earning it Net Zero Energy Building certification. Photo © 2012, Terry Lorant
    • Heating 16% Cooling 17% Ventilation 12% Lighting 32% Hot Water, 2% Plug Loads 16% Misc. 5% • Produced 418 MWh of our own energy through solar panels • Consumed 351 MWh of electricity thereby reducing our energy use by about 55% • Reduced lighting by 30% • Reduced HVAC, including 75% savings in fan energy • Reduce plug loads by 30% Typical California office building this size uses 725 MWh of energy per year To reach NetZero Energy in our first year of occupancy, we:
    • The building design, consisting of two long narrow wings surrounding a center courtyard, reduces energy consumption by maximizing the use of daylight. This allows for 30% reduction in the amount of energy consumed by artificial lighting.
    • The building was designed to maximize the use of natural daylight. Automated systems throughout the building measure free, natural light and then automatically dim or brighten artificial light as needed. Light shelves project natural light farther into the space and reflect it off the ceiling to diffuse daylight throughout the space. Photo © 2012, Terry Lorant
    • Each wing of the building has a distinct theme Glass etchings of oaks, a burgundy color scheme and woodland-themed adjacent courtyard landscaping characterize the Woodlands Wing. The Grasslands Wing is decorated with etchings of grasses and orange accents and connects with a courtyard landscaped with native grasses. Photos © 2012, Terry Lorant
    • This meeting space connects different “neighborhoods” of offices and facilitates community building among employees. It was designed to bring the outdoors in, a concept David Packard loved. The floor is made of finished, recycled end-cut wood. “Connector” spaces facilitate community-building and bring the outdoors in Photo © 2012, Jeremy Bittermann, Courtesy of EHDD
    • Occupant sensors in each workspace automatically turn off lights and put computers and monitors to sleep when the space is not occupied. Energy-efficient LED task lighting is provided at each desk. Energy-efficient T-8 fluorescent bulbs are used throughout the building. Energy-Saving Features Throughout the Building
    • Triple-element windows help insulate the building. The windows are made of two panes of glass with one film in between and are filled with 1.5 inches of argon gas, giving them an R-7 insulation value, much greater than a typical window. Insulation value for the floors and walls is R-19 and for the roof is R-33.
    • Heating, Ventilation and Air Conditioning (HVAC) In cold weather, the building is warmed to a target temperature of 74 F starting three hours before employees arrive at work. Once the work day begins, the heating system then typically turns off because it is no longer needed. The building is heated by a combination of air handlers and, in certain areas, by heated water in the (chilled) beams.
    • Chilled Beam Air Conditioning In warm weather, water is chilled at night by a compressor-free cooling tower and stored in two 25,000- gallon underground tanks. During the day, water is pumped into the pipes that run through the beams. Three major air handling units pull in 100% outside air, then filter and dehumidify it. Air flowing across the beams is sufficient to cool the interior spaces.
    • Chilled Beam Air Conditioning The chilled water is moved through the system using variable speed pumps and pipes angled at 130 degrees, rather than typical 90-degree angles. This is much more efficient than standard practices, allowing for a 75% reduction in duct work and a 75% reduction in pump energy. Photo © 2012, Jeremy Bittermann, Courtesy of EHDD
    • When possible, we reduce energy consumption by operating in natural ventilation mode, with windows and doors open, instead of depending on HVAC systems. Photo © 2012, Jeremy Bittermann, Courtesy of EHDD
    • Dashboards and desktop alerts display weather conditions and indicate when it is okay to open doors and windows. Desktop Alert Wall-Mounted Dashboard
    • The 292W grid-connected array of 915 photovoltaic solar panels was designed to produce 275 MWh per year of electricity. In its first year of operation ending in July 2013, it produced 418 MWh, more than enough to cover our first year’s electricity consumption. Photo © 2012, Jeremy Bittermann, Courtesy of EHDD
    • Nearly 15,000 monitoring and control points are part of the building automation system. Our building engineer can diagnose problems and monitor and control everything from interior and exterior blinds, to plug loads, lighting, the heating and ventilation system and electric vehicle charging stations.

    • To achieve LEED® Platinum certification, we had to consider not only energy-efficiency but also waste, materials used, and water efficiency, among other factors. Our LEED application was awarded 94 points out of a possible 110, exceeding the 80 required for Platinum status. Photo © 2012, Jeremy Bittermann, Courtesy of EHDD
    • We deconstructed 95% of the existing building for recycling and re-use. A majority of the materials used in construction were sourced from within a 500 mile radius. A mix of slate and quartz stone, used throughout the building, was sourced from Mount Moriah on the border of Nevada and Utah. The Red Cedar exterior wood paneling is FSC (Forest Stewardship Council) certified from Oregon.
    • • Overhangs are constructed of FSC (Forest Stewardship Council) certified Douglas Fir. • Copper cladding on exterior and interior walls is architectural copper, which is made from 75% recycled materials. © 2012, Jeremy Bittermann, Courtesy of EHDD
    • All the doors throughout the building were created from Eucalyptus wood salvaged from the Doyle Drive construction project in the San Francisco Presidio. The trees were already going to be cut down and this provided the Foundation the opportunity to put these resources to good use.
    • 90% of the plantings in the courtyard and around the building are California natives. Irrigation, fed by on-site water collection, is primarily sub-surface or surface drip managed by an ET-based (evapotranspiration) controller. © 2012, Terry Lorant
    • The deciduous London Plane trees in the courtyard are not native but were selected for their height, shape and summer shading capabilities. Because they will not grow much taller, they will not interfere with the rooftop solar power production. Photo © 2012, Jeremy Bittermann, Courtesy of EHDD
    • The 25 year-old Live Oak tree at the building’s entrance was grown from an acorn in Clear Lake.
    • • Street-side rain garden landscaping helps improve San Francisco Bay water quality by reducing street runoff into the storm drains. • Rain gardens (planted depressions) can withstand extreme moisture and nutrient loading. They allow for runoff to be filtered by sediments and cooled before draining. • One of Lucile Packard’s favorite flowers, the Western Columbine, is planted throughout.
    • The Foundation expects to decrease its water usage by 40%, in part through using rain water captured from roof gutters and stored in two 10,000-gallon underground tanks. This “grey” water will be purified and sterilized before using for irrigation and toilet flushing.
    • The living roof is planted with a variety of shallow-rooting, low-growing succulents to simulate the look of the bluffs on the California coast. This is aesthetically pleasing and a habitat for birds and other native wildlife. In addition, it provides a heat sink to help keep the building cool in hot weather and helps with rain water collection. Photo © 2012, Jeremy Bittermann, Courtesy of EHDD
