The David and Lucile Packard Foundation
Headquarters Building: A study in sustainability
In its first year of operation, the David and Lucile Packard Foundation headquarters
building in Los Altos, California exceeded all expectations, meeting its zero energy target
three months early and becoming a net positive generator of energy.
Integral Group performed MEP engineering, commissioning, and post occupancy
verification and tracking of the building performance to ensure Net Zero Energy operation
for the building.
At the heart of this exceptionally green two-storey
office building is an extremely efficient chilled beam
heating and cooling system with a high efficiency
air source heat pump with thermal storage. Highly
efficient systems together with the building
envelope reduce energy demand by 60% over code
baseline, while the remaining required power is
supplied by on-site photovoltaic power generation.
The building operates in natural ventilation mode
for half the year. Thermal energy storage, chilled
beams, dedicated outside air systems, fully
dimmable lighting fixtures, and circuit-by-circuit
power monitoring are some of the facility's novel
features.
Post-occupancy feedback shows 97% of occupants
are satisfied with the building overall, and thermal comfort satisfaction ranks in the 96
th
percentile.
The success of the design was measured on several fronts. The current in-operation
energy use is 68.76kWh/m
2
/year, and this is expected to decrease further as enhanced
