Project Details

To accommodate the growing air transportation needs of the San Francisco Bay Area, the Port of Oakland is expanding its passenger terminal facilities. The Oakland International Airport Terminal Expansion Program is a phased program, which includes the roadways to the airport, renovation and expansion of the existing Terminal 2, and the addition of Terminal 2 Mechanical Building. The City of Oakland set a goal to achieve 50 percent energy savings compared to the 2001 Title 24 California Energy Standard. The airport has some unique features such as high ceilings, significant west-facing glazing area, varying occupant density and large interior zones without any daylight, which formed the basis of identifying appropriate energy efficiency measure, such as daylight and lighting design, and optimizing HVAC design and control to minimize energy during low occupancy periods. The total package of recommended measures was projected to save approximately 57% in annual energy consumption relative to Title-24 baseline building. However, some measures were not adopted which dropped the savings margin to 36% compared to the Title-24 baseline building.

Energy Saving Features

Efficient lighting design through efficient layout and energy saving fixtures.
Installing CO2 sensors to control ventilation rate based on number of occupants in the space.
Reducing fan energy consumption by installing low-face-velocity coils, low-loss fittings, larger ducts, and dynamic static pressure controls.
Installing variable air volume systems in place of multi-zone air handling systems with reheat.
Installing variable speed drive in chillers to reduce energy consumption during low load periods.
Optimizing chiller size to avoid over-sizing chillers.

Daylighting and fenestration recommendations that were implemented include the following:

Optimizing fenestration area and glazing type to increase daylight and reduce solar gains.
Optimizing exterior shades and light shelves reduce solar gains and improve daylighting in perimeter zones. Installing skylights to introduce daylighting in interior zones.
Installing dimming daylight controls to reduce lighting energy based on daylight availability.
