Hacienda has actively reduced the demand it places on the electrical system through upgrades that saw the installation of everything from energy efficient equipment to clean energy systems. Beyond the long-term benefit of cost savings from projects whose payback periods were measured in months, not years, Hacienda has significantly reduced the energy demand for its infrastructure.
In conjunction with the City of Pleasanton, Hacienda conducted energy efficient lighting retrofits throughout the park on selected features; most notably with the park's traffic signals, street lights, bus shelters and decorative lighting.
Hacienda also supports tenants who seek clean power and energy efficient upgrades. Many individual Hacienda projects have provided their own savings through a variety of retrofit programs.
Building energy upgrades are common throughout Hacienda and concerted efforts are seen on new construction to make buildings as energy efficient as possible. Several projects in Hacienda have pursued clean energy generation. Large solar arrays are located on three Hacienda sites and fuel cells are located at two sites. Cogeneration has also been used at two Hacienda projects to provide more efficient use of energy.
