Santa Clara Tower I
3945 Freedom Circle
Santa Clara, CA 95054
Map It!


Santa Clara Towers consists of two 11-story office towers with granite fa?ades. The property was developed by McCandless Management, with the 3945 Freedom Circle tower built in 1985. Between the two buildings sits a fountain with lighted flag poles and an outdoor seating area with lavish lawns, mature trees, and lighted walkways. A lobby renovation was completed at this tower in 2008.


In June 2007, the building was benchmarked and received an energy performance score of 74. Since this time, the management team has made energy efficiency a high priority for the tower and has successfully realized significant reductions across the board with gas, water, and electricity. Through zone and ducting repairs and energy management system (EMS) strategies that closely control our heating, gas usage has been reduced by over 50 percent. The water usage in the building has been reduced by 40 percent. The building has adopted more efficient landscaping practices such as improved controls and the installation of drip systems. All faucet aerators, urinals, shower heads, and toilets in the tower have all been replaced with water-efficient models.


Electrical usage has been cut by over 25 percent through measures including:
-- Completing fluorescent and LED lighting retrofits.
-- Making lighting adjustments in the garage.
-- Controlling lighting schedules more closely.
-- Installing occupancy sensors in all vacant suites.
-- Heating the indoor pool on off-peak hours to reduce demand charges.
-- Installing an economizer for the elevator machine room AC unit.
-- Installing variable frequency drives (VFDs) for the cooling tower fans and the condenser water pump.
-- Reducing heating supply fan energy, along with heating demand.
-- Redesigning the water fountain to use a pump one-third the original size.

Through constant efforts taken to improve the building's efficiency, 3945 Freedom Circle achieved an ENERGY STAR score of 78 in January of 2009, 88 in January 2010, and a score of 95 in January 2011.
