Chula Vista Cancer Center
Description of Facility and Operations
Chula Vista Cancer Center is a 40,858 quare foot, three-floor medical office building (MOB) located at 751 Medical Center Ct., Chula Vista, CA 91911. The building was built in 2012. The first floor and half of the second floor are used by Sharp, while the third floor and remainder of the second floor are leased space for medical offices and maintained by Kidder-Matthews.
Despite the building operating roughly 70 hours a week on a 8:00a – 5:00p Monday to Friday schedule, the Sharp spaces are served by a rooftop chilled water air handler unit (AHU) with 4-fan supply and return fan walls that runs 24/7. A 90-ton chiller is located on the roof and a cooling tower is in an enclosure in the parking lot. Two boilers on the roof operate in a lead/standby configuration to supply heating hot water to the variable air volume (VAV) zones. The remainder of the building spaces are served by a number of smaller heat pumps split systems. Interior lighting is in the process of being changed to LEDs, while the exterior lighting was installed as entirely LED in 2012.
- Chula Vista Cancer Center spends $3.98/sq. ft. for utilties.
- The building's energy use per square foot is 17% lower than the national median energy use intensity for medical office buildings.
• Replacing the split systems with a second rooftop air-handler unit (AHU) is highly recommended to allow better efficiency and better centralized control of the mechanical system.
• Make-up water and blowdown water from cooling tower are not metered; install meters and pursue sewer charge credit for drift and evaporative losses. Est. cost per meter = $500 - $1,500.
