Case Study

California Institution for Women |Chino, California

Energy Efficiency Survey

Situation:

Located in the cities of Chino and Corona California, the facility is a 120-acre prison that receives and houses female inmates at all custody levels. The facility consists of a series of buildings used for housing, education, laundry, medical services, and administration. Through a partnership program between the California Department of Corrections and Rehabilitation and the Investor-Owned Utility Partnership program, it was determined that energy- efficiency measures needed to be identified and analyzed to determine how cost savings in this area could be maximized.

Solution:

After the Utility contacted Lincus with this challenge, the engineers completed an energy survey at the facility. From this detailed study, variousenergy-efficiency measures (EEMs) were identified and recommended as follows:

• Replace existing air-cooled roof-top package units with more efficient, higher SEER units
• Install programmable thermostats to control the temperature during unoccupied periods
• Retrofit existing fluorescent lightning with magnetic ballasts with high-efficiency fluorescent lighting with electronic ballasts
• Replace high-pressure sodium fixtures with high-efficiency two-lamp T5 Fixtures
• Retrofit existing incandescent exit signs with LED signs Install occupancy sensors in offices and support rooms

The cumulative payback for all EEMs is estimated to be 4.3 years. with an annual electricity savings of 144,235 kWh. These measures provide the customer with more than $16,000 in annual utility savings.
