Facilities Management Department

• Facilities Management Department (FMD) is responsible for managing 170+ facilities

• Operate and maintain 8 million gross SF• Pay utilities for 6 million gross SF

Note: This does not include facilities operated by Parks, Schools, Housing or Public Works

FMD also manages annual utility costs of approximately $10 million (and rising!)

Energy Goal was established in FY2001 – to reduce energy consumption and energy costs

Where We Began

• Baseline usage established

• Installed Energy Management Control Systems (EMCS) in existing buildings

• Made EMCS standard for new buildings

• Review new building designs

• Cost management

• Picked “low hanging fruit” using ESCO

Completed Energy Projects

• Public Safety Complex Meter Totalization• Lighting retrofit in facilities

– T-12 lamps consume 40W each– T-8 lamps consume 32W each– Reduced 4 lamps to 3 per fixture for additional watts

reduction, overall light output remains the same

• Lighting and Variable Frequency Drive retrofit at the Government Center Complex

Results

• FMD’s Goal was 10% kBtu/SF reduction over 10 years (average 1%/ year)

• Between FY01-FY07, total kBtu/SF was reduced by 11.1%, which is 1.85% average reduction per year.

Where we are now

• Budget constraints = no funds for energy projects

• Past Capital Renewal budget requests have made primarily based on maintenance needs.

• Budget constraints = less funds for Capital Renewal

New Capital Renewal budget request priorities =

High energy user + High maintenance

Capital Renewal Combined with Energy Saving Strategies

John Marshall Library HVAC renovation resulted in 28.8% energy consumption savings

Before

After

The Good, the Bad and the Ugly

• The Ugly - Limited Resources means it will take longer to implement energy saving opportunities

»Money»Staffing»Time

• The Bad – no additional project resources for the next several years

• The Good - FY2009 budget establishes one full time staff position as Countywide Energy Coordinator

Where We Are Going

• Develop new reduction goals

• Prioritize projects to meet multiple needs and limited funding

• Other possibilities available– Evaluate renewable energy technologies– Demand side management– Work with code officials and engineers– Commissioning and Re-Commissioning
