Local Government Case Study – Fairfax County Jennifer L. Gorter, PE, CEM Fairfax County Government Facilities Management Department (FMD) July 11, 2008

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

Government Center Complex Energy Project Results

Results Total energy consumption

Results Consumption/gross SF

Historical Electric Costs

Historical Gas costs

Results Even when consumption decreases, expenditures continue increasing

Energy Benchmarking

Results Consumption and cost savings per year Total cost avoidance since 2001 exceeds $4 million

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

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
