City of Charlottesville, Virginia

  • FY 2007-08 General Fund budget for utilities = $2.96 million
    • Schools = $1.15 million
    • Municipal buildings = 1.07 million
    • Street lighting = $.74 million
  • 2.2% of General Fund
  • Represents 6¢ of real estate tax rate
monitoring energy consumption
Monitoring Energy Consumption
  • First Priority – Establishment of YOUR baseline
  • What is your historical energy usage?
    • Every facility
    • Every utility account
    • Minimum 1 year data
baseline comparisons national
Baseline Comparisons - National
  • ICMA Center for Performance Measurement
  • Trade publications
  • EPA’s Energy Star Portfolio Manager - accounts for many variables, including:
    • Occupancy density
    • Size
    • Hours of operation
    • Climate
baseline comparisons regional
Baseline Comparisons - Regional
  • Establish network of others in your area
    • Share ideas
    • Share resources
    • Your region = your weather
  • ICMA Center for Performance Measurement, Virginia Performance Consortium
goal setting
Goal Setting
  • Energy Star Certification
  • LEED (new Buildings)
  • LEED-EB (existing buildings)
  • Short-term, long-term % reduction goal for entire building portfolio
  • Facility-specific goals
  • Environmental impact
key performance measures
Key Performance Measures
  • Annual – Portfolio vs. Individual Facilities
    • Cost per square foot
    • Kilowatt hours per square foot
    • Cubic feet natural gas per square foot
    • Thousand British Thermal Units (MBTUs) per square foot
      • Electricity – kilowatt hours x 3.142
      • Natural gas – cubic feet x 1.031
    • Tons of Carbon Dioxide per square foot
      • Electricity – (kilowatt hours x 1.285) / 2,000
      • Natural gas – (cubic feet x .120593) / 2,000
  • Major benefit – identifying opportunities
key performance measures1
Key Performance Measures
  • Monthly Analysis
  • kWh / Ft3 / MBTUs per square foot per day
    • Utility billing periods vary from month to month, even from account to account
    • Building A – current month versus last month, same month last year
    • Building A vs. average of all other buildings
  • Major Benefit – Identifying Problems
    • Seasonal? Building use? Leaks?
keys to improving performance
Keys to Improving Performance
  • Due diligence
    • Timely monthly analysis and review
    • Right people at the table = energy manager + maintenance staff
    • Effort – strive to devote as much time to this as utility budget = % of facilities budget
      • 50% budget = 50% of effort
    • Preventive maintenance
keys to improving performance1
Keys to Improving Performance
  • Ask questions –
    • What’s wrong?
    • Why?
    • What can we do about it?
  • Targeted investments
    • Dreaded “low hanging fruit”
    • Lowest performing buildings, largest buildings
energy manager s checklist1
Energy Manager’s Checklist

Infrastructure improvements

  • Planned equipment replacements more energy efficient
  • Building Automation System
  • Lighting upgrades
  • Energy Performance Contracts
infrastructure improvements
Infrastructure Improvements
  • Retro-commissioning HVAC systems
  • Energy Performance Contracting
    • Options for funding
    • Extension of staff
    • Large, fast impact
  • Capital investments include life cycle cost estimate, ROI, and in light of overall environmental goals

Building Occupant’s Checklist
discretionary energy consumption
“Discretionary”Energy Consumption
  • Building-Related Energy Consumption
    • ~ 60% Heating, Air Conditioning, Ventilation
    • ~ 40% Lighting, computers, etc.
  • Estimated energy used at discretion of occupants ~ 15%
bridging the gap
Bridging the Gap
  • How to turn Snidely Whiplash into Dudley Do-Right?
  • Snidely has his own mission
  • Snidely doesn’t care about your mission
  • Snidely doesn’t even know your mission
environmental sustainability program
Environmental Sustainability Program
  • Intent: Reduce consumption of electricity and natural gas, thereby reducing greenhouse gas emissions, and reduce consumption of water.
  • Goal of 10% net reduction, to be achieved through:
    • Thoughtful building use
    • Education and outreach
    • Infrastructure improvements
    • Incentive program
thoughtful building use
Thoughtful Building Use
  • Building Automation System
    • Scheduling standard operating hours for lights, HVAC
    • Special events scheduling
  • Building use recommendations – limit and/or consolidate after-hour and summer events to minimize energy footprint
education outreach
Education/Outreach
  • Monthly meetings with principals/designees to review energy trends, identify savings opportunities
  • Sample lesson plans to relate energy/environmental issues to curriculum
  • “Everyone” emails, with monthly energy savings tips, updates
  • School Board updates
  • Presence at Quarterly “Principals Meetings”
incentive program
Incentive Program
  • Quarterly budgets goals established for utility consumption for each school
    • Based on historical seasonal and consumption trends
    • Normalized for fairness to $1.20 per square foot for 12 months
incentive program1
Incentive Program
  • Monthly Most-Efficient School Award
    • Trophy 
    • Lunch for staff
    • Competition fierce!
first year results
First-Year Results
