5
Energy Auditing Process
  • Theres more to an audit than field work!
  • Pre-Field
  • Field Work
  • Post Field
  • Draft Report
  • Final report

6
Energy Auditing Process Data
  • Gather Information site plans, one line
    drawings, historical utility information,
    operating logs, SOPs
  • Verify meter and account numbers, rate class
  • Analyze kwhrs, peak demand, voltage, therms
  • PUI Power Usage Index Benchmark data center to
    comparable facilities in the region.
  • Carbon Use determining equivalent tons of CO2

7
Energy Auditing Process
  • Key Steps
  • Establish a Baseline from an energy point of view
  • Data Gathering and Analysis
  • Field Work
  • What did we find?
  • Post Field Analysis
  • Can we optimize existing equipment?
  • Should we invest new capital?
  • Draft Report for client comments
  • Final report

8
Energy Auditing Pre Field Work
  • Conference call prior to beginning field work
  • Discuss known problems
  • Understand special site considerations
  • Determine benchmark kwhr and therm rate
  • Confirm initial impressions based on data
    received
  • Establish field schedule
  • Establish client resources client personnel,
    HVAC or Controls contractor if needed
  • Client financial hurdles

9
Energy Auditing Field Work
  • Each team member is a degreed engineer with
    extensive field experience in energy plant
    operations.
  • Interview site operations personnel
  • Observe operations
  • Inspect and gather name plate and measured data
    on chillers, cooling towers, CRAC units,
    lighting, controls, pumping systems and other
    major energy consuming equipment
  • Use portable data loggers where appropriate

10
Energy Auditing Post Field Work
  • Evaluate findings
  • Research opportunities
  • Perform energy calculations
  • Determine ECOs and their Greenhouse Gas
    reduction potential
  • Prepare draft report summarizing ECOs and their
    estimated paybacks.

11
Energy Auditing Draft Report
  • Standard report is in PowerPoint format
  • NYSERDA format if needed
  • Includes our ideas and opportunities to reduce
    energy use and cost
  • Includes an ECOs table and executive summaries
    explaining each ECO
  • Calculates estimated paybacks
  • Is sent to the client (and NYSERDA) for review,
    comment and input

12
Energy Auditing Final Report
  • Incorporates Draft Report comments and input from
    the client
  • Includes our field notes and calculations
  • Includes final calculations
  • Presentation of our findings is normally in
    person
  • Bound hard copies
  • Electronic version

13
Energy Auditing Potential ECOs
  • Controls setpoint modification - temperature and
    humidity
  • Chilled water flow optimization
  • Air flow modifications
  • Air leakage reductions
  • Economizer operation (free cooling)
  • Variable speed drives on pumps/chillers/tower
  • Lighting fixture modifications
  • Lighting controls

14
Energy Auditing Potential Incentives
  • Incentives vary by state
  • NJ prescriptive and holistic (Pay for
    Performance)
  • NY NYSERDA
  • for energy studies
  • Holistic savings, cents per kwhr reduced
  • CT Low loans, prescriptive, RCx, per utility
  • PA - prescriptive, Act 129, per utility
  • MA prescriptive, per utility
  • They even vary by utility.
