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

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.
