5. Energy Auditing Process
There’s 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, SOP’s
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 ECO’s and their Greenhouse Gas reduction potential
Prepare draft report summarizing ECO’s 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 ECO’s 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…….
