5Energy Auditing Process
- Theres more to an audit than field work!
- Pre-Field
- Field Work
- Post Field
- Draft Report
- Final report
6Energy 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
7Energy 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
8Energy 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
9Energy 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
10Energy 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.
11Energy 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
12Energy 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
13Energy 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
14Energy 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.
