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…….
