5 Energy Auditing Process There’s more to an audit than field work!Pre-FieldField WorkPost FieldDraft ReportFinal report
6 Energy Auditing Process – Data Gather Information – site plans, one line drawings, historical utility information, operating logs, SOP’sVerify – meter and account numbers, rate classAnalyze – kwhrs, peak demand, voltage, thermsPUI Power Usage Index – Benchmark data center to comparable facilities in the region.Carbon Use – determining equivalent tons of CO2
7 Energy Auditing Process Key StepsEstablish a Baseline from an energy point of viewData Gathering and AnalysisField WorkWhat did we find?Post Field AnalysisCan we optimize existing equipment?Should we invest new capital?Draft Report for client commentsFinal report
8 Energy Auditing – Pre Field Work Conference call – prior to beginning field workDiscuss known problemsUnderstand special site considerationsDetermine benchmark kwhr and therm rateConfirm initial impressions based on data receivedEstablish field scheduleEstablish client resources: client personnel, HVAC or Controls contractor if neededClient 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 personnelObserve operationsInspect and gather name plate and measured data on chillers, cooling towers, CRAC units, lighting, controls, pumping systems and other major energy consuming equipmentUse portable data loggers where appropriate
10 Energy Auditing – Post Field Work Evaluate findingsResearch opportunitiesPerform energy calculationsDetermine ECO’s and their Greenhouse Gas reduction potentialPrepare draft report summarizing ECO’s and their estimated paybacks.
11 Energy Auditing – Draft Report Standard report is in PowerPoint formatNYSERDA format if neededIncludes our ideas and opportunities to reduce energy use and costIncludes an ECO’s table and executive summaries explaining each ECOCalculates estimated paybacksIs sent to the client (and NYSERDA) for review, comment and input
12 Energy Auditing – Final Report Incorporates Draft Report comments and input from the clientIncludes our field notes and calculationsIncludes final calculationsPresentation of our findings is normally in personBound hard copiesElectronic version
13 Energy Auditing – Potential ECOs Controls setpoint modification - temperature and humidityChilled water flow optimizationAir flow modificationsAir leakage reductionsEconomizer operation (free cooling)Variable speed drives on pumps/chillers/towerLighting fixture modificationsLighting controls
14 Energy Auditing – Potential Incentives Incentives vary by state……NJ – prescriptive and holistic (Pay for Performance)NY – NYSERDA$$ for energy studiesHolistic savings, cents per kwhr reducedCT – Low % loans, prescriptive, RCx, per utilityPA - prescriptive, Act 129, per utilityMA – prescriptive, per utilityThey even vary by utility…….
