Introduction to energy audit part 1

920

Published on

This a compilation of the overall process in conducting energy audit based on my personal experiences, training that I attended in Malaysia, India and Japan and information sharing between fellow EE practitioners.Not to forget references from books and internet.
I believe this would benefit to those who wants to understand what is energy audit all about for beginners to become an energy auditor and to facilities owners to assess the need to conduct energy audit and energy audit proposals submitted by consultants

  5. 5. 5Definition• A very effective for energy management and improvement• To define and pursue comprehensive energy management programin the implementation of Energ Management System“A systematic approach to obtain the actualenergy supply and energy consumption dataand to identify measures to improveenergy efficiency level”
  6. 6. 6Pre Requirements For Energy Audit• A commitment from the top management to implementenergy saving measures Allocation of resources (auditor, budget) Availability of information and data (records) Energy audit equipment Allocation of time Hardware and software for data analysis• Previous and existing energy saving initiativesinformation and results• Regulatory compliance
  7. 7. 7What To Be Audited?Energy Management• Overall energy management system/practice• Efficiency of the facilities Supply and consumption• Energy lossFacts Finding On Item To Be Improved• General management items• Energy using equipment
  8. 8. 8Types Of Energy AuditPreliminary/Walk-through Audit•Walk-through•Simple measurements•No/low cost•Simple financial analysisDetailed /Investment Grade Energy Audit•Thorough data and site analysis•Complete measurements•More reliable energy saving potential estimation•ESMs with high capital investment•Detail financial analysis•Conceptual design of proposed measure•Involving financing and contractual documentsHIGHER SAVINGPOTENTIALS
  9. 9. 9Preliminary Energy Audit A relatively quick exercise to:Establish energy consumption in the organizationEstimate the scope for savingIdentify the most likely (and the easiest areas forattentionIdentify immediate (especially no-/low-cost)improvements/ saving measuresSet a reference pointIdentify areas for more detailed study/measurement Uses existing, or easily obtained data
  10. 10. 10Detailed/Investment Grade Energy Audit Provides a detailed energy project implementation plan and evaluates allmajor energy using systems Offers the most accurate estimate of energy savings and cost It considers the interactive effects of all projects, accounts for the energyuse of all major equipment, and includes detailed energy cost savingcalculations and project costs One of the key elements is the energy balance This is based on an inventory of energy using systems, assumptions of currentoperating conditions and calculations of energy use. Estimated use is then compared to utility bill charges. Can be carried out in three phases Phase I - Pre Audit Phase Phase II - Audit Phase Phase III - Post Audit Phase
  11. 11. Types Of Energy Audit : MAESCOLEVEL I LEVEL II LEVEL IIIWALK-THROUGH AUDIT STANDARD INVESTMENT GRADE Walk throughfamiliarization Desk top analysis Generate EnergyIntensity Recommend "no-cost" ESM Written Report withbroad conclusion Follow up from Level I audit whereavailable; a comprehensive audit A minimum 7 days logging &metering on major energyconsuming equipment of buildingservices or industrialequipment/systems Review system design, installation,operations and maintenance Detailing system energy inputs andenergy use Identify sources of inefficiency Compute BEI or Specific EnergyConsumption Index Generate load apportioning Provide Energy PerformanceIndicators Recommend "no-cost", "mediumcost" and "high cost" ESM Written report and presentation Inclusive of all scope of works of LevelI & II with the exception where onlyEA on specific systems are requested A minimum of 7 days logging andmetering on major energy consumingequipment of Building services orindustrial equipment/systems Detailed review of processes IAQ audit, if required Comfort study, if relevant Detailed recommendation oncomprehensive ESMs Detailed investment plan using NPVmethodology against life cycle Include Indoor Air Quality report toensure system is not affected (ifchiller audit) Written report and presentation 11
  12. 12. 12Who Can Perform Energy Audit?Internal Personnel• Energy Manager with the Energy Management Team• Employees working in the energy using process/equipmentAdvantages• Minimize time to familiar and understand the plant operationalconditions• Minimize costs• Easy access to information and data• Familiar with energy related issues, processes, equipment and company’slevel of expectations (targets, performance indicators, reporting and etc)Disadvantages• Limited allocation of time other than main duties• Limited expertise and knowledge in specific energy saving methods,analysis and technologies
  13. 13. 13Who Can Perform Energy Audit?External parties• External experts/consultants (if needed)Advantages• Can facilitate the Energy Management Team/EMWG• Energy management team can learn about new knowledge and technologies insaving energy• Minimum time to be spent by employees (focus to main duties)• Timeliness of the completion, reporting, preparation and presentation offindings in the energy audit report.Disadvantages• Generally very costly• Various level of supervisory and reporting (energy manager-auditor,management-auditor)• Difficult to predict the quality of audit ( no local accreditation for energyauditor)• Tendency to push for certain products instead of solutions to save energy

  16. 16. Basic questions to ask before deciding toconduct energy audit…1.Am I implementing energymanagement in my organization?2.Do it need energy audit? If yes,why?3.Would energy audit improve myenergy management?4.What type of energy audit thatI may require?5.What would I expect fromenergy audit at my facilities6.Would I implement findingsfrom energy audit?16
