Energy Audit (10EE07)

  1. 1. ENERGY AUDITENERGY AUDITBy:Mahmood AliBy:Mahmood Ali(10EE07)(10EE07)
  3. 3. ENERGY AUDIT The verification, monitoring & analysis of use ofenergy including containing recommendation forimproving energy efficiency with cost benefitanalysis & an action plan to reduce energyconsumption. Energy audit is the key to systematic approachfor decision making in the area of energymanagement.
  4. 4.  It attempts to balance the total energy inputs withits use and serve to identify all the energy stream infacility. It quantifies energy usage according to its discretefunctions. Industrial energy audit is an effectivetool in defining and pursuing comprehensive energymanagement program.
  5. 5. NEED OF ENERGY AUDIT In any industry the three top operating expensiveare often found to be energy ( both electrical &thermal) labor & materials. If one were to relate to the manageability of the costor potential cost savings in each of the abovecomponents, energy would invariably emerges as thetop ranker, and thus energy management functionconstitutes a strategic area for cost reduction.
  6. 6.  Energy Audit will help to understand more aboutthe ways energy and fuel are used in any industry,and help in identifying the areas where waste canoccur and where scope for improvement exists. The Energy Audit would give a positive orientationto the energy cost reduction, preventivemaintenance and quality control programs whichare vital for production and utility activities. Suchan audit program will help to keep focus onvariations which occur in the energy costs,availability and reliability of supply of energy,decide on appropriate energy mix, identify energyconservation technologies, retrofit for energyconservation equipment etc..
  7. 7.  In general, Energy Audit is the translation ofconservation ideas into realities, by lendingtechnically feasible solutions with economic andother organizational considerations within aspecified time frame. The primary objective of Energy Audit is todetermine ways to reduce energy consumptionper unit of product output or to lower operatingcosts. Energy Audit provides a "benchmark"(Reference Point) for managing energy in theorganization and also provides the basis forplanning a more effective use of energythroughout the organization.
  8. 8. Types of auditInternal Audit:An audit of internal systems and/or procedures.An internal audit is most often performed bypeople how directly work for the company. Manycompanies hire outside firms (see third partybelow) to perform the audits.External Audit/Customer audits:Customer audits are those where a customer(or a customer representative) performs the audit.A customer audit is not objective because thecustomer is intimately involved with yourcompany (the supplier to the customer). Thisinvolvement can BIAS the audit.
  9. 9. Third Party AuditsThird party audits are like those you think ofwhen you think of bank audits. Banks (and otherfinancial institutions) must hire a company orperson to audit their books and procedures. Thecompany or person hired to do the audit cannothave an interest in the business it is auditing.This is known as an independent Audit. This isthe type of audit the registration audit is!
  10. 10. ENERGY AUDIT METHODOLOGYThe type of Energy Audit to be performed dependson:-Function and Type of Industry-Depth to which final audit is needed, and-Potential and magnitude of cost reduction desiredThus Energy Audit can be classified into thefollowing two types:1.Preliminary Audit2. Detailed Audit
  11. 11. Preliminary Energy Audit MethodologyPreliminary energy audit is a relatively quickexercise to:-Establish energy consumption in the organization-Estimate the scope of saving-Identify the most likely and the easiest areas forattention-Identify intimidate (especially no-/low-cost)improvements/ saving-Set a reference point-Identify areas for more detailed study/measurement-Preliminary energy audit uses existing, or easilyobtained data.
  12. 12. DETAILED ENERGY AUDIT METHODOLOGYA comprehensive audit provides a detailenergy project implementation plan for a facilitysince it evaluates all major energy usingsystems.This type of audit offers the mostaccurate estimate of energy saving and cost. Itconsider the interactive effects of all projects,accounts for the energy use of all majorequipment, and includes detailed energy savingcalculations and project cost.
  13. 13. - In a comprehensive audit, one of the keyelements is the energy balance. This is based onan inventory of energy using systems,assumptions of current operating conditions andcalculations of energy use. This estimated use inthan compared to utility bill charges.Detailed energy auditing is carried out in threephases:-Phase I: Pre Audit Phase-Phase II: Audit Phase-Phase III: Post Audit Phase.
