What is Energy Audit?

Energy audit is a regular review of the usage of energy in a building to increase effectiveness of energy. The auditors examines the energy account of energy consuming equipment, checks the way energy is used in its various components and identifies savings opportunities. An energy audit process typically includes:

  • Analysis and assessment of your system/equipment’s energy performance
  • Identification of “Energy Management Opportunities (EMOs)”
  • Potential saving estimates
  • Recommendations for energy savings solutions

Benefits from Energy Audit:

Energy Audit is an effective energy management tool. By identifying and implementing the means to achieve energy efficiency and conservation, not only can energy savings be achieved, but also equipment/system services life can be extended. All these mean savings in money. Based on the principle of “The less energy is consumed, the less fossil fuels will be burnt”, the power supply companies will generate relatively less pollutants and by-products. Therefore, all parties concerned contribute to conserve the environment and to enhance sustainable development

   ENERGY AUDIT=SAVINGS IN MONEY+ENVIRONMENTAL PROTECTION+SUSTAINABLE DEVELOPMENT

Typical Procedure to Conduct Energy Audit

  1. Defining scope of energy audit (Walk through audit is suitable for organization with limited resource and detailed audit is suitable for organization with more resources)
  2. Forming an energy audit team. (The team shall include management representatives, maintenance professionals & staff representatives etc)
  3. Estimate time frame & budget (auditor-hours, whether any disruption to the occupants, and the cost of measuring instruments etc)
  4. Collecting building information (Floor area, building orientation, equipment design condition, energy bills and system schematic diagrams etc)
  5. Conducting site inspection & measurement to identify means for improvement
  6. Analysing data collected
  7. Recommending the improvement actions and measures

Flow Chart on Conducting Energy Audit:

Framing the energy audit report:

The report should outline the objectives and scope of audit, description of characteristics and operational conditions of equipment/systems audited, findings in the audit, EMOs identified, corresponding savings and implementing costs, recommendations on EMO implementation and programme and any other follow-up actions.

Upon completion of all EMOs identified in an energy audit, a minimum energy saving of 5%-10% could be achieved for a typical commercial building.
