Energy Audit

WHAT IS ENERGY AUDIT? 

1. OBJECTIVES OF ENERGY AUDIT

– Evaluate current situation of energy consumption at factories/buildings

– Identify and analyze energy saving measures to meet the Law on Energy Saving and Efficiency as well as reducing cost, including:

• Do detailed assessment for each potential area and identify energy saving potentials
• Assess feasibility about technology
• Analyze cost and benefit

– Suggest execution of energy saving measures

– Develop detailed energy audit report in line with regulation of the Circular 25/2020/TT-BCT

– Support enterprises in completing report on annual energy consumption and 5-year plan on energy saving and efficiency submitted to local Department of Industry and Trade required by the Law

– Support in instruction of preparing energy management form for intensive energy users as required by the Law.

2. WHAT ARE BENEFITS OF ENERGY AUDIT FOR ENTERPRISES?

– Well know about current situation of energy consumption at factories/buildings as well as identify unusual energy consumption of equipment/system;

– Have evidences to evaluate energy saving potential and setting up overall vision/trend on energy and cost

– REDUCE OPERATING COST by executing energy saving measures as mentioned in energy audit report

– Comply to the Law on Energy Saving and Efficiency (MOIT), with the energy audit report completed by official consultant (as required by the MOIT) submitted to local Department of Industry and Trade

3. HOW TO EXECUTE ENERGY AUDIT?

– Off-site survey for initial data collection on operation of factories/buildings as well as current situation at recent times (by questionnaire)

– On-site assessment:

• Operation of utilities, including energy management procedure
• Problems of equipment
• Issue and requirement for users’ comfort
• Equipment stability
• Expected equipment demand
• Specific plan for using machines and equipment
• Improve existing equipment and plan for the future

– Check main utilities/systems, install specialized measuring equipment to collect energy consumption data of factory/building within a certain period of time to assess and confirm the suitability of the operation of systems.

– Systems proposed for assessment:

• Power system
• Lighting system
• Motor, pump, fan
• Compressed air
• Thermal system, boiler  and oil-fired furnace
• Water supply and waste water treatment system
• Energy management system
• Production process
• Others (if any), etc.

– Deliverables:

• After detailed survey, the collected data will be calculated, analyze and then energy saving measures appropriate to energy consumption status of factories/buildings will be suggested by audit teams
• After finalizing proposed measures, the detailed energy audit report will be completed as required by the MOIT
• The energy audit report will be in Vietnamese version, depending on each enterprise’s requirement, the report will be translated into English for reference.

4. EXECUTION TIMELINE OF ENERGY AUDIT

– On-site assessment (at factories/buildings), 3 – 5 days on average depending on each scale, current situation of energy consumption and special fields

– Report completing: 04 weeks (from the first day of on-site survey)

– In case of upgrade audit, such as investment project (on energy saving measures/technologies/energy efficiency), the on-site assessment and report completing will be longer than usual. At that time, ENERTEAM and enterprises will finalize suitable timeline and be flexible in each related activity performed.
