Standard Operating Procedure for Energy Audit

Procedure:
Pre-Auditing Phase

1. The Auditor shall propose and presented about energy audit to the client.
2. As the client agreed to be having energy audit on his/her building, the client
shall give an appointment letter to the auditor as a sign of approval to audit the
building.
3. Auditor shall be doing a pre-auditing site visit. The purpose of this visit is for
the auditor to get an overview of the building that will be audited.
4. From the finding or information obtained from the pre-auditing site visit.
Auditor shall create and proposed a Gantt Chart for the energy auditing.
5. Auditor shall be forming an auditing team that will performing the auditing
processes. The measuring equipment and personal protective equipment (PPE)
that will be used during the auditing process will be listed and prepared. The list
of equipment that will be used by the auditor will be presented in Appendix A
6. Kick off meeting between Auditor and the client will be held. In the meeting,
the auditor shall present to the client the auditor team, the Gantt Chart, and the
job scope of auditing process.
Data Collection Phase

7. Desktop Data Collection. client shall provide required data needed by the
Auditor to be used in the audit process. The data provided by the client is:

 Architectural Drawing
 Building Electrical Drawing
 Building Mechanical Drawing
 Historical TNB Bills

8. Based on the data and information obtained from the client, the auditor shall
review and recheck will the proposed Gantt Chart. If there are any additional
task needed to be done, Auditor shall adjust the schedule prior to the information
provided.
9. Auditor shall do a site investigation to verify the data obtained. If any new
information obtained from the visit, the Gantt chart will be updated.
10. Field data collection: the auditor shall carry out necessary data measurements
required to establish daily load patterns, major equipment loadings, chiller and
Air Handling Unit (AHU) parameters and others.
11. The data that need to be collected during the field data collection is:
 Main Switch Board (MSB) logging.
 Room Data Survey.
 Equipment List.
 Distribution Board (DB) instant clamping.
Standard Operating Procedure for Energy Audit

 Chiller Logging.
 Chiller flowmeter logging
 AHU Data Collection.
The data collection form will be presented in Appendix B

12. For MSB logging, the auditor shall install a power logger at building main
switch board (MSB) in two weeks’ time based on SEDA guidelines for MSB
logging process. This process is to monitor the power consumption of the
building and to obtain the load pattern.
13. For room data survey data collection, auditor shall collect the data on lux level,
room temperature, Carbon Dioxide (CO2) concentration and Air Humidity in
the working spaces or area.
14. Auditor shall collect and list on all the active electrical equipment including its
quantity, power rating and its usage hour.
15. For Distribution Board (DB) instant clamping, the auditor shall measure the
instant reading of voltage and ampere on the distribution board. This is to
compare the value of the summation of the total distribution board (DB) with
the sub-switch board (SSB) and main switch board (MSB).
16. For Chiller logging, auditor will install power logger on the chiller distribution
board to monitor the power consumption to generate the chiller and to measure
the efficiency of the chiller.
17. Auditor shall install flowmeter on the chiller pipe specifically on chill water
pipe. The purpose is to monitor the performance of chiller motor pump and the
to monitor the efficiency of the chiller.
18. For air handling unit (AHU) data collection, the auditor shall collect these
following data:
i. The size of the ducting.
ii. The speed of the air flow in the ducting.
iii. The temperature in the ducting.
iv. Air Humidity in the ducting.
v. Concentration of carbon dioxide (CO2)
vi. Instant ampere value of the AHU motor.
19. As the auditor completed the data collection, the auditor shall proceed to the
analysis phase.
Analysis Phase

20. After all the data’s and findings were collected and obtained from both desktop
data and field data collection, it shall be compiled and documented by the
auditor.
21. The data’s will be tabulated in table using Microsoft Excel application and from
the table it will be presented in graph and pie chart form.
Standard Operating Procedure for Energy Audit

22. Analysis shall be made from information obtained from the pattern of the graph
and the pie chart.
23. A suitable Energy Saving Measures (ESM) shall be proposed by the auditor
based on the result obtained from the analysis.
Report Phase

24. In this phase, all the data’s including the analysis, proposed EMS will be
compiled in a report.
25. A draft report will be prepared by the auditor consisting all the information
regarding the energy audit done on the proposed building.
26. The draft of the report later will be presented to the client. The purpose of this
presentation is to inform the client about the result of the auditing process and
to propose the energy saving measurement to the client.
27. The feedback from the draft report presentation shall be considered by the
auditor and the improvement shall be done in the report.
28. The improved draft report will be sent to and reviewed by the client.
29. As the client satisfied with the improved draft report, the auditor shall proceed
to complete the final report.
30. The final report shall be hard bounded and signed by both auditor and the
client.
31. Final report is submitted to the client, SEDA and a copy of the report will be
kept by the auditor.
