Energy Audit

What is Energy Audit?

Energy audit is a systematic analysis of energy use and energy consumption within a defined energy audit scope, in order to identify, quantify and report on the opportunities for improved energy performance.

Type of Energy Audit

Level 1 - Walk Through Energy Audit : Quick review and assessment of energy performance of the plant or building. Preliminary information on areas where energy performance can be improved.

Level 2 – Preliminary Energy Audit : Provide a preliminary assessment of energy usage and potential energy saving by identifying the opportunities. These audits take a relatively short time and the results are more general, providing common opportunities for energy efficiency. 

Level 3 – Detailed Audit : Provide a detailed measurement and analysis of equipment performance. The result of the audits are more comprehensive and useful since we provide more accurate picture of the energy performance of the plant and more specific recommendations for improvement. 

Assessment Scope of Energy Audit

Energy Management Culture : Review the Energy Management System and Energy Consumption Profile. Discussion with the energy manager and energy team. 

Power Quality : Access the electrical system to determine the quality of the electrical system (power consumption, cos phi, unbalance voltage, unbalance current, frequency, harmonics). Measurement will be conducted by trending method and sampling method.

Equipment Performance : Access the equipments of facilities to determine the performance of the equipments (water pump, electric motor, air compressor, HVAC system, and lighting system). 

Measuring Instruments Used : The measuring equipments used while audit are high of accuracy and calibrated.

ELECTRICITY USAGE

Assessment and online measurement on electricity consumption pattern and power quality.

AIR COOLING & LIGHTING SYSTEM

AIR COOLING SYSTEM - Air cooling systems require a lot of energy. Assessment and measurement on air conditioning system will be conducted to know the COP (coefficient of performance).

LIGHTING SYSTEM - Assessment on lighting intensity and compare with the applicable standard will determine the effectiveness of the lighting usage and comply with the regulation.

SUPPORTING UTILITY

Most of SEU (Significant Energy user) in a building or industrial comes from supporting utility (electric motor, compressed air, boiler, pump system, etc). Assessment on supporting utility will measure the utility performance to and the opportunities to improve the performance and energy savings.
