Energy Auditing and Measurement
- Collecting secondary data such as: drawing, single-line diagram, manuals, acceptance test reports, data log-sheet, etc.
- Identify the variables and measuring points
- Executing simultaneously on-line measurement by data acquisition systems
- Manual measurements for constant data and cross-check data for validations
Analysis, Evaluations, and Reporting
Data collected during the energy auditing and measurement are analyzed and evaluated to set up:
- The performance of every equipment or system
- Energy used every load
- Daily load curves and characteristic of every load
- Energy balance
