What a good audit report contains
Every report should include:
- The scope and boundary of the system audited
- The measurement plan: points, instruments, calibration and period
- The operating conditions during measurement
- Results presented with their limits and uncertainty
- Findings ranked by importance, with recommended actions
- Any assumptions made, stated clearly
Separate measured from estimated
Measured values, calculated values and estimates are labelled differently. A figure that was estimated is shown as an estimate, and is not reused later as though it were measured.
Evidence for savings
A saving is stated only when it rests on measurement or a documented model. The report shows the baseline, the expected change and how it will be confirmed. Savings from different actions are not simply added, because they overlap.
Verification after the work
After improvements are made, we recommend verification:
- Repeat the relevant measurements under comparable conditions
- Compare with the baseline
- Record what changed in the system and in the demand
- Report the result, including where it fell short of the estimate
Keeping records
The measurement data, the report and the verification are kept together so you can audit the audit. Changes to the plant afterwards are recorded so that later comparisons remain fair.
Start with
To arrange the work, please share:
- A simple layout or description of the compressor room, treatment and main piping
- Compressor and dryer details and operating pressure settings
- Operating hours, shift pattern and the problem you are seeing
- Any existing readings, trends or previous audit reports
Frequently asked questions
Do you guarantee savings?
No. Savings depend on the plant and on actions taken. We state expected ranges with assumptions and verify the actual result.
Why verify after the work?
It proves what worked and keeps the evidence for future decisions.
Can I keep the raw data?
Yes. The data and the method are part of what you receive, so the work can be checked.
