Energy Performance & Efficiency Auditing

Service summary

An evidence-based review of energy consumption, significant uses and existing efficiency measures. The assessment examines the quality of energy information and the operating factors affecting reported performance.

The service helps management understand where conclusions are well supported and where further technical investigation is needed. It does not guarantee savings or provide engineering design and investment decisions unless separately agreed.

Key objectives

• Evaluate energy data reliability
• Examine significant-use operating practices
• Assess reported efficiency performance
• Identify unsupported performance assumptions

Methodology

A defined energy review combines consumption analysis, operating observations and examination of existing efficiency measures against agreed technical criteria.

• Agree energy boundaries, review depth, period and required expertise.
• Collect energy records, operating data and measurement information.
• Identify significant uses and select representative operating conditions.
• Observe relevant controls and examine metering or calibration evidence.
• Analyse consumption patterns and the basis of reported improvements.
• Evaluate data gaps, operating variation and measurement limitations.
• Report qualified performance findings and areas needing further investigation.
