Understand. Evaluate. Improve.

A Clearer View of Your Energy Performance

Our assessment helps you understand where and how energy is consumed, identify significant energy users, evaluate equipment and system performance, detect avoidable losses, and develop practical energy conservation measures.

From Scope to Action

Our ISO 50002-Based Energy Audit Framework

The audit level, measurements and depth of analysis are agreed around your objectives, available information and facility conditions.

1

Preliminary Consultation and Audit Planning

  • Understand the facility, operations and client objectives
  • Define scope, boundaries and level of detail
  • Identify required documents, data and responsible personnel
  • Establish the schedule and measurement plan
2

Energy Data and Document Review

  • Review electricity bills, fuel records and consumption trends
  • Review production or operating data
  • Examine equipment lists, schedules and process information
  • Identify initial patterns and investigation priorities
3

Site Assessment and Walk-Through

  • Inspect major energy-consuming systems
  • Observe operating practices and equipment conditions
  • Discuss operational issues with relevant personnel
  • Identify visible losses, control issues and opportunities
4

Measurement and Data Collection

Depending on scope, measurements may cover electrical power and energy, current, voltage, power factor, load profile, flow, temperature, pressure, air velocity, equipment loading, operating hours and process parameters.

Methods, instruments and monitoring duration depend on the equipment, operating conditions and audit requirements.

5

Energy Performance Analysis

  • Develop an energy balance where applicable
  • Identify significant energy users and evaluate efficiency
  • Compare performance with design data, suitable references or accepted engineering practice
  • Analyse relevant operating variables, losses and inefficient conditions
6

Energy-Saving Opportunity Identification

  • Operational, control and maintenance optimisation
  • Equipment upgrades and waste-heat recovery
  • Reduced electrical, thermal or compressed-air losses
  • Better sizing, scheduling, loading, monitoring and management
7

Technical and Financial Evaluation

  • Estimated energy and cost savings
  • Implementation cost and simple payback, where data permits
  • Operational impact and technical feasibility
  • Priority, key assumptions and limitations
8

Audit Report and Management Presentation

  • Executive summary, facility profile and audit scope
  • Consumption profile, significant users and measurements
  • System performance, opportunities and financial indicators
  • Priorities, assumptions, limitations and follow-up actions

Findings may be presented to management or the client’s technical team.

Systems and Equipment We Assess

Coverage is tailored to the agreed audit scope; an audit does not automatically include every system listed below.

Electrical Distribution

Verify Actual Performance

Audit Measurement Support

Site measurements may be conducted where required to verify actual equipment and system performance. Measurement points, monitoring duration and instrument selection will be determined based on the system being assessed, site accessibility and the agreed audit scope.

Possible instruments

  • Power analyser
  • Clamp meter
  • Ultrasonic clamp-on flowmeter
  • Hot-wire anemometer
  • Infrared temperature gun
  • Other suitable instruments for the audit requirement

Documented for Decision-Making

Typical Deliverables

  • Energy-consumption review and energy-use breakdown
  • Significant energy-user identification
  • Site assessment findings
  • Measurement and performance analysis
  • Energy-saving opportunity register
  • Preliminary technical recommendations
  • Estimated energy and cost savings
  • Simple payback analysis where applicable
  • Prioritised implementation action plan
  • Management presentation or close-out discussion
  • Key assumptions, limitations and follow-up actions

Final deliverables depend on the agreed scope, data availability and level of audit.
