A comprehensive and structured approach based on the ISO 50001 framework that is used to improve energy consumption, efficiency and performance.

Implementation will lead to reductions in emissions and energy costs. Is applicable to all types and sizes of organisations, irrespective of geographical, cultural or social conditions.

The EnMS journey is based on the: PLAN - DO - CHECK - ACT (PDCA) continual improvement framework and strategically incorporates energy management into everyday organisational practices.

Conduct energy review to establish current energy scenario. Draft action plans to improve energy performance in accordance with the organisation’s energy policy.

Technical Management HR Supply Chain Financial Maintenance

• Draft an energy policy• Identify legal and other requirements• Set objectives and targets• Collect and analyse data• Identify SEU’s• Establish baseline, energy drivers and EnPI’s• Identify savings opportunities • Draft action plan• Design measurement plan

• Provide corporate commitment

• Provide resources (human,financial)

• Set and approve targets

• Assign roles and responsibilities

(as part of KPI’s)

Commitment to comply with all applicable legal and corporate requirements related to

energy management

Commitment to drive continual improvement in energy performance

Commitment to ensure the availability of information and resources to meet objectives

and targets

Consideration of energy efficiency in the purchase and .design of products, services,

process and plant improvements

Documented, communicated and understood within the organisation

Name and signature of top management

• Determine critical operating parameters and maintenance criteria

• Insert energy performance requirements in procurement conditions and design policies

• Implement savings opportunities• Document• Meter

• Provide training and awareness raising resources

• Encourage feedback and check progress

• Communicate changes• Ensure competence and

awareness of employees• Instill trust and promote

buy-in

BEWARE BARRIERS • No dissemination of information by management • Lack of resources (training, technical) • Production focus overshadows competence • No feedback on progress

AWARENESS: All employees and contractors are made aware of the company’s commitment to improve energy performance.

COMPETENCE: All staff affecting energy performance have the necessary skills and expertise to carry out their tasks efficiently.

TRAINING: All employees working with SEU’s are trained on operating procedures and how they impact on energy performance.

Monitor and measure energy performance against energy targets and objectives, and report the results

• Review system performance

• Update documentation• Review potential

opportunities

• Take corrective action• Ensure continuous improvement • Ensure documentation review• Ensure regular system audits • Schedule, report progress and secure support at

regular management reviews• Use outputs to find solutions and make decisions

BEWARE BARRIERS • Top management is not committed and pays lip service to energy management.

• Evaluate legal compliance• Ensure measuring instruments are calibrated• Review EnPI’s and analyse variances• Conduct internal audits and identify

non-conformities• Implement preventive and corrective action• Check energy performance improvement

• Participate in internal audit process

• Ensure all non-conformities are addressed

REGRESSION ANALYSIS Scatter plot and trendline that is used to accurately predict the relationship between energy usage (Y-axis) and the selected process variable (X-axis). This technique is considered best practice for establishing elevant variables, EnPI’s and forecasting energy usage. Also used in M&V to account for variations in site activity and adjusted baseloads. Best fit line: y=mx+c

A CUSUM PLOT(Cumulative SUM of Savings) is a powerful graphical technique which illustrates cumulative net savings from inception of the programme to the present date.

BEWARE BARRIERS • Internal audit team unfamiliar with audit protocols • Key actions not documented

Some EnMS Definitions:- Nonconformity - Non-fulfilment of a requirement- Correction - Action to eliminate a detected nonconformity- Corrective action - Action to eliminate the cause of a detected nonconformity- Preventive action - Action to eliminate the cause of potential nonconformity
