Successful businesses are operated using financial systems, production systems, sales and marketing systems etc, however many of these companies do not have a structured Energy Efficiency Management System (EEMS) in place and this is detrimental from both a cost and sustainability perspective.

An EEMS is therefore a comprehensive process designed to measure, control, optimise and monitor energy usage. This is achieved through the development and implementation of energy efficiency work programmes, policies, operating instructions, awareness programmes and training.

Energy efficiency is much more then simply changing light bulbs and installing timers on air-conditioning units. Although these practices form part of energy saving initiatives they should be incorporated into an EEMS in order to achieve sustainable continuous improvement in energy efficiency efforts.

A structured Energy Efficiency Management System consists of the following steps;
- Energy Efficiency Assessment
- Gain support and commitment from management
- Communication and change management
- Develop Energy Efficiency Plan (EEP)
- Energy Efficiency Plan Implementation
- Energy efficiency monitoring and control


Energy Efficiency Assessment it is important that the baseline energy usage is established in order to determine the existing energy demand and usage pattern. This is done primary by the review of historical metered data. This assessment will also identify areas of energy saving opportunities.

Gain support and commitment from management this is critical to the success or failure of any energy efficiency effort. Management should uniformly support the programme and lead by example if the EEMS is to be a success.

Communication and change management the EEMS will bring about a vast change in mindset and attitudes towards energy and some resistance may be experienced from those who are not resilient. It is therefore important to create sufficient awareness around the programme with particular focus on its benefits.

Develop Energy Efficiency Plan (EEP) based on the investigation findings, this plan details the interventions required to achieve the energy efficiency goals. The plan includes work programmes, policies, operating instructions, awareness programmes and training and is task/duration based.

Energy Efficiency Plan Implementation during this section EEP tasks are executed according to plan and as per timelines and assigned budgets where necessary.

Energy efficiency monitoring and control this final step measures the overall effectiveness of the EEMS. Audits are conducted at predetermined intervals to ensure that the desired energy efficiency goals are being achieved and to determine whether further intervention is required.
