Services: Energy Management

An effective energy management programme is a prerequisite for achieving the efficient use of energy within any organisation. An energy survey will identify measures required to make savings and an energy management programme will achieve these savings. It is only by implementing the recommendations of an energy survey, along with monitoring & targeting and staff training, that maximised savings can be achieved. Experience suggests that the implementation of ad-hoc ideas on an informal basis can make some savings but many of the benefits to be gained are overlooked unless a structured energy management programme is introduced.

The key elements of an energy management programme comprise:

  • Energy Audit - a study to determine the quantity and cost of each form of energy to a building, process, piece of equipment or site over a given period.
  • Energy Survey - a technical investigation of the control and flow of energy in a building, process, piece of equipment or site with the aim of identifying cost effective energy saving measures
  • Monitoring and Targeting - the establishment of targets and subsequent monitoring of performance. M&T complexity should reflect the needs of individual organisations.
  • Training - key members of staff should be trained in good energy management techniques and all staff should be aware and motivated towards saving energy. Training is normally necessary to instigate successful energy management techniques and sustain savings achieved into the future.
  • Energy Policy Assessment, Design & Implementation - assess the current energy policy within an organisation to identify further requirements as appropriate


Carbon Twelve can provide your organisation with the advice necessary to develop a comprehensive Energy Management Programme tailored to your needs and requirements. Examples of previous clients are included at the lower end of this page.



Energy Audit:

Information is the key to improvement. An energy audit identifies when, when, how much and why energy is used. Data collected during an energy audit and the on-going collection of data in the future can be used with a well designed monitoring and targeting programme to identify areas of waste and to serve as a benchmark against which future energy savings can be compared.


Energy Survey:

A starting point for any energy management programme. The objective of a survey is to identify the current energy using plant provision and understand how and where resources are used. Recommendations for improvements that can be implemented to reduce energy consumption can be devised using the information gathered. Recommendations are identified in terms of "No Cost", "Low Cost" and "Higher Cost" measures to allow selection of the most appropriate energy management strategy. Further, Carbon Twelve provide general recommendations on the status of Energy Management and provide guidance for improvement as necessary.


Normally it is possible to identify energy improvement measures that will result in cost savings of between 5% and 20%. Occasionally, it is possible to identify higher savings. A survey generally covers the building, plant and processes. The investigation will normally consider the following items as appropriate:

  • HVAC - Heating, Ventilating and Air-Conditioning Installations
  • Building services controls
  • Industrial, assembly and manufacturing processes
  • Energy consumption and costs
  • Lighting
  • DHW - Domestic Hot Water
  • Cold Water
  • Building services and process controls
  • Energy Using Plant. e.g. steam generation, compressed air, chilled water
  • Refrigeration equipment
  • Combustion equipment efficiency using flue gas analyser
  • CHP - Combined Heat and Power
  • Staff motivation and awareness with respect to energy use
  • Staff training requirements
  • Current Energy Management policy and status
  • Monitoring and Targeting (M&T)

Carbon Twelve carry out combustion equipment efficiency tests using a portable flue gas analyser where possible. Where necessary, additional monitoring and sensing equipment is used during the survey to ascertain energy using plant operating status and environmental comfort provision.



Monitoring & Targeting:

Another essential element of good energy management. The use of established analysis techniques allows the identification of unnecessary waste and preferred areas for investment in efficient technologies and practices in the quest for a more efficient work-place.

Monitoring & Targeting can be carried out with varying levels of detail. The most basic form of monitoring is the use of performance indicators to compare energy consumption with benchmarks for the appropriate business sector. Where data is provided this is carried out as part of the energy survey. It is important to set targets for energy consumption and monitor actual consumption to ensure maximum efficiencies are achieved and continue to be achieved into the future.

Carbon Twelve can provide detailed advice on M&T or carry out the process on your behalf. Established analysis techniques that Carbon Twelve can provide assistance with include:

  • Degree Days
  • Normalised Performance Index
  • Specific Energy Consumption
  • Twelve Month Rolling Totals
  • Yearly / Monthly / Weekly / Daily / Hourly Analysis
  • CuSum Analysis
  • Specialist software packages are available to assist with monitoring and targeting. However, the dedicated software packages are normally uneconomic for all but large companies or organisations with multiple sites. It is normally more economic for smaller companies to develop M&T spreadsheets using, for example, Microsoft Excel. Carbon Twelve are able to provide advice and assistance in this respect.



    The training required during the implementation of an energy management programme has two key objectives: to raise the awareness of energy issues at all staff levels within the organisation and to provide essential technical and managerial training to the people who will deliver the benefits of the energy management programme. Training and awareness-raising should:

  • build greater understanding of the importance of energy efficiency and environmental protection, both locally and on a global scale
  • create a sense of ownership in the energy management programme and the results that it delivers
  • facilitate the dissemination of technical information
  • focus attention on the key issues.
  • Training programmes should cascade through the organisation, carrying the message that everyone needs to be involved in achieving energy efficiency. Training requirements vary greatly from organisation to organisation. The energy survey will identify the general needs. Carbon Twelve are able to offer training packages tailored to your company's individual needs.



    Energy Policy Assessment & Implementation:

    In order that an energy management programme works efficiently, both during its initial set-up and continuing into the future, the programme should be supported by an energy policy and action plan. A reporting structure is required and key members of staff should be delegated responsibility with the back-up of senior management. Carbon Twelve are able to compile energy policies and action plans based on your organisation's requirements.
