WHY?
If your business is wasting energy it is causing avoidable
pollution, primarily through increased carbon emissions leading to climate change, whilst contributing to the problems associated with dwindling fossil fuel reserves.
But wasting energy also reduces your profitability. For every £1 saved
on energy costs, most UK businesses would have to make £10 worth of sales to make the
same £1 of profit. So, for example, wasting just £1,000 a year on energy due to poor energy management would require £10,000 worth of sales to make the equivalent
£1,000 of profit.
The Government’s support programmes on energy efficiency and carbon management have proved that most companies can reduce their energy costs by at least 10%
through the implementation of simple housekeeping measures and by as much as 30% through the implementation of cost-effective measures.
Monitoring & Targeting (M&T) provides the means to
identify where energy is used, where it is wasted and where to have the most effect in
implementing energy savings measures. This guide includes a special quick start guide to energy M&T to help explain how this simple but effective management tool works.
By implementing the 'Low Carbon Hierarchy' (see right-hand side of this page) in all investment decisions, your organisation can make the most cost-effective progress towards a more sustainable future for its energy needs.
THE 5 STEPS TO EFFECTIVE ENERGY MANAGEMENT
Step 1. Commitment
Make it your company’s policy to use
energy efficiently and to keep carbon dioxide emissions to a minimum wherever possible. A simple statement of policy objectives – perhaps as part of your
environmental policy – will show senior management’s commitment to energy
efficiency and helping to reduce or negate the organisation's contribution to climate change. Once this has been decided, it is important that someone
should be the ‘energy champion’ in your organisation. This person should have
the support of top management and be given the necessary resources to be effective.
The energy champion should: act as the firm's eyes and ears for
energy wastage; be responsible for reading the meters and
checking the fuel bills; develop a weekly or monthly checklist of
duties; and consider forming an Energy Action Team to
report on progress and problems to stimulate further action.
Remember: The key factors for success in energy management, as in any other management
discipline, are:
• pressure for change (senior management commitment is essential)
• a clear shared vision (you must take staff with you)
• capacity for change (provide the resources: time & finance)
• action (monitor performance & keep your communication channels open)
The 5 steps in this guide should help you achieve that success. For further guidance on changing the culture of your organisation, see the highly popular Managing Change Guide on this website (www.oursouthwest.com).
| "There are numerous examples in the South West where energy managers (or champions) in companies have made significant energy savings through changing staff attitudes and good housekeeping. Making a corporate commitment to energy efficiency led to 15% energy cost savings for a Gloucestershire based company." |

Back to the top Move to Step 2 THE 5 STEPS TO EFFECTIVE ENERGY MANAGEMENT
The maxim "You can't manage what you don't measure" is especially true for
energy management. Invoices alone will not provide sufficient information for you to take
full control over your energy costs. You need to take your own meter readings at regular
and frequent intervals. This will enable you to:
Meter readings can be recorded on worksheets
or on a computer spreadsheet. In either case consumption can then be displayed
graphically, which is useful for detecting trends and giving warning of exceptional
consumption. The relatively high cost of transport fuel
means that if you have a transport fleet, a high proportion of your overall energy costs
will be diesel or petrol. Each vehicle should have a record of activity and service log.
This should record date, mileometer reading, fuel purchased, cost, driver and service
details. This data can be used to analyse vehicle performance and overall costs.
Step 2. Understand
(establish the facts)
- identify exceptional consumption and attend to the causes quickly;
- check utility invoices and ensure that you pay only for the fuel actually used;
- compare current costs and performance with previous years;
- compare several sites, processes or buildings in the company with each other;
- compare your performance against typical standards for similar businesses; and
- assess the seasonal pattern of consumption.
Making these comparisons will help you set
improvement targets and identify where the greatest scope for saving energy exists in your
business.
The Carbon Trust has published a wide range of Energy Consumption Guides. These can be obtained from the
Carbon Trust's website (www.carbontrust.co.uk) or
by telephoning the Carbon Trust on 0800 085 2005.
How often you take meter readings will be
determined by how much energy is used. As a general rule of thumb, meters should be read
monthly if invoicing is quarterly and be read weekly if invoicing is monthly. IMPORTANT
– Readings should be made at the same time of day and day of the week, particularly
if the reading is weekly.
| "A Swindon organisation looking at energy management for the first time was shown how to apply Monitoring & Targeting (M&T) techniques to its energy use at its headquarters building. The result was a 26% saving on energy costs – and this was without any capital investment." |
One way to
reduce energy costs is to buy your fuel at the lowest price. Shop around for the best
deal. For electricity, there are several ways of paying less for each unit of electricity,
for example:
- make maximum use of cheaper units, especially night-time units
- minimise use of peak rate winter units
- reduce peak demand where possible
- check the tariffs to ensure you are paying the minimum amount for availability and for your maximum demand against your agreed availability
- check with your supplier that your load has no unusual characteristics, such as low power factor.
If your maximum demand for electricity is greater than 100kW you should be able to negotiate a contract with a supplier. If it is less
than 100kW you will probably be on a standard tariff but there is a wide range of tariff structures - discuss the options with your supplier.
Consider looking at fuels or energy sources
that can reduce your liability to pay the Climate Change Levy - renewable energy sources
and, where sufficient heat demand exists, Combined Heat and Power [Note: You are advised
to take professional advice to ensure your business would benefit from such changes].
THE 5 STEPS TO EFFECTIVE ENERGY MANAGEMENT
Step 3. Plan and organise
The energy policy statement (step 1) can be used to raise staff awareness and demonstrate the commitment of senior management. In a small business this may be the proprietor. A simple policy statement should set out the main objectives, together with the performance targets that need to be met to fulfil the objectives.
Once objectives and targets have been agreed,
action plans can be drawn up to drive the management plan forward and set down what needs
to be done and when. Your action plan should:
- have management approval
- relate actions to particular objectives
- assign actions to individuals
- allocate resources (both time and money if needed) to each improvement
Use promotional material, internal newsletters and staff meetings to raise staff awareness. Although
you may make one indvidual responsible for energy efficiency, the involvement and commitment of all staff is
crucial to achieve success. All staff should be encouraged to participate. Incentive schemes (benefiting facilities for staff
or perhaps a local charity chosen by staff themselves) can help ensure that actions are taken and that all staff
contribute to energy efficiency measures. The Managing Change Guide on
this website (www.oursouthwest.com) can help you embed the policy at all levels in your organisation.
THE 5 STEPS TO EFFECTIVE ENERGY MANAGEMENT
Step 4. Act
A good way of finding
energy waste initially is to conduct an energy walk-round. Ask key members of staff
to accompany you – both to identify problems and opportunities, and to ensure they
feel part of the assessment process.
The pattern of energy use will vary throughout
the day, so it is useful to vary the times that you carry out your walk-rounds, for
example:
- when the cleaners are on duty
- at lunchtime
- at night or over weekends (if your
meter readings indicate that there is
unexpectedly high energy use during these periods).
Note where energy is being wasted because of
lack of awareness, or procedures are being ignored, repair or maintenance work is needed
to reduce energy costs, or there is a need for capital investment.
To help you with the walk-round you might like to use an example walk-round checklist: click here to down load the checklist in word: checklist
This checklist has been taken from the "Better Business Guide to Energy Saving" publication (reference GPG 367) from The Carbon Trust. It is highly recommended that you obtain a copy of this
useful guide that also includes practical advice on heating, lighting, office equipment, electrical equipment, refrigeration, compressed air etc. You can download the guide from the The Carbon Trust's website or by telephoning the
Carbon Trust on 0800 085 2005. There are also many useful case studies and good practice guides available from this programme that can give specific technical or management advice to help you.

bill is substantial and you need advice on a particular aspect of your energy use, free
expert help is available via the telephone or, where appropriate, site specific
advice can be provided at your site from The Carbon Trust Tel: 0800 085 2005.
THE 5 STEPS TO EFFECTIVE ENERGY MANAGEMENT
Step 5. Control, monitor & review
Energy management should be a process of continuous control and improvement, not a one-off effort. You must therefore set up recording and monitoring systems to both check that targets are being met and to identify further cost reduction opportunities offering attractive returns on investment.
Use meter readings (Step 2) to monitor progress and compare results with your own targets and performance indicators.
In the UK, the process of continuous recording and monitoring of energy use against consumption targets is known as Monitoring and Targeting (M&T) and has been shown to be an effective management tool in numerous companies and organisations BUT it should be kept up. Experience has shown that once companies stop monitoring their energy use on a regular basis, waste starts to occur – often at least 10% in a relatively short time. This is because problems arise (for example failed or wrongly set controls) and procedures change and the effect on energy consumption goes unnoticed or unexplained. See "Quick Start Guide to Energy M&T" (pdf, 544kb) - this includes information on how to use CUSUM as a powerful technique for energy management.
Do use the data you are collecting! "One Swindon organisation was already recording energy data but was not analysing the data produced. 16% energy wastage had already occurred over 7 months. Once shown how to analyse the data, potential wastage of 28% per annum was avoided! The cause of this waste was a maintenance contractor that had changed the control settings to the building’s heating system during a routine visit but had not reset the settings. Simply looking at the monitoring data and comparing with previous months’ data identified the problem." |
The Carbon Trust provides useful good practice guides on energy M&T. These can be obtained from the Carbon Trust's website (www.carbontrust.co.uk) or by telephoning the Carbon Trust on 0800 085 2005.
aM&T
aM&T is a management system that automatically collects energy consumption data and analyses this data to ensure energy use is in line with targets set by the user. aM&T includes the
meters, automatic data collection, database collation, analysis and presentation. aM&T automatically delivers useable energy management information to the person(s) who can make changes.
Most aM&T systems allow the user to set targets for energy use and review current performance against these targets. Many systems automatically produce variation reports and notify users of potential problems by e-mail or text message.
Today many systems are web based and can be extended to cover consumption of other utilities in addition to the traditional electricity and gas use e.g. water, fuel oil, steam etc. Typically the application of aM&T can lead to savings of c.5% although often even greater savings can be enjoyed on individual
sites. Many users are instantly surprised at the level of avoidable energy waste that they identify.

If you have successfully completed all 5 steps (but don't forget the "Quick Start Guide to Energy Monitoring & Targeting") (pdf, 544kb) you should now be making significant energy savings - and also helping to protect the environment.
To maintain these savings on a continuous basis go back to Step 2 and review each step.

The Low Carbon Hierarchy - the route to a low carbon, climate friendly economy
The most cost-effective solution for reducing your carbon footprint is to:
1. REDUCE energy use by avoiding unnecessary use and implementing energy efficiency measures. You should include the design of your goods and services and also look up and down your supply chain.
Once you have increased your efficiency you should then look to
2. REPLACE fossil fuels with renewable energy sources and/or use cleaner fossil fuel technology such as Combined Heat and Power (CHP) where it is
feasible to do so.
Finally, having reduced your carbon emissions through avoiding waste, energy efficiency and use of renewable cleaner sources, you can
3. NEUTRALISE the remaining unavoidable emissions through carbon offsetting schemes.
