THE 5 STEPS TO EFFECTIVE ENERGY MANAGEMENT
Step 2. Understand
(establish the facts)
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:
- 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.
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.
