The purpose of this step is to establish your energy use and trends in consumption. Ideally the past 3 years of energy bills would be used to establish these trends but a minimum of 2 years is required. One useful method is to develop annualised trends of energy use. You will also need to be aware of current energy sources and how much energy you expect to use in the coming period.
How to implement
In the EnMS Tool spreadsheet the worksheet ER1 Data provides an example of how to record energy consumption. The use of this worksheet involves adding energy bills on a monthly basis. These will include electricity, fuel and other sources identified during the energy review and included in the scope of your EnMS.
HINT: in Excel it is always best to insert data in columns and not in rows. For energy data maintain the data in continuous columns as in the template. Do not insert subtotals or other data into these columns.
Note that it may also be useful in managing water consumption. The techniques used in managing water use are very similar to those for energy management and very often it is the same people who are involved.
Additional columns may be needed in the ER1 Data worksheet, depending on your organization’s fuel sources. For example, many organisations use only electricity and natural gas as energy sources while others may have imported electricity, self-generated electricity or energy from a renewable source, oil, coal, waste as a fuel, purchased waste steam from a neighbouring plant and others. All sources need to be recorded in order to track them and also to consider alternatives.
The ER2 Trends worksheet can be used to monitor trends of consumption and costs based on the ER1 data. ER2 trends can also be used for budget purposes in helping to predict energy use for upcoming periods.
Careful examination of these simple trends based on your energy bills will reveal some questions which may help you to reduce your consumption?. It is important to track both the quantity of energy consumed and its cost. The energy bills should be added to the spreadsheet as soon as they are received and analysed as soon as possible after this.
Predicting future energy use and consumption - You need to be able to predict future use and consumption for a number of purposes including next year’s budget. By including this forecast in your bill analysis work you will always be able to see the trends in your energy consumption for each source.
If you have additional data, e.g. daily data for the energy sources or data for other large uses, you can follow the same process to monitor trends of consumption.
We highly recommend the annualised trending of consumption data for each energy source. This is achieved as a running total of the previous 12 months if monthly data or 365 days if daily data is used.
You also need to consider if there will be changes to energy use. This means checking if there are new or redundant uses, e.g. maybe steam will not be required in the future and what affect will this have.
