3.2 Acquire and analyse energy data
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.
3.1 Identify legal and other requirements
Many organisations have externally imposed requirements concerning their energy use. These will include local and national laws and corporate or customer requirements. In order to manage your energy effectively you need to be aware of these requirements and to ensure that you comply with them.
