Monitoring and targeting

Energy monitoring and targeting techniques to help your organisation control and manage its energy use

Energy monitoring & targeting

The purpose of monitoring and targeting (M&T) is to relate your energy consumption data to the weather, production figures or other measures in such a way that you get a better understanding of how energy is being used. In particular, it will identify if there are signs of avoidable waste or other opportunities to reduce consumption.

Data collection may be manual, automated, or a mixture of the two. Once an M&T scheme has been set up, its routine operation should be neither time-consuming nor complex. An M&T scheme will provide essential underpinning for your energy management activities.

Monitoring and targeting guide

Monitoring and Targeting CTG077

This 31-page guide presents monitoring and targeting from two perspectives. One is routine use (on a weekly cycle, for example). Routine M&T as explained here is quick and simple and requires no particular expertise on the part of the user.

The other perspective is target-setting and diagnosis, an aspect that will appeal to users who wish to analyse data in more depth. Although this aspect needs to be addressed when first setting up an M&T scheme, it then becomes optional once the system is up and running.

M&T is an extensive topic and this guide can only provide an introduction to the more complex analysis methods and tools that can be used. Expert consultants can advise on more detail on applying these techniques within your organisation.
