Targeting techniques rely on three main principles, which form a constant feedback cycle, therefore improving control of energy use. Monitoring Monitoring information of energy use, in order to establish a basis for energy management and explain deviations from an established pattern. Its primary goal is to maintain said pattern, by providing all the necessary data on energy consumption, as well as certain driving factors, as identified during preliminary investigation (production, weather, etc.) Reporting The final principle is the one which enables ongoing control of energy use, achievement of targets and verification of savings: reports must be issued to the appropriate managers. This in turn allows decision-making and actions to be taken in order to achieve the targets, as well as confirmation or denial that the targets have been reached. Procedures Before the M&T measures themselves are implemented, a few preparatory steps are necessary. First of all, key energy consumers on the site must be identified. Generally, most of the energy consumption is concentrated in a small number of processes, like heating, or certain machinery. This normally requires a certain survey of the building and the equipment to estimate their energy consumption level. It is also necessary to assess what other measurements will be required to analyze the consumption appropriately. This data will be used to chart against the energy consumption: these are underlying factors which influence the consumption, often production (for industry processes) or exterior temperature (for heating processes), but may include many other variables. Once all variables to be measured have been established, and the necessary meters installed, it is possible to initiate the M&T procedures. Measure The first step is to compile the data from the different meters. Low-cost energy feedback displays have become available. The frequency at which the data is compiled varies according to the desired reporting interval, but can go once every 30 seconds to once every 15 minutes. Some measurements can be taken directly from the meters, others must be calculated. These different measurements are often called streams or channels. Driving factors such as production or degree days also constitute streams and must be collected at intervals to match. Define the base-line The data compiled must then be plotted on a graph in order to define the general consumption base-line. Consumption rates are plotted in a scatter plot against production or any other variable previously identified, and the best fit line is identified. This
