Submeters may not be linked to billing, but identifying the consumption related to individual buildings is important. Even if a meter is not used for billing, regular readings, taken manually if necessary, should be incorporated as part of the monitoring strategy. Electricity bills will also show maximum demand charges (see Chapter 8), and further analysis should reveal whether loadshifting is feasible as a means of reducing these charges. A series of bills going back a number of years will also enable long-term trends in energy usage to be revealed.
