What is the difference between Submetering and allocation?
Advances in metering technology have made it possible to economically convert master-metered properties to individually Submetered units. However, in some properties it is not possible to install Submeters. In those properties, it may be possible to allocate utility usage to each consumer based on factors such as the size of the unit, number of occupants, or number of bathrooms. A commonly-used term in the industry to describe utility allocations is RUBS, which stands for Ratio Utility Billing System.
