Metering and Submetering

I concur that the nomenclature is confusing. For Case 1, "submetering" essentially means metering of the main energy sources in the tenant space e.g. electricity, natural gas, hot water, chilled water, etc. (Note that with the exception of process, electrical end-uses can be combined into a single meter.) More technically speaking, this is "submetering" relative to the main building meters. In the context of Case 2, "submetering" is the metering of the individual energy uses - notwithstanding that the credit language above calls this "metering", which is arguably incorrect.

Sorry Gordon, but did I get you right. In a Case 2 project I allways have to meter electricity for Lighting, Plug Loads, Heating, Cooling, etc. separatly. A combiened meter for "all" the electricity consumed by the tenant is not sufficient. Thanks!
