Metering and Monitoring

Hello everyone:I have just started to working in a project of energy efficiency in buildings and I always see references to a monitoring proyect and metering proyect separately but in my opinion these two are the same thing, you need a metering project to have points with measures, and we need measures to develop in the next step (monitoring project) to work about these measures to obtain more information like efficiency improvement, energy performance, ect. I don´t know if there are another difference between this two. On the other hand I need a guidelines of metering and monitoring. If someone could help me I would appreciate.Thanks you very much and regards.
