Our Office located in a group building of manufacturing was having one main meter that measures the total potable water. 

So, we don't have the permanent water meter for the Office. Thus, it is eligible if we would like to apply for LEED EBOM?

If we install the water meter for Office and start to record the data of consumption from now. For example, the data within 6 months since the meter will be installed, could we can submit for review? or must have one full year? Please advise on this matter.

Thank you in advance!
