share energy and water usage

I was also interested in this question and found for myself 2 answers: 1. from MPR supplemental guidance: "Metering and data collection for LEED-CS projects does not differ from other projects. Data may be collected from spaces that the LEED project team did not fit out as part of their core and shell design and construction – this is normal and acceptable." - "may be", not "must". 2. Since project must commit to share whole building data, water flow meter on the inlet from municipal source of water and from the electricity source must be enough. In case of "gray' water or on-site electricity generation - it's common to have meters at such sources.
