I read the IPMVP Vol 1 on option C, as our project is 75% more than the total building area.
i not too sure what i read is correctly, therefore need more clarification.
base on this option, we need to install submetering at major energy consumption load (lighting, hvac system, irrigation, etc). once we installed these metering, do we need to have a BAS to monitor it?
as i read along the IPMVP book,. at clause (4.9.5 Option C: Metering), it mention that ,we could track our usage base on utilities bill as we need to do the actual payment every months. this method could allow us to track our usage as compare with the baseline as well.
am i correct?

Hi Tristan and Christopher, can help to comment about my doubt?
do we need to installing a BAS as to comply to Case 2?

As I mentioned in a previous reply/string above, Option C is not an appropriate approach in most cases and arguably should not have been included in the credit language. Regardless, the submetering systems must have some means of collecting and collating data into a useable form. This can be through the BAS or a standalone system. Utility bills can be used as a component of the metering system (provided that the bills can be aligned with the submetering data), but I suggest that this is an awkward approach.
