Hello,

I am currently working on a project for which I am writing a M&V Plan implementing Option D of IPMVP. The current energy model shows 13 % cost saving (using typical ECMs) over the baseline (Based on ASHRAE 90.1-2007). recently the owner added a PV system to the building. this increases the cost savings to 49%.

How can I add PV system into my M&V plan (Option D)?

Do I need extra sub-meter for the PV system to directly measure the net energy output from the PV and subtract it from the whole-building Energy consumption?

Or Do I have to write a separate M&V Plan Option B for the PV system?

Thanks
