My customer will build a new K-12 school building using LEED V4. We are in the planning stages and they have expressed interest in monitoring-based Cx. However, they are under the impression it will add roughly $200,000 to the construction budget (that works out to almost $2 per square foot). That concerns them; so they have asked me to find out what is really required to accomplish this. I have researched the LEED V4 BD+C Reference Guide, ASHRAE 0, ASHRAE 1, LEED User, and various reports, presentations, white papers on the subject... I have yet to find my answers. Perhaps the template on the new LEED-On-Line V4 answers my questions, but I have not been given a link yet to see this credit (so I don't know).
Please don't mis-judge me, I actually like monitoring-based Cx, and think it is a great benefit for a building owner and believe it will likely save as much or more energy long term than just about any other ECM out there (in fact, I would lobby it’s worth more than 1 pt) - but I have to think like the owner and CM here because they will make the here goes.....

Metering? - It is not clear that we have to add any meters beyond the main electrical service meter, main gas service meter and main domestic water service meter - all of which normally come from the utility company (yes?/no?)

Systems? - I would say it seems obvious that we will have to cover lighting, chiller, boiler, domestic water; but is it necessary that we cover fans? pumps? the electric terminal heaters at entry vestibules? etc.... In other words, is not entirely clear "how far down we have to drill" (?)

Electricity KW vs Kwh? - There is a separate credit for participating in demand control programs offered by the local utility, thus, I am assuming electricity in monitoring-based Cx can be captured in Kwh only - i.e., monitoring usage, not demand (yes?)

Frequency? - It does not seem to be made clear whether monitoring must be done on any particular increment - every 15 minutes? every hour? once per day? - What is the required frequency? Are different trends expected to be monitored at different frequencies (example: lighting every hour, but boiler every 15 minutes)?

My feeling is that teams will be “very torqued” if they invest a lot of thought, time, programming, cost for sensors, costs for meters, etc - then submit to GBCI only to get a bunch of comments back from the reviewer inferring that their MBCx isn't enough. Might it be possible to have the reviewer do a pre-review of just the MBCx plan first?

Thank you
