NC-2009 EAc5: Measurement and Verification
Dear All,
We have a project installing a VAV air conditioning system with electrical reheat boxes in each zone.
The current design assigns energy submeters combining both the electrical reheat with the small equipment power.
My query is: do we need to monitor / submeter the electrical reheat separately, given that it is not as significant as the total heating consumption from the building boilers?
Thanks!

Is the gas consumption of stoves, ovens, etc. required under this point?
When should a project consider Option B instead of Option D?
Is there a requirement to model baseline energy use as being 25% process loads?
Does this credit specify how energy use should be measured?

You are actually not required to monitor or submeter anything by the IPMVP.
Can you accurately calibrate the model with the information you are currently gathering? Can you gather or derive the data another way, without a submeter? What is "not as significant"? If the energy use is very small for both the electric reheat and the small equipment power then you would need to justify that the usage is not significant (which you would define in your M&V Plan). Relative significance is not the issue, overall significance is the issue.
So you need to answer your own question. Do you need that data to calibrate your model?
