Do you have any sample of Measurement and Verifiation report for Option B?
Thank you and cheers!

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?

Option B would very rarely apply to a new construction project. Any project claiming energy savings for improvements in building envelope or lighting cannot use it as these are interactive measures (they affect other systems). I have reviewed thousands of projects submitted for LEED and have not seen one successfully use Option B. Unless you are that extremely rare case use Option D.

Marcus,
Thank you for your helpful and immediate answer. I am not familiar with this credit, we had never attempted it before. I don't know how complex or simple it might be, is there a way you could provide us with a sample of an approved format for the submittal of this credit? It sounds, by reading the IPMVP guidelines that it would be a very short document (about 2 or 3 pages). I don't know if I'm getting it right.
Any thoughts?

You will need to prepare a M&V Plan. A sample plan outline is in the Documentation Toolkit above. A reasonable M&V Plan is typically a minimum of 8 to 10 pages, not included appendices.
The Plan content depends on the approach to data gathering which needs to be thought through and very detailed. Most of the rest is pretty straight forward from there. Make sure to thoroughly read the IPMVP. I find many folks do not really understand it and this is evident in their M&V Plans. It is about verifying predicted savings. So gather the data necessary, post-occupancy, to verify the energy modeling inputs, calibrate the model to the actual bills and then create a calibrated baseline. The difference is your actual savings. Be sure to include an action plan in the event your savings do not agree with your prediction.
