NC-v4 EAp1: Fundamental commissioning and verification
With the removal of the M&V credit under LEED V4.0, is a calibrated energy model still required under Fundamental Commissioning and Verification credit or some other LEED credit?

For a building with individual systems per unit, does every single system need to be commissioned?
What kinds of projects must the CxA demonstrate experience on?
What level of authority does the CxA have towards correcting inaccurate or erroneous construction?
Can the CxA be a member of the design or construction team?

MKK,
With eliminating the M&V credit, V4 is moving toward Monitoring-based Commissioning (EAc1, Option 1, Path 2) and Advanced Energy Metering (EAc3) as a means to monitor and verify energy performance during building occupancy. Neither of these credits, nor the Fundamental Commissioning and Verification prerequisite (EAp1) will require a calibrated energy model.

Paul is correct, M&V as it was known in v2009 no long exists, but in its place are a series of three credits that provide the foundation for robust measurement and tracking of energy use. Involving the CxA in design of the on-going monitoring systems is a great step, as during the process they see the kinds of trends that are needed to ensure proper operation of the systems. I always called these key parameters, and worked with the owners and integrators to make sure if these parameters were changed, over-ridden, or went outside certain bounds, that some notification went to the management for investigation.
