Hi.
Hope some can help.
In the LEED 2009 version you had to enter the energy consumption for the different measured systems from the Whole building simulation in ordre to see in the future if these values wass equal to the actual measured values. This was mostly to compare if the calculated energy consumption values (ventilation, lighting, etc.) = actual measured values.
In LEED v4, is it correctly understood that the Building-level metering and Advanced Metering have replaced the M&V plan for LEED v2009? And is there nowhere in LEED v4, where the actual energy consumption per meter have to be compared to the actual value measured?
Basically - if we have 1500 meters installed in the building - is it ever a requirement to find the energy consumption PR METER in the Whole building simulation in order to later compare it to the actual measured values during the Commissioning phase? And what if we "only" have the required LEED meters instlled - would we then have to extract the energy consumption per meter form the whole building simulation, or is it enough with have then grouped as the calculated energy consumption for Ventilation, lighting, pumps, PV cells, etc.?
Kindest regards, Lise

The credit was changed to focus on installing the infrastructure to enable comparisons post-occupancy but it is not required. I might suggest that if you don't do so you just wasted a fairly large amount of money and should not have installed the meters to begin with.

Hi Marcus - thanks for your quick response.
We will install and monitor all electrical, water and energy consuming equipment. The meters will be used for the ongoing operation and maintenance. My question was maybe a bit unclear - but it was mostly concerning the Whole Building Simulation. There is no requirements in LEED v4 to input ALL meters into the Whole Building Simulation, is there?
We will compare the simulation with the actual values measured, but on a larger scale, and not each and every singel meter (our client have a VERY large amount of meters) .

No you do not have to create a meter in the model for each meter in the building. If you would be doing calibration that would certainly help but it is not required. In your case with so many meters we would probably just do the calibration by end use for the most part.

Perfect - thank you. This was exactly how I have understood it - but had to be 100% sure.
