I recieved a comment for a project of mine and dont really know what they want exactly. They need a "description of quality assurance procedures".
Quality assurance of what exactly?
Is it verification of metering accuracy or does it have to do with the actual equipment performance?
If it is related to equipment performance, what performance? (ex. efficiencies of pumps, chillers, and cooling towers?)
Must we have implemented algorithms in the BMS programming to calculate pump, chiller, and cooling tower efficiency in real time?

The quality of your calibration and verification. Think of it as quality control measures. How will you know that you produced accurate results?
Metering accuracy should be noted in the M&V Plan.
In order to properly calibrate the model you should also be checking the modeling assumption for equipment efficiency against what was installed. Depending on the situation you may need to develop a custom curve for the equipment if you suspect that the curve used in the model may not be accurate.
The essential issue is to know what the model needs to be calibrated within the level of accuracy cited in your Plan.
