NC-v4 EAc1:Enhanced commissioning

Eligibility of EMS for MBCx

Hallo,

Does anyone know if an EMS (Energy Management System) that is composed of energy meters to measure and track energy makes a project eligible to pursue Monitoring Based Commissioning? 

I'm wondering if a project that will NOT have in place a BMS/BAS to control or monitor the building's mechanical and electrical equipment such as ventilation, lighting, fire systems or security systems can achieve this credit.

Thanks for your help,

Good question and I do not have a good answer. You have the right start, having some detail in energy use that can be compared to the energy model and commissioned state. I assume the building has smaller unitary systems so a BMS is not really required. Monitoring Based Commissioning is not well defined, and it is not just about having data...you need to have a plan to address how the data is used to maintain and improve building performance. I could see a methodology that would use the data on energy use along with actual weather data and energy model that could then be used to confirm that the building is operating in the commissioned state...but it would be more manual effort than a solution that has the processing power of a BMS.
