Option 2. Monitoring-based Commissioning
Monitoring-based (MBCx) commissioning enables building operators to identify operational issues as they occur, facilitating the achievement of the project’s performance goals on an ongoing basis.
Both Paths 1 and 2 require the following:
-
Energy Information System (EIS) that enables visualization, analytics, and automated reporting of energy data
-
Monitoring and automatic transmission of data to the EIS for energy use under the building owner’s or facilities manager’s control. Include hourly electricity use and monthly use for each nonelectric source supplied to the project.
-
Training for facilities staff empowering them to leverage the EIS to review trends, identify anomalies, perform preventative and predictive maintenance, and identify opportunities to decrease energy consumption and greenhouse gas (GHG) emissions. Provide retraining if initial training occurred more than six years before the start of the reporting period.
-
Development and implementation of an MBCx plan extending at least three years past the end of the 12-month reporting period. Include the plan in IPp4: Current Facilities Requirements and O+M Plan . By the end of the 12-month reporting period, the project team must initiate corrective action to address identified anomalies and complete at least one MBCx summary report.
PATH 2. ENHANCED MBCX
In addition to meeting the requirements for Path 1, Path 2 requires projects to provide enhanced MBCx practices and software capabilities.
MBCx provider Contract with a third-party MBCx Provider (MBCxP) or designate a qualified MBCxP on the building operations team. The MBCxP must have direct experience with similar projects. Many MBCxP providers have a programming or controls integration background and extensive experience with EIS and Fault Detection and Diagnostics (FDD) technologies. The MBCx plan and contract or corporate program must include the required level of communication and reporting between the MBCxP and the facilities staff referenced in the Rating System. Fault Detection and Diagnostics (FDD) for Projects with Large HVAC or Refrigeration Capacity FDD Software is only required for project scope with a total capacity of equipment exceeding any of the following values:
- Cooling . 7,200 kBtu/h (600 tons or 2110 kW)
