Monitoring and Commissioning of Existing Buildings

The objective of this project is to assemble and develop a set of manual tools, test procedures, and guides to support the commissioning of heating, ventilation, and air conditioning (HVAC); lighting; and other building systems. This work has produced diagnostic procedures and commissioning tools that will help owners, operators, and the commissioning industry test and operate buildings more efficiently than has been possible in the past.

Tasks:

Fault Detection and Diagnosis Tools and Techniques
The objective of this task is to evaluate current diagnostic procedures and tools that can be used by building practitioners to determine when the performance of building systems has degraded to the point that the cost in terms of efficiency or comfort merits replacement or repair.
Guide to use Energy Management Control Systems (EMCSs) for Monitoring
The objective of this task is to develop a procedure for assessing the economic viability of using older EMCS systems for monitoring, including criteria for using an EMCS "as is," upgrading it, or installing a separate monitoring system.
High-Information-Content Electrical Load Monitoring
The objective of this task is to develop and deploy high-speed electrical load monitoring that can provide component-specific load information from a centralized location (motor-control center, HVAC service entrance, or whole building), thereby substantially reducing the cost of obtaining this information.
Develop Occupant Feedback Methods for Diagnostic Systems
The objective of this task is to incorporate occupant feedback into building system diagnostics so that the efficiency and effectiveness of building operations can be improved.
Commissioning Persistence Investigation
The objective of this task is to investigate the reasons that the performance of mechanical systems, including system retrofits, degrade over time and to recommend intervals at which testing should be performed. Further objectives are to assess the relative costs and benefits of continuous monitoring and periodic testing.
