The 12 Things You Need to Know about Monitoring-Based Commissioning (MBCx)

From the moment a building is constructed and starts consuming resources, it starts deteriorating. Mechanical, electrical, automation, and all building systems naturally decline over time in terms of both performance and efficiency. The results can be the same; operations and maintenance costs rise, energy consumption rises, and occupant comfort may decline.
Building owners and managers know they have options to prevent this natural progression, but are often overwhelmed by a glut of contradicting information, misinformation, and misconceptions in the marketplace. Different vendors use different terms like commissioning, existing building commissioning, fault detection and diagnostics, smart buildings . . . the list is nearly endless.
Although the terms are different, the message is the same: “Let us analyze and optimize your building and we’ll save you money.” It’s certainly an attractive proposition—spend a little money now, save a lot of money later. But because of the terminology confusion, abundance of market options, and lack of standardization in approaches to dealing with this issue, building owners and managers have become understandably leery of sales pitches. In the midst of the confusion, though, lies a truth; what the industry calls continuous or monitoring-based commissioning does, in fact, deliver improved building performance and energy efficiency.
Defining Monitoring Based Commissioning
According to a report by the Lawrence-Berkeley National Laboratory, “Monitoring based commissioning (MBCx) combines ongoing building energy system monitoring with standard retro-commissioning (RCx) practices with the aim of providing substantial, persistent, energy savings*.” What we are really talking about is a sophisticated package of software applications that combines building data from a wide variety of sources to better manage building performance and efficiency. MBCx involves the implementation of improvement measures along with ongoing service and insights necessary for full transparency, measurement, and reporting. That is, what facility engineers have done manually for decades can now be completed more efficiently, more comprehensively, and more accurately by combining building and energy system data with an engineering team’s expertise through the MBCx process.
When MBCx is built into a continuous building improvement process, it allows combined technologies involved in data mining to identify faults or issues in building systems with the necessary human analysis to determine how to address those faults or issues. Truly advanced MBCx solutions will also help identify and prioritize resolution paths; for example, if there is simultaneous heating and cooling in air handler 5, facility engineers should investigate a leaking chilled water valve to avoid a potential costly expenditure.
Defining MBCx is the first step toward understanding it.
Successful MBCx Delivers Value
As the Lawrence-Berkeley National Laboratory report confirmed, MBCx does deliver energy savings and a return on investment, but the real long-term value of commissioning is in the building performance improvements and compliance efforts. That value, however, is only possible through a comprehensive combination of the right people, processes, and technologies to continuously optimize a building’s performance and efficiency.

UPCOMING REALCOMM WEBINARS
REAL ESTATE INFORMATION ANALYTICS – Harnessing the Power of the Data - 2/7/2019
It started with spreadsheets and pivot tables, moved to databases, then to data warehouses, onto analytics and business intelligence. Now, analytics often refers to machine learning and artificial intelligence. In the end it is simply about collecting and maintaining accurate comprehensive data and applying some form of sophisticated analysis to gain insight and make better decisions. Combining internal and external data can provide organizations with a better understanding of individual assets, portfolios and markets. This webinar will gather the industries’ most experienced professionals who will discuss how data disruption and leveraging data will allow you to better position yourself for significant growth. Product options, data strategies, personnel requirements and more will be addressed.
