Fault detection and root cause analysis of big data provide a strategic approach to energy savings at high-performance healthcare, pharmaceutical, and university laboratory buildings. Insidious HVAC faults are often superseded by reactive maintenance. By analyzing building data, large scale operational issues can be mitigated and persistent alarms can be minimized. The economic impact associated with these issues can be used to quantify building performance improvement potential.

BMS data from a 1.2 million square foot healthcare facility will be used to highlight the procedure for fault detection and data analysis. The examples provided will focus on air handlers and laboratory ventilation equipment; however, the techniques involved will be readily applicable to zone devices and plant equipment. This presentation will discuss typical high-value controls, mechanical, and operational faults. Using aggregated facility data, we will explore fault identification, root cause analysis, and issue remediation. The presentation team will then focus on quantifying the energy savings that result from the appropriate corrective actions. Lastly, we will cover the impact of data quality and reliability on our outcomes.

Through the examples provided, this presentation will demonstrate how a methodical approach to BMS analysis, programming, and design can result in high-functioning, energy efficient lab building operation.

Learning Objectives

  • Understand how to evaluate big building management data as a tool for identifying faults.
  • Understand how control strategy optimization can counter reactive maintenance.
  • Identify the economic and environmental benefits of big data analysis.
  • Recognize and appreciate high-value data points and reliable data collection.

Meet our presenters:

Lisa Zagura has over 10 years of engineering experience in building automation and mechanical systems. Her work at Cimetrics involves energy analysis, providing implementation recommendations, and Analytika reporting for over 30 buildings in the healthcare and pharmaceutical industries. Prior to joining Cimetrics, Lisa was the manager of the New England automation design team at Siemens, where she was responsible for managing control system project design. Lisa received her M.S. from Boston University.

Julianne Rhoads, Cimetrics

Julianne Rhoads joined Cimetrics in 2017 and is responsible for energy analysis and reporting on more than 35 buildings, including over 4 million square feet of facilities in the higher education, healthcare, and pharmaceutical research sectors throughout the United States. She has identified and helped to implement more than $2 million in annual energy savings.

Prior to joining Cimetrics, Ms. Rhoads was responsible for designing Energy Performance Contracting projects at Siemens Industry, Inc.
