1. Building Management System Analytics and Diagnostics Can Aid Facility Staff, If Properly Programmed


Today's tip from Building Operating Management comes from Rita Tatum, contributing editor for the magazine: New building management and energy management system have analytics and diagnostics capabilities can save time for facility staff, but they need to be properly programmed.

In the past, facility managers often had operating staff who could tell or sense when a building system was faltering and knew instinctively what needed to be done to fix it. However, these seasoned facility engineers are now retiring.

"People entering facilities management don't have that real-world experience," says Jim Sinopoli, managing principal, Smart Buildings. "And there's more technology in today's buildings. BAS/EMS today needs more analytics software tools to support the new generation of facility engineers."

Those tools are often designed to make it easy to learn to use them. "The prevalence of easy-to-use Web-based interfaces, email alarm notifications, pre-made report forms and basic fault diagnostics can enable the typical overworked building manager to do more with less," says Robert G. Knight, senior associate with Environmental Systems Design. "That building manager no longer needs weeks of specialized off-site software training, or a degree in mechanical engineering, to keep a building running comfortably and efficiently."

Nevertheless, new building management and energy management systems are built on advanced software. To use that software optimally can be a challenge for traditional building operators. In response, Knight is encountering more customers who are adding in-house systems integration capabilities. That capability may come from the corporate IT department, from a systems integrator on the facility management team, or from the energy manager.

"The honest truth about all this powerful software," says Knight, "is that it still can't do the thinking for us. Somebody needs to write and tweak the fault diagnostic algorithms, model new energy management scenarios in the analytics software, refresh the content on the LEED kiosk, modify the management dashboard when the CIO wants a new metric."

Analytics, Fault Detection Improve Building Automation Capabilities

Today's tip from Building Operating Management comes from Rita Tatum, contributing editor: Today, detailed analytics and fault detection systems are starting to offer the potential for improving the performance of building automation systems.

New technology starting to be deployed today offers the ability to predict when something is going wrong, before systems stop working altogether. "The BAS operator can't just keep his or her eye on the chiller and big air handling units anymore," says Robert G. Knight, senior associate with Environmental Systems Design. "Now, the facility manager's got fountain pumps and pool chemical controllers and kitchen grease precipitators, all revealing their every inner parameter to the network. So analytics are really becoming necessary to filter through that noise and help direct the operator's attention to the problem."

The diagnostics come in many capabilities and price ranges. One software application for HVAC systems uses fault-detection diagnostics (FDD). The National Institute of Standards and Technology (NIST) developed FDD some years ago. The software evaluates equipment relationships, such as the chiller's connection to the air handler and the air handler's reliance on variable air volume devices, to diagnose a problem in performance. Using predictive analytics rules, the software analyzes and identifies faults or conditions where HVAC is not running optimally and alerts the BAS/EMS front end station.

"Some of this software really takes on not only DDCs but also systems normally considered outside BAS/EMS monitoring," says Jim Sinopoli, managing principal, Smart Buildings. "These systems are handling exterior shading, interior blinds and even seismic monitoring."

Analytics and fault detection and diagnostics capabilities are sometimes being offered within BAS/EMS applications themselves, and sometimes they are separate applications from companies that don't make BAS/EMS.
