Building Data

The value that Infometrics delivers is primarily derived from data collected from sensors and actuators that are connected to building control systems and building mechanical equipment. When combined with system and equipment set points, the data can tell us a great deal about how well the building control system is performing and where the problems are, including issues that can’t be detected through simple equipment observation.

There is a vast amount of data available in a large building—if you were to read one sensor every 15 minutes, you would have 35,000 data samples after one year. Most large buildings have thousands of sensors and actuators, resulting in tens of millions of data samples per year! Special tools and expertise are needed to collect, manage and analyze all of this information. It is not surprising that most facility maintenance departments do very little effective analysis of building control system data.

Cimetrics has invested many man-years of effort into understanding how to extract valuable information from building data. Our Infometrics analysts review each facility’s points list and building system documentation to determine what data we should collect. In some cases we may recommend that the customer add specific sensors to the building control system so that we can provide the maximum possible benefit.
