City of St. Louis

A Smart Solution for City-wide Integration


The city of St. Louis, Missouri faced two major challenges when looking to upgrade the buildings that housed the city’s top officials.

The first was the severe climate that St. Louis faces throughout the year. Temperatures have been known to fluctuate double digits within a single day. The winters are brutally cold, with many days never getting out of the single digits. The summer months are equally harsh with extended periods often reaching over 100 degrees, coupled with high humidity. Comfort is hard to come by, but was much needed for the officials who ran the city.

The second was taking old and often failing systems individually installed in each building, and replacing them with a dependable, central system; encompassing ten buildings and thousands of points. The new building automation system also had to be durable enough to survive the harsh mechanical rooms of buildings that dated 50 to 100 years.

For this, Automation Solutions Group (ASG) was called upon to take on the challenge of providing a solution for the city which was reliable, easy to use, and achieved the comfort they were looking for.



ASG utilized American Auto-Matrix® products in ten buildings throughout the city which include City Hall, housing Mayor Francis Slay’s Office, the Mel Carnahan Courthouse, The Juvenile Detention Center, Civil Courts, City Hall West Bonds, St. Louis Streets Department, and three recreation centers.



Concentrating on the ease of use and scope of the project, Automation Solutions Group and American Auto-Matrix worked together to implement AspectFT® throughout the buildings; tying everything together with one easy-to-use front end system.

With thousands of points through the various buildings, the system is using both PUP and BACnet® protocols and is controlling boilers, chillers, large air houses, rooftop units, and more.

The project utilized over 650 AAM controllers, 4 AspectFT-Nexus™, 1 MatrixPNC™, and 1 AspectFT-Enterprise™. ASG is also able to monitor equipment from other manufactures throughout the buildings using the AspectFT system.

There are plans for Automation Solutions Group to add two more buildings to the system, and hopes to control all of the city operated buildings over time.



  • AspectFT-Enterprise, AspectFT-Nexus, MatrixPNC
  • Over 650 BACnet and PUP Controllers
  • More than 1000 points & custom attributes
