Why Logansport State Hospital Breathes Easier Now

When you work in a psychiatric or behavioral health facility, you already have enough on your plate. The last thing anyone wants to worry about is whether the building’s air handling systems are behaving the way they should. Comfort, safety, and stability aren’t “nice-to-haves”—they directly influence how patients feel, how staff work, and how the entire environment functions day to day. 

That’s exactly why the team at Logansport State Hospital began looking for a better way to manage airflow. Their thermal dispersion sensors were inconsistent, causing real frustrations on the ground. But like many facilities, they didn’t have the luxury of major shutdowns or a full mechanical overhaul.  

So, they explored a different option: TrueFit AFMS® powered by KMC Controls’ building automation expertise. As one of our technical writers* explained, it’s like having an automated Testing and Balancing technician in a box, ready to do their work at any time and without having to pay them an ongoing salary! 

The Everyday Challenges They Faced 

Psychiatric hospitals deal with unique building pressures (literally and figuratively). Rooms need the right ventilation, the right temperature, and the right level of air circulation to help everyone feel calm and comfortable. 

At Logansport, that balance had become difficult to maintain. Their team was running into issues like: 

• Outdoor air levels drifting too high or too low 

• Dampers not responding the way they should 

• Mixed-air temperatures jumping around unexpectedly 

• Staff needing to troubleshoot the same problems repeatedly 

• A general sense that the system just wasn’t trustworthy 

These might sound like technical problems—and they are—but they also affect people. Unstable temperatures or poor ventilation can add unnecessary stress in spaces where peace and predictability matter deeply. 

It’s understandable; it can be frustrating to have to do guesswork and manual adjustments to AHUs to try and maintain proper airflow balance and pressurization of spaces. There can also be pressure to balance outside air requirements with energy use, since the more outside air you bring in, the higher the cost of giving that air a comfortable temperature and humidity level. At the same time, you still need an appropriate amount of outside air for the health of the occupants.  

This is where TrueFit AFMS comes in, giving an accurate system-level view that allows you to hit the right balance. Not over or under ventilating. 

A Smarter Way Forward  

TrueFit AFMS replaced their older, less reliable thermal dispersion sensors and added more system-level visibility into the balance of airflows in the AHU. 

Prior to this, their system utilized a tube to try to get smooth, stable airflow, but this did not improve the accuracy of the readings, as many ways of measuring OA flow do not do well with turbulent air. However, TrueFit AFMS includes our Characterized Airflow Performance method which has no trouble with that. 

With real-time airflow monitoring, automated damper adjustments, smarter mixed-air temperature control, and ongoing performance tuning, TrueFit AFMS acted like a brain upgrade for their existing AHUs.

What Happened Next? A Noticeable Difference—Quickly. 

Once TrueFit AFMS was installed, the improvements were easy to see: 

🌬️ Ventilation stabilized:  Outdoor air levels were more consistent, helping create healthier, safer spaces. 

🛠️ Less mechanical strain:  Equipment ran more predictably and efficiently, which meant fewer surprises for staff. 

💡 Energy use dropped:  Their AHUs saw roughly an 18% reduction in energy consumption—a meaningful cost savings. 

😊 Comfort improved:  Hot spots and cold spots smoothed out, creating a calmer, more controlled environment for patients and staff. 

All of this was achieved without costly modifications to the AHUs. 

Why This Matters for Other Facilities 

Logansport’s situation is far from unique. Many psychiatric and behavioral health facilities face: 

• Aging HVAC equipment 

• Challenging pressurization requirements 

• Strict regulatory expectations 

• Limited capacity for disruptive upgrades 

TrueFit AFMS was created specifically to help facilities overcome these challenges in a practical, cost-effective way. It’s not about reinventing your building. It’s about making what you already have smarter, more stable, and easier to trust.
