When it comes to managing air quality, energy efficiency, and occupant comfort in buildings, airflow management is no small feat. For facility managers, technicians, and building owners, the ability to measure and monitor airflow accurately can be the difference between a well-optimized building and one plagued with inefficiencies. Enter the KMC Airflow Management System (AFMS)—a cutting-edge solution that simplifies complex airflow problems using smart, cost-effective technology.

With this blog, we’ll explore the typical components of an AFMS, compare setups, and show how KMC AFMS can help you optimize airflow, save energy, and improve indoor air quality in one seamless solution.

What is an Airflow Management System (AFMS)?

An AFMS enables buildings to measure, monitor, and adjust airflow in HVAC systems to meet performance standards for energy use and indoor air quality. These systems are critical for maintaining compliant air changes per hour (ACH), reducing energy waste, and ensuring occupants breathe safe, clean air.

The AFMS is foundational in achieving certifications like WELL and LEED, where maintaining proper ventilation and air quality standards is key. Beyond compliance, the ability to measure airflow reduces the risk of “sick building syndrome,” improves HVAC lifespan, and ultimately contributes to a healthier, more productive indoor environment.

Why Are There Different Setup Configurations?

Not every building or HVAC system is the same, so AFMS setups often vary based on a facility’s size, design, and the unique HVAC challenges it faces. For example:

• Education buildings, like Denver Public Schools, depend on precise airflow measurements to ensure consistent IAQ for classrooms.

• Healthcare facilities, such as Children’s Minnesota, require systems that meet stringent ASHRAE standards for pressurization and cleanliness.

• Commercial offices and retail spaces may prioritize energy efficiency while maintaining comfortable temperatures and ventilation for occupants.

Each setup also depends on environmental factors like duct layout, damper design, and operating pressure units. For instance, sharp bends or duct restrictions may require specialized airflow measuring devices or recalibration to ensure accuracy.

Components of a Typical AFMS

An AFMS comprises several key components working together to measure and regulate airflow. These typically include:

• Airflow Probes: Positioned on supply and return fans, these help identify air pressure changes to optimize air delivery.
• Temperature Sensors: Measure conditions such as outside air (OA), return air (RA), and mixed air (MA) to ensure proper mixing and delivery to HVAC zones.
• Airflow Sensors: Devices such as inclinometers provide independent measurement of the OA/MA damper system, used as a reference for the CAP table.
• Communication Protocols (BACnet/IP): Ensure seamless integration with building automation systems for real-time monitoring and diagnostics.
• Airflow Monitoring Stations: Provide visual interfaces to observe airflow data and diagnose issues like damper deterioration or airflow drift.

The goal? To create a reliable and accurate airflow measurement system that maximizes HVAC performance while minimizing costs.

Decision Criteria for Choosing an AFMS

When choosing an AFMS, consider these factors:

• Accuracy and Repeatability: Can the AFMS handle challenging setups, like systems with irregular duct configurations or low air velocities? KMC AFMS solves these issues with inclinometer-based measurements, bypassing common limitations of traditional differential pressure or thermal dispersion methods.

• Cost-Effectiveness: Does the system minimize costs by reducing the need for multiple airflow devices? KMC AFMS uses a single controller to manage what traditional setups often require several tools to accomplish.

• Ease of Maintenance: Does the system recalibrate automatically to reduce downtime? KMC’s patented Characterized Airflow Performance® technology ensures continuous accuracy, even as mechanical components age or conditions change.

• Energy Efficiency Goals: Does the system align with your energy-efficiency targets? KMC AFMS helps to maintain sustainable HVAC solutions by monitoring airflow and ensuring air changes per hour are optimized without wasting energy.

• Compliance Requirements: Does the system meet ASHRAE standards for ventilation and airflow measurement? Proper ventilation rates ensure compliance with certifications like WELL and RESET.

How KMC AFMS Leads the Pack

KMC Controls offers a modern alternative to traditional airflow measurement instruments, which are prone to inaccuracies due to duct bends, debris, or environmental variables. Here’s what sets the KMC AFMS apart:

• Automatic Recalibration: The AFMS uses automated Learn Mode functionality to recalibrate airflow curves regularly, eliminating manual recalibration and saving valuable technician time.

• Real-Time Monitoring & Diagnostics: Integrated sensors and NetSensor displays allow facility managers to monitor ACH, airflow rates, and advanced diagnostics, helping identify issues like damper blade wear before they become costly maintenance problems.

• Cost Savings: By requiring fewer measurement devices and minimizing installation modifications, KMC AFMS reduces upfront and maintenance costs significantly compared to traditional setups.

• Versatility Across Industries: Whether it’s improving indoor air quality in classrooms, maintaining pressurization levels in hospitals, or optimizing ventilation in an office, KMC AFMS fits any building type and adjusts to unique requirements seamlessly.

Case Studies That Prove (and Optimize) Performance

Take it from two standout case studies on KMC AFMS applications:

Denver Public Schools

The challenge? Meeting ASHRAE standards while addressing IAQ concerns across 207 schools for over 90,000 students. The result? The KMC AFMS delivered impressive accuracy using fewer devices and offered proactive fault detection, saving resources and reducing equipment downtime.

Children’s Minnesota

With pressurization and ventilation challenges jeopardizing patient safety, Children’s Minnesota turned to KMC AFMS. The result? Reliable airflow and pressurization data compliant with health standards, plus virtually zero maintenance requirements, earning trust within their healthcare system.
