Conditioning outdoor air is one of the most energy-intensive processes in a building. Without proper measurement and control, HVAC systems often over-ventilate, leading to wasted energy and higher costs.
According to the U.S. Department of Energy, commercial buildings consume 44% of their on-site energy for heating, cooling, and ventilation. Additionally, light commercial HVAC systems condition over 50% of all commercial floor space, making their efficiency critical for cost savings.
Many light commercial systems lack the equipment to precisely measure and regulate outdoor air intake, making it difficult to:
✅ Maintain indoor air quality (IAQ)
✅ Verify compliance with ventilation codes
✅ Prevent unnecessary energy waste
Wind Pressure & Over-Ventilation
Most light commercial units do not compensate for wind pressure, hysteresis, damper binding, or actuator slippage. Wind can force excess outdoor air into a building, straining HVAC systems and increasing energy costs.
Damper Binding & Actuator Slippage
Hysteresis—when dampers fail to return to their original position—can cause uncontrolled outdoor air intake, forcing HVAC systems to work harder and consume more energy. Without monitoring, damper failures often go unnoticed, leading to persistent over-ventilation and unnecessary expenses.
GreenTrol’s precision thermal dispersion airflow sensors and integrated controls optimize HVAC performance by:
✅ Ensuring precise outdoor air measurement to prevent over-ventilation
✅ Maintaining proper airflow in outdoor, supply, return, and exhaust systems
✅ Reducing energy waste while supporting healthy IAQ and pressurization
✅ Compliance with building codes
