Enhancing Efficiency & Indoor Air Quality (IAQ)

Light commercial HVAC systems account for more than 50% of today’s heating and ventilating needs. Although energy efficiency ratios have dramatically improved over the past several decades, outdoor air ventilation control has been ignored. Proper OA ventilation is essential for maintaining IAQ, thermal comfort, and building code compliance. Without accurate control, systems risk:

Wasting energy through over-ventilation
Compromising IAQ and comfort
Producing poor temperature and humidity control

The Problem with Traditional Ventilation Methods

Conventional OA control approaches often fail, leading to ventilation errors exceeding 50%. Common issues include:

Fixed damper positions or fan speeds that don’t adjust to real-time building conditions
CO₂-based control that inaccurately estimates OA needs
Temperature-ratio methods that provide unreliable airflow measurements

the greentrol advantage

By integrating GreenTrol solutions into your HVAC system, you can:

Compensate for system effects like wind and pressure variations
Detect damper binding, fan failures, or actuator slippage in real time
Ensure compliance with ventilation codes through precise OA measurement
Improve IAQ and occupant comfort with accurate OA delivery
