Ventilation is one of the most basic engineering controls in any building. A commercial ventilation system removes indoor pollutants, helps manage moisture, supports comfort, and can help lower the risk of airborne disease in occupied spaces. In industrial and large-scale commercial facilities, where processes, equipment, and more people can create more contaminants, ventilation is not optional. It is a core part of a safe, functional building. Commercial ventilation systems are also tied to commercial indoor air quality (IAQ). Facilities that under-ventilate often see pollutant levels rise, humidity problems spread, and more worker complaints. Good IAQ is about more than comfort. It affects health, safety, and compliance. Knowing how ventilation works, which standards apply, and how to judge performance is the first step to a healthier building.

Despite being the least visible of building systems, ventilation is often the most important. Ventilation impacts people, productivity, comfort, energy, building performance, and, most importantly, indoor air quality. It’s essential to know the indoor air quality (IAQ) in your facility for many reasons.Healthwise, air pollutants can cause irritation, dizziness, fatigue, and asthma symptoms in the short-term, and can lead to respiratory diseases, heart disease, and cancer in the long-term. Additionally, poor ventilation can cause temperature and pressure imbalances which lead to comfort and productivity issues. Finally, the lost conditioned air due to poor ventilation forces your HVAC systems to work harder, which raises your HVAC costs. In this blog, we’ll outline what to lookout for to ensure your IAQ is where it needs to be, provide reference points to give you benchmarks for your IAQ, and point out potential solutions that fit your facility needs.
