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.
