Imagine stepping into a conference room after lunch. The air feels heavy, a faint mustiness lingers, and within minutes, your focus starts to fade. Now picture the same room with fresh, clean air circulating. The conversations flow, energy rises, and the space feels alive. That difference is the power of indoor air quality (IAQ).
What Is Acceptable IAQ?
Acceptable indoor air quality goes beyond simply “fresh air.” It means air that is free from harmful levels of pollutants, odors, and moisture, while maintaining comfort for occupants. Standards like ASHRAE 62.1 define minimum ventilation rates to achieve this balance, ensuring that buildings protect both people and performance.
Why IAQ Is Critical
Indoor environments can trap contaminants more easily than outdoor spaces. Without proper ventilation, pollutants accumulate, leading to health risks and reduced productivity. Acceptable IAQ is about creating spaces where people can breathe safely, think clearly, and feel comfortable.
Common Airborne Contaminants
- Biological agents: Mold spores, bacteria, and viruses
- Chemical pollutants: Volatile organic compounds (VOCs) from paints, cleaning products, or furnishings
- Particulates: Dust, smoke, and fine particles that irritate lungs
- Moisture & humidity: Excess dampness that fosters mold growth
Each of these can compromise health, cause discomfort, or damage building systems if not properly managed.
The Path Forward
Standards like ASHRAE 62.1–2025 refine how we measure and control ventilation, humidity, and contaminant removal. They provide building professionals with clear guidance to design and operate systems that keep air clean, safe, and comfortable.
Indoor air quality isn’t just a technical requirement—it’s a human necessity. By prioritizing IAQ, we create healthier workplaces, schools, and homes where people can thrive. Explore ASHRAE 62.1–2025 on BSB Edge and lead the way in ventilation excellence.
