While the answer may seem simple, the reality is more complex. Ventilation plays a critical role in maintaining healthy indoor environments by diluting contaminants and supporting occupant well-being—but its effectiveness depends on more than just airflow volume. This article explores:
- Why mass flow (not just cfm) matters for effective ventilation
- The limitations of relying on CO₂ as a standalone indicator
- How energy-driven decisions have historically led to under-ventilation and IAQ issues
- Why today’s buildings require a better balance between energy and indoor air quality
