Ventilation system O and M: A first step for improving IAQ
- City of Columbus, OH (United States)
The author identifies six common operations and maintenance (O and M) problems in ventilation systems and discusses their solutions. The study was conducted in a Columbus, Ohio, high-rise office building that was operated with minimum (Vmin) and maximum (Vmax) outside air ventilation. Both the perceived indoor air quality (IAQ) and the IAQ in terms of physical and chemical parameters were measured and reported previously. The new study revealed a significant practical observation: that IAQ complaints can often be resolved with proper ventilation system operation and maintenance (O and M). Extensive IAQ measurements revealed outside air was about 150 L/s (71 cfm) per person (as estimated from afternoon carbon dioxide measurements), and both the indoor and ambient air pollutant levels were very low. The IAQ complaints were resolved through a comprehensive operations and maintenance (O and M) assessment, and subsequence ventilation system O and M improvements.
