Outdoor air delivery monitoring

EQc1 | Possible 1 point


Provide capacity for ventilation system monitoring to help sustain occupant comfort and well-being.


Install permanent monitoring and alarm systems that provide feedback on ventilation system performance to ensure that ventilation systems maintain design minimum ventilation requirements in a form that affords operational adjustments:

  • For mechanical ventilation systems that predominantly serve densely occupied spaces (those with a design occupant density greater than or equal to 25 people per 1000 sq. ft), install a CO2 sensor within each densely occupied space.
  • For all other mechanical ventilation systems, provide an outdoor airflow measurement device capable of measuring the minimum outdoor airflow rate at all expected system operating conditions within 15% of the design minimum outdoor air rate.
  • For natural ventilation systems, install a CO2 sensor within each naturally ventilated space.
