The ongoing development of systems for continual, multi-point monitoring of key IAQ parameters is expanding the ways that can be used to optimize building performance by reducing uncertainties associated with the ventilation component of the HVAC system. The monitoring data provide specific details, not only on ventilation, but also on related areas that permit improved operation for both IAQ and energy consumption. The specific information provided on ventilation performance includes
- determination and evaluation of the adequacy of the ventilation rates achieved,
- determination of the percentage of outdoor air in the supply air as a function of the mechanical system components involved, including the outdoor air damper position,
- effectiveness of the overnight purge of the building in its elimination of air contaminants of human origin,
- identification of indoor sources of moisture,
- identification of potential energy savings in areas that are significantly overventilated,
- identification of the magnitude and frequency of reentrainment of building exhaust and the presence of vehicle exhaust at the outdoor air intakes,
- discovery of other ventilation problems, and
- rapid evaluation of the effectiveness of corrective measures to correct these problems.
