New Methodology to Evaluate and Optimize Indoor Ventilation Based on Rapid Response Sensors

Area of Science:

• Environmental Science
• Public Health
• Engineering

Background:

• The COVID-19 pandemic highlighted the critical role of ventilation and indoor air quality in public spaces.
• Existing ventilation assessment methods are often intrusive, requiring tracer gases and expert intervention.
• There is a need for continuous, real-time monitoring of ventilation effectiveness.

Purpose of the Study:

• To introduce a novel methodology for continuous ventilation evaluation in public areas.
• To enable space managers to easily assess and adapt ventilation strategies.
• To ensure safe, healthy, and energy-efficient indoor air quality.

Main Methods:

• Utilizing modern rapid response sensors (RRS) for continuous measurements.
• Combining CO2 measurements with space characteristics and activity levels for air exchange estimation.
• Integrating indoor and outdoor RRS pollutant data with health recommendations.
• Developing a web application for direct calculations and continuous evaluation.

Main Results:

• A practical methodology for continuous ventilation assessment was developed and demonstrated.
• The method allows for real-time evaluation of ventilation appropriateness, even during full occupancy.
• The approach offers an improvement over traditional, less frequent assessment methods.
• Potential for integration into adaptive control systems for ventilation management.

Conclusions:

• The proposed methodology provides an innovative and efficient way to monitor and manage indoor air quality.
• It empowers space managers with continuous data for informed decision-making on ventilation.
• This approach can lead to healthier indoor environments and energy savings through optimized ventilation.
