Measuring indoor air quality improvements after sustainable renovations (metrics)

Key metrics include measuring levels of particulate matter (PM2.5, PM10), volatile organic compounds (VOCs), carbon dioxide (CO2), humidity, and temperature. A reduction in these pollutants indicates improved air quality.

VOC levels can be measured using air quality monitors specifically designed to detect VOCs. Professional air quality testing services can also provide accurate readings and identify specific VOC sources.

Ventilation is crucial for diluting indoor pollutants and introducing fresh air. Proper ventilation systems, such as mechanical ventilation with heat recovery (MVHR), can significantly improve air quality by removing stale, polluted air and bringing in filtered, fresh air.

Initially, monitor air quality frequently (e.g., daily or weekly) for the first few months after renovation. Once the air quality stabilizes, you can reduce monitoring to monthly or quarterly intervals.

While there isnt a specific renovation-related certification, look for products and materials with certifications like Singapore Green Label, GreenGuard, or similar eco-labels that indicate low VOC emissions.

Cost-effective strategies include using low-VOC paints and materials, ensuring proper ventilation during and after construction, regularly cleaning air filters, and introducing indoor plants that help purify the air.
