By using sensors that are already in place or installing cost-efficient IoT sensors, certification does not rely on one-time manual measurements. The sensor telemetry gives a year round picture of the indoor air quality or utilization that is more reliable than single sample measurements. With a continuous data stream, the performance and improvement efforts can be managed over time.
Complementing the sensor array to support a certification use case gives an approximate 30% cost advantage compared to manual measurements. However, with typical re-certification cycles of 3-5 years, the same sensors can serve many subsequent cycles where a +85% cost advantage can be achieved. Moreover, the sensor telemetry can be used to power many other applications and use cases, making the ROI on sensor driven certification even better.
