Optical Measurement of Ventilation Effectiveness
THE CHALLENGE
Our project enables simple and cost-effective measurement of ventilation effectiveness in buildings and industrial spaces. Clean, well-distributed indoor air is crucial for health and productivity in schools, offices, factories and cleanrooms. Current methods to measure ventilation effectiveness are complex and expensive, making regular checks difficult. This leaves operators unsure if systems provide adequate air quality. Our solution enables fast, reliable, and affordable assessment, helping optimize ventilation, save energy, and ensure safe, healthy indoor environments.
Flexible and accurate measurement: Optical line-of-sight measurement allows mapping
air changes across variable room areas, validated with good accuracy.
Environmentally friendly tracer: Harmless suspended aerosols replace climate-harmful
tracer gases for realistic airflow tracking.
Cost-effective and simple: The system uses off-the-shelf components, making it affordable
and easy to manufacture for widespread use.
