How are airflow rates calculated for different room types and loads in a Flexit-designed ventilation system?

Correct calculation of airflow rates is essential for a healthy indoor climate, good comfort and energy-efficient operation. Many want to understand which requirements and recommendations form the basis for airflow rates in different rooms, and how occupancy and usage are taken into account.

Airflow rates are calculated based on the minimum requirements set out in TEK17 for the different room types. In addition, Flexit applies its own professional recommendations to ensure a healthy indoor climate, proper air quality and good comfort during normal use of the dwelling. Occupant load, room function and expected usage are included in the assessment, ensuring that airflow rates are adapted to both regulatory requirements and practical needs.
