Airflow Reduction in Cleanrooms after Closing Hours

Cleanrooms and laboratories can save a significant amount of energy by reducing airflow of air handling units (AHUs) after closing hours. Although challenging, airflow reduction is a successful energy reduction measure and has been implemented within the energy reduction program of Janssen Vaccines & Prevention B.V. in Leiden, the Netherlands.
