Cleanroom

A specially constructed space environmentally controlled with respect to airborne particles (size and count), temperature, humidity, air pressure, airflow patterns, air motion, and lighting.

Technical

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.
