Study of potential for AES

Study: Reduction of fine dust inside a school building

The American Embassy School (AES) is an international school located in New Delhi (India), which offers an educational program for children from pre-kindergarten through Grade 12. A little while ago, ENS performed a study for the AES high school building, to see how much particulate matter our technology can remove in a semi-open courtyard.

Exposure to particulate matter

Fine dust, also called particulate matter (PM), has an important impact on public health. Inhaled particulate matter (particles smaller than 10 micrometer’s) is invisible to the naked eye, but has an immediate negative health effect. Especially the developing brains and bodies of children are affected by the negative health impacts of PM.

Installation air purification systems

The school has a pro-active attitude towards providing its staff and students with a healthy environment. Computational Fluid Dynamics (CFD) simulations were performed to analyze the flow patterns and PM concentration distributions. The published results (see the link below) indicated a reduction potential in a semi-open courtyard to reduce PM exposure for students and staff. Based on the published results the school’s board decided to effectively install four air purification systems in the courtyard. As a result, not only the air will be purified in the courtyard, where both students and staff are spending time during breaks, off-hours and while changing classrooms, but also in the connected classrooms.


To demonstrate the overall performance of our air purification systems, an extensive PM measurements campaign was initialized. Four state-of-the-art Grimm EDM164 environmental dust monitors in combination with four weather stations (Lufft WS500) were used for this. Stay tuned because the results will be shared with you soon. Our advice in the meantime? Make sure you read about the pre-study performed by the University of Technology Eindhoven.
