During the coronavirus pandemic, Kinnelon High School in Kinnelon, New Jersey, looked for solutions to ensure ongoing sanitizing in shared learning spaces that would also improve overall indoor air quality. When federal funding became available under the Coronavirus Aid, Relief, and Economic Security (CARES) Act and the American Rescue Plan Act of 2021, the school installed hybrid UV-C air purifier and whole-room disinfection fixtures with embedded occupancy sensors in classrooms, cafeterias, and shared learning spaces.

During the day, air filtration is done when the sensors signal a space is occupied. The air-purifier elements of the fixtures combine HEPA, high-intensity UV-C, and active carbon filtration to perform the ASHRAE-recommended two or more air changes per hour to improve air quality and reduce pathogens. At night, automated, chemical-free disinfection of the air and surfaces occurs in unoccupied spaces throughout the school.

Avenues World School – New York Campus in New York City is recognized in the Germicidal Ultraviolet (GUV) Systems for Energy Savings and Improved Indoor Air Quality (IAQ) category. The school installed GUV luminaires across its campus to reduce the spread of COVID-19 and other airborne infectious diseases. Upper-room luminaires were installed in the cafeteria, corridors, gym areas, choral classrooms, and theater. Whole-room far UVC luminaires were installed in all classrooms. One assessed classroom was found to deliver between 0.9 and 4.6 equivalent air changes per hour (eACH) while only using 15 watts. The upper-room GUV installation in the cafeteria was found to deliver at least 12.5 eACH while using 386 watts.
