According to the National Federation of State High School Associations’ and the Sports Medicine Advisory Committee’s “Guidance for opening up high school athletics and activities,” decreasing potential exposure to respiratory droplets is critical to preventing the spread of COVID-19 in athletic facilities. It recommends “adequate cleaning schedules should be created and implemented for all athletic facilities to mitigate any communicable diseases; and prior to an individual or groups of individuals entering a facility, hard surfaces within that facility should be wiped down and sanitized (chairs, furniture in meeting rooms, locker rooms, weight room equipment, bathrooms, athletic training room tables, etc.).”
In 2019, voters in Chelsea, Mich., approved an $81 million school bond issue, paving the way for several projects, including a new auxiliary gymnasium to relieve an overcrowded facility at the high school. The school district planned to improve its weight training offerings for students and expand access for middle-school athletes and the community. The new facility would include two basketball practice courts, a competition court, and a 6,500-square-foot weight room.
Engineer Rich Coburn, a project manager at Strategic Energy Solutions, in Berkley, Mich., along with project architect Kingscott, in Kalamazoo, Mich., knew the weight room would be a popular destination and prioritized occupant health and safety in its design. Exercise facilities are considered high risk for transmission because of their enclosed environment, shared equipment, and close contact between users and staff. “There are always concerns about germs and bacteria when you create spaces such as weight rooms,” Coburn says. “When this project came up, it seemed like the perfect space to utilize 405-nm lighting technology.”
Using a combination of 405-nm indigo and white LEDs, Coburn specified Kenall Manufacturing’s Millenium Stretch luminaires, which use Kenall’s dual-mode Indigo-Clean technology to emit narrow spectrum light that kills viruses and bacteria while providing ambient illumination for the space. The luminaires use this wavelength, which falls into the visible light spectrum, to continuously deactivate harmful microbes in the air and on surfaces. When the space is occupied, the luminaires operate in white disinfection mode. When the facility is closed, the fixtures switch to indigo light to provide a higher level of disinfection.
Standard room occupancy sensors control the operating mode, and the electrical inputs are identical to a typical LED luminaire. The continuous whole-room disinfection technology kills many harmful pathogens, including SARS-CoV-2, influenza A, and methicillin-resistant Staphylococcus aureus (MRSA).
