University of Arkansas HVAC UV-C Technology Case Study

This case study details the implementation of ultraviolet germicidal irradiation (UVGI) technology at the University of Arkansas to improve indoor air quality (IAQ) across its campus. Rick Gragg, the HVAC Maintenance Coordinator, has led efforts to retrofit air handling units (AHUs) with UV-C lamps to combat biological growth in HVAC systems. The study outlines the challenges faced due to moisture and biological contaminants that affect air quality and system performance. Gragg's initiative began with addressing complaints about mold in the Health, Physical Education and Recreation Building. The installation of UV-C technology resulted in reduced energy use, increased airflow, and fewer maintenance issues. The case study also presents specific projects, including the successful application of UV-C in various campus buildings, demonstrating significant improvements in air handling efficiency and occupant satisfaction. The university's ongoing commitment to UV-C technology reflects its effectiveness in maintaining clean air and reducing operational costs.
