A Systematic Review on the Application of Ultraviolet Germicidal Irradiation to HVAC Systems

Francesca Cattai,
Annunziata D’Orazio,
Gianluca Sbardella

Abstract: With the renewed focus on indoor air quality (IAQ) due to “Sick building syndrome” and the recent COVID-19 pandemic, the availability of innovative components and innovative guidance for maintenance and systemic safety design will play an important role, with HVAC systems as protagonists. UV-C irradiation has been investigated for a long time, and some system solutions are known. The aim of this work is to provide an overview of the latest outcomes related to the innovative components of HVAC systems using UV-… Show more

“…One of the pivotal uses of AI in Cultural Heritage sites involves monitoring and controlling indoor air quality to prevent the spread of airborne pathogens. AI-driven systems can integrate with HVAC (Heating, Ventilation, and Air Conditioning) technologies to optimize air filtration and circulation, crucial in mitigating airborne transmission risks [ 17 , 18 , 19 , 20 ]. For example, machine learning algorithms can analyze data from air quality sensors to detect patterns indicating deteriorating conditions and automatically adjust HVAC operations to enhance air quality.…”

“…The integration of AI into the management of Cultural Heritage sites has led to innovative applications that address both health safety and operational efficiency. For example, smart HVAC systems [ 17 , 18 , 19 , 20 ] equipped with AI can optimize air filtration and circulation, reducing the risk of airborne diseases. Additionally, AI-enabled surveillance systems can analyze visitor density in real time, triggering alerts when social distancing thresholds are breached, and guiding the deployment of staff to manage crowds effectively.…”

“…Innovative technologies also play a pivotal role in sanitizing indoor environments in historical buildings. One such technology is the use of advanced HVAC systems with HEPA filters and UV-C light sanitization [ 13 , 14 , 15 , 16 ]. HEPA filters are highly effective in trapping particulate matter, including mold spores and dust, while UV-C light has been proven to inactivate a wide range of microorganisms, thus reducing the biological load in the air.…”
