March/03/2021 Indoor Air Quality has become an important factor in today’s world as it has a direct impact on the health of building occupants. A building must be well ventilated and the inside air must be free of micro organism for the health and well being of building occupants. As we all have witnessed the pandemic, we have to make sure that the air circulating inside the building must be free of microbes ( Virus , Bacteria & Fungi). UVGI Technology (Ultraviolet Germicidal Irradiation) has been in use for so long for improving air quality as It enhances occupant health, comfort, and productivity. The role of air-conditioning and ventilation, in preventing airborne infections has drawn extensive attention since the SARS outbreak. Ultraviolet Germicidal Irradiation (UVGI) is an air and surface disinfection method integrated with the HVAC system of the building. It uses ultraviolet (UV) light to kill or inactivate Virus by disrupting and destroying its DNA, leaving it unable to perform their vital cellular functions. After using the HVAC system for many years, fungus growth starts inside all corners and joints of the ducts, which subsequently becomes a breeding ground for different kinds of bacteria and viruses. The regular deposit of microorganisms in the ducts and on the coils surface of AHU becomes an invisible health hazard. It should be cleaned for a healthier environment. UVGI is used as a safe alternative to manual or chemical cleaning for a cleaner inside of the HVAC system. As manual cleaning is cumbersome and leads to damage of the coils quite often. Chemical cleaning causes the chemical to remain inside the ducts and AHU coils which slowly come out in the form of minute droplets and vapors when the system is in working condition causing the inhabitants to inhale the same.
