What is Ultraviolet Germicidal Irradiation (UVGI) (UV-C)? Upper-room Ultraviolet Germicidal Irradiation (UVGI) involves the use of UVC to inactivate airborne pathogens. Wall or ceiling-mounted UVC fixtures are placed near the ceiling to generate a UVC field at 254 nm...

HVAC for Built Environment The main purpose of heating, ventilation, and air conditioning (HVAC) for buildings is to maintain a healthy and comfortable indoor environment for occupants. Air is the primary carrier of heat, moisture, and airborne contaminants in indoor...

What is Ultraviolet Germicidal Irradiation (UVGI) (UV-C)? UVGI involves electromagnetic radiation in the UVC band of 200-280 nm which destroys the reproduction ability of microorganisms including viruses, bacteria, and fungi. Traditionally the upper-room UVGI-UVC has...

Building Ventilation and Airborne Transmission of Infectious Aerosols Air is the primary carrier of heat, moisture, and airborne contaminants including infectious aerosols in indoor spaces. The primary goal of building ventilation is to create a healthy environment...
