If you’re a dental or other healthcare professional, customers no doubt appreciate your use of personal protective equipment (PPE), routine equipment sterilization and easy-to-clean fabrics and furniture. There’s a definite reassurance when a healthcare professional opens a fresh set of latex gloves or instruments.
To truly protect your clients from infection, however, practitioners need to move beyond instrument sterilization and address the invisible risks in the surrounding air.
Many factors can impact a building’s environmental performance and the consumption of energy, water and materials. Manufacturers of building systems design performance around a specific, optimal condition. Over time, these performance standards will deteriorate if nothing is done to preserve the original “as-built” condition.
ASHRAE recently released two position documents (links listed below) examining the health consequences of using filtration and air cleaning technologies in HVAC systems. Our own Dean Saputa is an active member of one of the committees responsible for this research (the ASHRAE Filtration and Air Cleaning Position Document Committee).
Modern UV-C lamps are similar to the fluorescent lamps typically found in ceiling fixtures. Both types of lamps are manufactured on fluorescent lamp machines in, essentially, the same lengths and diameters. Both lamps operate using an identical electrochemical processes: an electric discharge through argon gas strikes mercury vapor to generate a photon with a wavelength of 253.7 nm (typically called UV-C), which is invisible.
We are in the midst of an HVAC revolution as the number of mechanical engineers specifying UV-C in all building types is mushrooming at historic levels.
