Covid-19 Considerations – Germicidal UV lights - Shared screen with speaker view
AEE Utah Chapter
Thank you all for being here today!
Thanks AJ and Jody!
What's the IES?
Illuminating Engineering Society
IES sets many of the guidelines and criteria used for designing lighting for best use.
When you say bacteria, does that encompass viruses as well?
Do the direct systems have trouble disinfecting areas that are shadowed?
Is there any info about cost of implementation?
What application would you recommend installing these systems?
Is there a rule of thumb (equation) that relates time/distance/distribution/effectiveness?
Would you say that G-UV is more or less effective against viral disinfection that it is against bacterial disinfection?
Due to the short time that virus particles are passing through a duct (< 1 sec exposure to lights), what wattage range are you thinking would be effective (W/CFM or W/ duct cross sectional area)
What amount of disinfection efficacy, if any, do commercially GUVs inside HVAC systems offer?
I had a vendor claim to use a specific wavelength of blue light as an alternative to UV. Can you comment on this?
Could we get a copy of this presentation emailed to us?
To clarify, a correctly designed, installed and operated GUV system inside HVAC ducts can disable up to 99.9% of pathogens exiting the duct, even though the exposure time is miniscule?
AEE Utah Chapter
To further clarify, In the context of COVID-19, good GUVs in HVAC systems can reduce the amount of pathogens in buildings
What is the legal implication for installing a GUV system that could potential harm occupants or maintenance workers?
Any case studies that have shown the effectiveness of GUV?
World class presentation and discussion! Thanks all!
