IES sets many of the guidelines and criteria used for designing lighting for best use.
Conrad Duerr

When you say bacteria, does that encompass viruses as well?
Alyssa Kay
01:20:04
Do the direct systems have trouble disinfecting areas that are shadowed?
Sarah Boll
01:30:15
Is there any info about cost of implementation?
Cameron Scott
01:30:27
What application would you recommend installing these systems?
Justin Owen
01:30:58
Is there a rule of thumb (equation) that relates time/distance/distribution/effectiveness?
Conrad Duerr
01:31:18
Would you say that G-UV is more or less effective against viral disinfection that it is against bacterial disinfection?
Glen Anderson
01:31:59
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)
Lin Alder
01:31:59
What amount of disinfection efficacy, if any, do commercially GUVs inside HVAC systems offer?
Justin Owen
01:32:01
I had a vendor claim to use a specific wavelength of blue light as an alternative to UV. Can you comment on this?
Jason Gordon
01:34:53
Could we get a copy of this presentation emailed to us?
Lin Alder

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?

To further clarify, In the context of COVID-19, good GUVs in HVAC systems can reduce the amount of pathogens in buildings
Cameron Scott
01:49:05
What is the legal implication for installing a GUV system that could potential harm occupants or maintenance workers?
Cameron Scott
01:53:57
Any case studies that have shown the effectiveness of GUV?
Lin Alder

World class presentation and discussion! Thanks all!
