Ashrae Update
ASHRAE and IUVA Sign Memorandum
of Understanding
ATLANTA — ASHRAE and the International Ultraviolet Association
(IUVA) have signed a new Memorandum of Understanding
(MOU) formalizing the organizations’ relationship.
The MOU was signed by Charles E. Gulledge III, P.E., 2020-21
ASHRAE President and Ron Hofmann, President of IUVA, University
of Toronto, via electronic signature in April to further
specify the path forward. The agreement defines parameters
by which ASHRAE and IUVA will work cooperatively to promote
the advancement of emerging research and technologies
to support a more sustainable built environment.
“Establishing and maintaining improved indoor environmental
quality is the bedrock of ASHRAE’s sustainability mission
and the use of ultraviolet technology is a critical component
towards addressing the challenges of minimizing the spread
of infectious diseases,” said 2020-21 ASHRAE President
Charles E. Gulledge III, P.E. “We are pleased to partner with
IUVA as we collectively support research and new innovations
to further our vision on a sustainable built environment
for all.”
• Standards and guidelines that establish the minimum
requirements for commissioning permanently installed UV
antimicrobial systems in existing and newly constructed
facilities.
• Standard and guidelines for the application of UV disinfection
of water used in cooling towers to control spread
of bacteria, such as Legionella, algae and fungi into the
building HVAC system.
In addition to these research and publication development
initiatives, ASHRAE and IUVA’s other areas of potential collaboration
include general advocacy, joint conferences and
meetings, consistent leadership communication, education
and professional development, technical activities coordination,
and research.
“With a focus on the science and engineering of UV technology,
IUVA members are pleased to have the opportunity
to partner with ASHRAE to enhance the knowledge base
and application of UV in the built environment,” said IUVA
President Ron Hofmann. “While the technology is already
well established, the urgency of addressing the global
pandemic has raised the profile the UV, and our partnership
with ASHRAE promises to help develop the necessary data,
protocols, guidelines, and standards to ensure its continued
effective, safe use.”
The MOU includes, but is not limited to, the following initiatives
related to development of ANSI certifiable standards
and related source documents:
• Test and measurements on specific pathogens across a
specified light spectrum (e.g., antimicrobial UV-C: 200nm
- 280nm) and in specified mediums (e.g., aerosols, large
droplets, surface – dry & wet, in aqueous solution, pristine
& soiled).
• Test and measurements on efficacy outcomes for antimicrobial
UV-C devices and systems in specified, well defined
testing environments (e.g., simulated hospital rooms,
equipped and arranged in a standardized configuration,
with predetermined numbers and locations of sampling
points).
• Test and measurements on efficacy outcomes for antimicrobial
UV-C devices and systems installed in ‘upper room’
HVAC applications.
