ASHRAE, IUVA sign MoU
ATLANTA, Georgia, 12 May 2021: ASHRAE and the International Ultraviolet Association (IUVA) have signed a new Memorandum of Understanding (MoU), formalizing the relationship between the two organizations, ASHRAE said through a Press release.
Charles E Gulledge III, 2020-21 ASHRAE President, and Ron Hofmann, President, IUVA, signed the MoU in April to further specify the path forward, ASHRAE said. 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, ASHRAE further said.
“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,” Gulledge said. “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.”
Hofmann added: “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. While the technology is already well established, the urgency of addressing the global pandemic has raised the profile of UV, and our partnership with ASHRAE promises to help develop the necessary data, protocols, guidelines, and standards to ensure its continued effective, safe use.”
According to ASHRAE, 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
- 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
ASHRAE said that in addition to these research and publication development initiatives, ASHRAE’s 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.
ASHRAE publishes updated health care facility ventilation standard
ATLANTA, Georgia, 11 May 2021: ASHRAE has released an updated edition of ANSI/ASHRAE/ASHE Standard 170, Ventilation of Health Care Facilities. Making the announcement through a Press release, ASHRAE said the standard offers guidance, regulation and mandates to designers of health care facilities.
The 2021 edition, ASHRAE said, delivers critical guidance for designers and operators of these front-line facilities and incorporates 17 addenda to the 2017 edition of the standard.
According to ASHRAE, changes include:
- Expanded requirements to allow airborne infectious isolation room exhaust discharge to general exhaust under certain conditions
- Revised scope, with improved guidance on thermal comfort conditions
- Extensive modifications to address the Outpatient and Residential sections
- Extensive revisions to air filtration requirements
- Addition of new columns in the ventilation tables to prescribe filtration requirement and designate unoccupied turndown
- Expanded guidance on separation distance requirements for varied intake and exhaust arrangements, coordinating with related ASHRAE Standard 62.1 data
- Improved guidance related to behavioral and mental health
