Despite the pandemic, standards development has been robust with increased committee participation despite the challenges !  This presentation will provide an overview and update on developing IAQ related standards in ASTM and ISO , such as PRV, micro vacuuming, legionella, sampling strategy and more.  Highlights of the standard drafts as well as the obstacles and issues being debated will be presented. Takeaway: Understanding how true consensus standards are developed and that everyone can and should participate. Recognizing that consensus is…

Keep up to date on airborne disease transmission news from across the world! Gain a global cutting-edge perspective from the US former National Science and Technology Executive Director, and leading Microbiologist and Molecular Biologist, Dr Jayne Morrow on curtailing airborne disease transmission.  Dr Morrow will describe the journey she has taken through Government Policy and a background spanning from Civil Engineering to Molecular Biology and describe what led her to creating the Integrated Biosecurity and Built Environment Consortium – IBEC…

Abstract Biological materials in airborne particles (PM) have diverse sources, formation processes, composition and sizes. Knowledge has advanced substantially in recent years with regards to PM physical properties (mass, number, size) and chemical composition (chemical speciation).  However, less progress has been made in the characterisation of biological materials in PM and the interaction between its abiotic and biological components. This significantly limits understanding of the role and impact of PM in the context of public health (allergenicity, toxicity, infectivity), climate…

Many mistakenly assume that by following applicable building code and guidelines such as ASHRAE, they are providing properly decontaminated air. And, although the HEPA filter remains the best filter available for ventilation systems, like all filters there exists a determinable inefficiency zone that belies the myth that HEPA is the ultimate answer for air decontamination. To complete the air decontamination process initiated by filtration, Ultraviolet Germicidal Irradiation (UVGI) needs to be added. UVGI has a long history of being used for…
