Prezant offers 20+ years of experience assessing air quality and ventilation in public buildings, including schools, offices, laboratories, industrial and manufacturing facilities, and single and multi-family residential.
With certification, credibility, and authority in public health and HVAC engineering, Prezant offers a unique combination of skills and consultation based on evidence-based science and public health.
Our services include desktop assessments, site visitations, remote assessments, infection risk modelling, chemical assessments, and ventilation assessments. These range from simple to highly complex, including tracer gas studies using smoke, carbon dioxide, and/or sulfur hexafluoride (SF6) to quantitatively measure air exchange.
Prezant assists insurance companies, real estate entities, individuals, strata associations, building owners & managers, and manufacturers assess and manage their working and built environments.
For new construction, we employ WELL-accredited professionals and WELL-certified performance testing agents to optimise indoor air quality and comfort.
For gases, vapours, or particles in air, instrumentation and/or laboratory analysis can determine if a hazard is present, and if so, at what concentration in air.
Through direct measurement of airflow or using tracer gases, Prezant Environmental can provide a performance test in residential or commercial spaces, and determine effective air changes.

Certified Occupational Hygienist
Brad Prezant is a public health and occupational health scientist, with epidemiology and public health perspective. He works primarily as a consultant, with additional experience as a University-based research scientist. He has assessed indoor air quality and ventilation in airports, hospitals, public buildings, and schools since 1979, including the residence of Amazon's chief executive, Jeff Bezos. He is one of 50 persons worldwide with the designation, Certified Industrial Hygienist (CIH), sub-specialty Indoor Air Quality.
In 2020 & 2021, Mr. Prezant assessed ventilation and airborne transmission of COVID-19 in various public buildings and schools, designed the first easy-to-use risk calculator for calculating the risk of COVID-19 infection, and supervised a team of engineers & contractors to re-design hotel quarantine ventilation on behalf of Coronavirus Quarantine Victoria.
Mr. Prezant is the author of numerous professional documents published by professional societies, including the first edition of Recognition, Evaluation, & Control of Indoor Mold, published by the AIHA, documents from AIRAH, and was a contributor to the Harvard School of Public Health document on airborne transmission of COVID-19 in airports. He is a frequent speaker on topics related to indoor air quality, bushfire smoke, asbestos, methamphetamine labs, and ventilation.
Mr. Prezant is an independent expert for select cases regarding SARS-CoV-2, mould, asbestos, air pollution and cardiovascular disease, and indoor air quality in Australia, New Zealand, and the U.S.
Mr. Prezant assesses built environments for a range of airborne hazards including chemicals, pollutants, and ventilation effectiveness.
Schools are re-opening throughout Australia. School administrators and teachers are concerned about the safety of children and staff. There are many more questions about the best way to protect children from COVID-19 infection at school than there are answers.
School administrators are being bombarded by vendors selling a myriad of products, some of which may improve the health of occupants, and some of which may increase the risk of infection. Many of the solutions offered are expensive.
This document, written from an evidence-based public health perspective, and published by Australia's leading engineering professional society for ventilation and air quality, is intended to address the many questions that school administrators have been and will be considering in order to provide appropriate guidance for creating a school setting where the focus can be on education, and not the building itself.
