Navigating the Post-Pandemic Landscape of Indoor Air Quality
A conversation with Professor Catherine Noakes
Cath is a chartered mechanical engineer with a background in fluid dynamics.
She is the Pro-Dean for Research and Innovation for the Faculty of Engineering and Physical Sciences at the University of Leeds where she leads research into ventilation, indoor air quality and infection control in the built environment using experimental and modelling-based studies.
From April 2020-22 she was a participant in the UK Scientific Advisory Group for Emergencies (SAGE), where she co-chaired the Environment and Modelling Group sub-focusing on the science underpinning environmental transmission of COVID-19.
She has also contributed to numerous advisory and working groups including with WHO and as part of the working group for the Royal Academy of Engineering work on Infection Resilient Environments.
In 2021 she was awarded an OBE for her contribution to the COVID-19 pandemic response and in 2023 she was awarded the Royal Society Gabor medal for her contribution to interdisciplinary science in understanding transmission of infection.
Our discussion, set against the backdrop of the COVID-19 pandemic, shed light on the evolving understanding of indoor environments and charted a path for future endeavors in air quality improvement.
The Unprecedented Spotlight on Indoor Air Quality
Cath articulated how the pandemic has thrust indoor air quality and ventilation into unprecedented focus. This surge in awareness, spanning public discourse to scientific exploration, marks a critical shift in how we perceive and prioritize the air within our buildings. The dialogue around ventilation, once a peripheral concern, has now ascended to the forefront of public health discussions, symbolizing a paradigm shift in our collective consciousness.
However, this enlightenment also underscored a critical void in our understanding of ventilation efficacy across the built environment, revealing a stark lack of comprehensive data on building ventilation standards and compliance.
Bridging the Knowledge Gap: From Awareness to Implementation
Highlighting the journey from heightened awareness to tangible action, she pointed out the intrinsic challenges in bridging this gap. The realization that many buildings significantly lack adequate ventilation strategies has prompted a call to action for regulatory reforms and a push towards compliance with established ventilation standards.
This pivot underscores the need for a holistic approach that transcends technological fixes, advocating for systemic changes in building design, maintenance, and regulatory oversight.
Air Cleaning Technologies: A Critical Evaluation
Our conversation took a nuanced look at air cleaning technologies. While acknowledging their potential in reducing airborne pathogens, Professor Noakes emphasized the importance of context-specific applications. The effectiveness of these technologies can vary dramatically, necessitating a careful evaluation of their use in different environments.
Moreover, the lack of standardized testing and regulation for air cleaners presents a challenge in ensuring their efficacy and safety. The call for standards and real-world efficacy studies stands out as a crucial step toward integrating air cleaning technologies into our broader strategy for indoor air quality management.
The Future of Indoor Air Quality: A Multifaceted Approach
Looking towards the horizon, Cath advocated for a multifaceted approach to improving indoor air quality. This includes harnessing the power of interdisciplinary research, integrating technological advancements with behavioural science, and grounding interventions in robust scientific evidence.
The concept of an indoor air quality observatory emerged as a beacon of hope, promising to provide a comprehensive database that could inform policy decisions, guide effective interventions, and ultimately improve public health outcomes.
Redefining Indoor Environments: A Call for Global Action
As we reflect on the lessons learned from the pandemic, it becomes evident that the path to healthier indoor environments requires sustained attention and action. The global health crisis, while a catalyst for change, has laid bare the complexities of ensuring safe and healthy indoor spaces.
This calls for an unwavering commitment to research, policy-making, and public education, aimed at fostering environments that support well-being and prevent disease transmission.
