Global Coalition Launches Initiative to Establish Universal Indoor Air Quality Standards: Global Open Air Quality Standards (GO AQS)

Sotirios Papathanasiou2 Comments

A diverse global coalition of scientists, air quality experts, and industry leaders has united to establish the Global Open Air Quality Standards (GO AQS), an unprecedented initiative aimed at creating universal indoor air quality (IAQ) standards. This groundbreaking effort seeks to ensure that everyone, regardless of location or socio-economic status, has access to the knowledge and tools needed to enhance their health and well-being through improved air quality.

GO AQS will serve as an authoritative and comprehensive resource for scientists, engineers, public health officials, businesses, and policymakers worldwide. By providing accessible, consistent and clear, standardised guidelines for IAQ, it empowers people to make informed decisions about their living and working environments, directly impacting health and productivity.

IAQ significantly affects our health, cognitive function, and overall productivity. Poor indoor air can exacerbate respiratory conditions, increase the risk of cardiovascular problems, and contribute to reduced work performance. Establishing universal air quality standards is a critical step in ensuring equitable access to clean and healthy air globally.

The coalition comprises experts from different fields including public health, environmental science, epidemiology, occupational health, engineering, and air quality research. Together, they are dedicated to developing GO AQS standards that are both scientifically robust and practical for implementation across diverse settings. These standards will address a wide range of indoor pollutants, including particulate matter (PM and PCN), carbon dioxide (CO2), carbon monoxide (CO), ozone (O3), and formaldehyde (CH2O), which are known to have significant adverse effects on human health and environment.

GO AQS aims to be a valuable tool for the public, private sector, and academia alike. Organisations that adopt these standards can enhance the health and well-being of their employees and customers, while simultaneously reducing their environmental footprint. This initiative also supports broader sustainability goals by promoting healthier indoor environments. 

While air quality interrogators and manufacturers are supportive of the overall goals of GO AQS, there are areas where the draft version requires further refinement to ensure its practical implementation. We remain committed to working collaboratively with all stakeholders to finalise a version of GO AQS that is both effective and feasible for the industry. Therefore the coalition is currently finalising the GO AQS standards and developing educational materials to facilitate their global implementation. The official launch is anticipated in December 2024, marking a significant milestone in the global effort to prioritise IAQ.

Over-the-Range Hood Microwaves: Addressing Indoor Air Quality Concerns

Sotirios Papathanasiou1 Comment

Over-the-range hood microwaves offer the convenience of a combined microwave and “ventilation” system. However, a common misconception is that they effectively remove cooking fumes and pollutants from the kitchen. While they do have a fan system, it’s crucial to understand their limitations.

Recirculation vs. True Ventilation:

Unlike range hoods that vent exhaust outdoors, most over-the-range microwaves utilize a recirculation system. This means they draw in cooking fumes, grease, and moisture through a metallic mesh filter with holes bigger than a Swiss cheese, then release the “treated” air back into the kitchen.

What is a Healthy Building? Why Indoor Air Quality is the Key?

Sotirios Papathanasiou3 Comments

Don’t be fooled, even the most outdoorsy person spends a great deal indoors. Apart from the fact that we spend a lot of time indoors because we are safe from the elements and other external threats, indoor environments are designed to meet other occupants’ needs like resting, being productive, or even having fun. A rule of thumb is to take your age and multiply it by 0.9. Vualá, that’s the time you have spent indoors so far.

Nowadays buildings are fully equipped with all sorts of things in an effort to make occupants’ life better, healthier, or even more creative. If we take as an example a modern house, we will find modern gym equipment, connected lights to create an atmosphere, smart vacuum cleaners, etc. If we take as an example an office building, we will find automation in the entrance with automated doors, fire alarms, elevators, etc.
