Kawaiicon Implements CO2 Monitoring System Amid Health Concerns

Kawaiicon, a prominent hacker conference held at the Michael Fowler Centre in Wellington, New Zealand, faced significant public health challenges due to ongoing outbreaks of measles, COVID-19, influenza, and RSV. In response, the event organizers took proactive measures to monitor indoor air quality, specifically focusing on carbon dioxide (CO2) levels, which are known to impact cognitive function and facilitate the transmission of airborne viruses.

The venue's existing HVAC system, which utilizes MERV-8 filters, was deemed insufficient for optimal air quality, prompting Kawaiicon organizers to seek innovative solutions. They noted that the venue's age limited their ability to control air flow effectively. To address these concerns, the organizers deployed 13 RGB Matrix Portal Room CO2 Monitors, a project adapted from Adafruit Industries, which provided real-time data on CO2 levels throughout the conference.

The implementation of the CO2 monitoring system began a month prior to the event, with collaboration from researchers at the University of Otago's public health department. The monitors were connected to an internet-accessible dashboard, allowing attendees to view live readings and historical data on CO2 trends in various spaces within the venue. This initiative aimed to empower attendees with critical public health information, enabling them to make informed decisions regarding their participation in the event.

Limor “Ladyada” Fried, founder of Adafruit, praised the conference's efforts, highlighting the importance of equipping individuals with the skills to monitor air quality effectively. The strategic placement of the monitors was crucial, with devices installed in key areas such as the Main Auditorium, Renouf session space, daycare, and Quiet Room, ensuring comprehensive coverage throughout the venue.

Kawaiicon's approach to air quality monitoring reflects a broader commitment to community health and safety. A spokesperson for the event, known as Sput, emphasized that the considerations for air quality were akin to other accessibility measures typically addressed at conferences. The tech-savvy nature of the Kawaiicon community facilitated the setup of the monitoring system, showcasing how accessible CO2 monitoring technology can be for similar events.

While the initiative received praise for its innovation, some critics argue that reliance on CO2 levels alone may not fully address the complexities of indoor air quality and pathogen transmission. Concerns have been raised about the adequacy of the existing HVAC systems in venues like the Michael Fowler Centre, suggesting that more comprehensive solutions are necessary to ensure attendee safety.

• “That’s awesome,” says Adafruit founder and engineer Limor “Ladyada” Fried about the conference’s adaptation of the Matrix Portal project. “The best part is seeing folks pick up new skills and really understand how we measure and monitor air quality in the real world (like at a con during a measles flare-up)!”

• “To be honest, it is no different than having to consider other accessibility options (e.g., access to venue, access to talks, access to private space for personal needs),” — Sput, Kawaiicon spokesperson.
