Elevated ranges of CO2 result in diminished cognitive capacity and facilitate transmission of airborne viruses, which might linger in poorly ventilated areas for hours. The extra CO2 within the air, the extra virus-friendly the air turns into, making CO2 information a useful proxy for tracing pathogens. In actual fact, the Australian Academy of Science described the air pollution in indoor air as “another person’s breath backwash.” Kawaiicon organizers confronted working a big infosec occasion throughout a measles outbreak, in addition to always rolling waves of Covid-19, influenza, and RSV. It’s a well-known ache level for convention organizers annoyed by large gaps in public well being—and lack of management over their venue’s clear air requirements.
“Usually, the Michael Fowler venue has a single HVAC system, and makes use of Farr 30/30 filters with a score of MERV-8,” Kawaiicon organizers defined, referencing the filtration selections within the house the place the conference was held. MERV-8 is a budget-friendly alternative–commonplace observe for houses. “The toughest a part of the entire course of is being restricted by what the venue gives,” they defined. “The venue is older, which implies much less tech to manage air move, and an older HVAC system.”
Kawaiicon’s work started one month earlier than the convention. In early October, organizers deployed a small fleet of 13 RGB Matrix Portal Room CO2 Displays, an ambient carbon dioxide monitor DIY venture tailored from US electronics and equipment firm Adafruit Industries. The screens have been related to an internet-accessible dashboard with stay readings, day by day highs and lows, and information historical past that confirmed attendees in-room CO2 tendencies. Kawaiicon examined its CO2 screens in collaboration with researchers from the College of Otago’s public well being division.

“That’s superior,” says Adafruit founder and engineer Limor “Ladyada” Fried concerning the convention’s adaptation of the Matrix Portal venture. “The very best half is seeing of us choose up new abilities and actually perceive how we measure and monitor air high quality in the actual world (like at a con throughout a measles flare-up)! Hackers and makers are in a position to be self-reliant with regards to their public-health data wants.” (For the total specs of the Kawaiicon construct, you may take a look at the GitHub repository right here.)
The Michael Fowler Centre is a spectacular mix of Scandinavian brutalism and inside woodwork designed to boost sound and air, together with two grand pou—carved Māori totems—subsequent to the primary entrance that rise by way of to the higher foyers. Its cathedral-like acoustics posed a problem to Kawaiicon’s air-hacking crew, which they solved by putting the RGB screens in stereo. There have been two on every stage of the Principal Auditorium (4 complete), two within the Renouf session house on stage 1, plus screens within the daycare and Kuracon (children’ hacker convention) areas. To prime it off, screens have been positioned within the Quiet Room, on the Registration Desk, and within the Inexperienced Room.
“The issues we needed to take into account have been typical well being and security, and efficient placement (respiratory top, a number of screens for a number of areas, not close to home windows/doorways),” a Kawaiicon spokesperson who goes by Sput on-line instructed WIRED over e-mail.

“To be sincere, it’s no completely different than having to contemplate different accessibility choices (e.g., entry to venue, entry to talks, entry to personal house for private wants),” Sput wrote. “Being a tech-leaning group it’s simpler for us to get this arrange ourselves, or with volunteer assist, however undoubtedly not out of attain given how accessible the CO2 monitor tech is.”
Kawaiicon’s attendees might rapidly verify the circumstances earlier than they arrived and resolve find out how to defend themselves accordingly. On the occasion, WIRED noticed attendees checking CO2 ranges on their telephones, masking and unmasking in several convention areas, and watching a show of all room readings on a dashboard on the registration desk.
