A unique site-responsive installation activated by the visitor’s presence, the gallery surroundings and the weather to monitor changes in the air quality and increase awareness for air pollution’s bioindicators.

Site-responsive installation

Volatile I (2024) is a unique site-responsive installation, reacting to visitors’ presences and the gallery’s environmental changes.

It is complemented with a series of air quality sensors that mimic the sentient activities of lichens. Having no roots and relying only on the natural elements – sun, air, and water – lichens truly are guardians of our environment, generating air quality bio-indicators.

Set up around the gallery, the sensors are programmed to measure the particulate matter in the air, CO2 or carbon dioxide, air quality index, volatile organic compounds, air pressure, temperature, and humidity present in the gallery.

Changes in the sensors’ measurements are dependent on the audience’s interactions with the space, and other factors, such as the weather and nearby road traffic during the three-week period of the exhibition.

The graphs shown on the micro computer’s displays are visual representations of the invisible changes in the air in real time.
