Air Inverleith by team 4 Colours aimed to encourage the community to cycle and walk more by raising awareness about air quality in the neighbourhood. The more people walk or cycle, the better the air quality will become, resulting in healthier and more pleasant communities.
They used an online and paper survey to gather information about the perceptions and behaviours. Additionally, they discussed this with residents in different strategic public places and thereby gained an in-depth understanding of their perceptions and attitudes. In order to maximise the impact of our action, they asked Inverleith locals to install biodegradable light-blue balloons in front of their house as a sign to show that they care about air pollution.
Finally, they measured the levels of NO2 in key locations in Inverleith neighbourhood, using an innovative air sensor device developed by the Centre of Speckled Computing, School of Informatics, The University of Edinburgh. Based on the results, they installed a white 36″ biodegradable latex balloon in five of their chosen locations. In an attempt to make the invisible visible, they partially covered each balloon with black paint in a way that corresponded to the level of air pollution at the location in question. They created this installation to visualise and communicate their air quality measurements, in order to raise awareness and encourage reflection and discussion.
