Trifil Bus Shelter

Level 8

The Trifil Bus Shelter was my submission for the RSA Student Design Awards Competition (2020) in the 1st semester of my final year. The aim of the brief was to address air pollution and posed a question, “how might we ensure that everyone living in areas with poor air quality is guaranteed their right to clean air?” Due to their proximity, I focused on bus shelters, as they are prone to the build-up of vehicular exhaust emissions, and it is passengers waiting for the bus who suffer the most.

The main problem was how to deal with this pollution. How to stop it from reaching the customers? The general premise is that by controlling the airflow into these structures, and in and around the would-be passengers, the air quality can be improved substantially. Therefore, a number of filtration methods were included in the final design: vegetation barrier, activated carbon, and ionisation.
