In a pioneering initiative aimed at enhancing public awareness of environmental conditions, the municipality of Korydallos has introduced Greece's first pilot "smart bench" in the Eleftherias central square. Designed by scientists from the National Observatory of Athens in collaboration with the National and Kapodistrian University of Athens and Energy4Smart, these benches are equipped with state-of-the-art technology to monitor local air quality.
The concept behind these benches arose from a partnership formed under the framework of the Attica region's program promoting collaboration between innovative enterprises and research centers. Dr. Vasiliki Asimakopoulou, scientific director at the National Observatory of Athens, explains that the benches are strategically located in areas of high human activity, ensuring that their data reflects typical Athenian environmental profiles.
The "smart benches" are equipped with sensors that continuously monitor eight pollutants known to impact both the environment and public health. These pollutants include PM particles of various sizes, carbon monoxide, carbon dioxide, nitrogen dioxide, ozone, and sulfur dioxide. Real-time data collected by the benches is transmitted to the Observatory's database, where it undergoes automated quality checks before being displayed on one of the bench's two screens. This information is presented in a user-friendly format, indicating air quality levels such as "moderate," "good," or "bad," ensuring accessibility for all citizens.
"The main objective of the project is to democratize access to air quality information," asserts Dr. Asimakopoulou. "Unlike weather reports, which are widely accessible, information on air pollution has historically been less transparent. These smart benches aim to bridge that gap by providing systematic updates directly to the public."
Argyro Naziri, founder of Energy4Smart, highlights the durability and functionality of the benches, noting their energy autonomy through integrated photovoltaic panels and robust connectivity via Wi-Fi and a built-in microcomputer. This technological resilience addresses previous challenges such as power supply issues and vandalism, ensuring reliable operation in urban environments.
Beyond Korydallos, similar benches and "energy kiosks" have been deployed across other municipalities in the Attica region, including Vari – Voula – Vouliagmeni, Piraeus, and Kallithea. These installations not only monitor air quality but also offer amenities such as USB ports, Wi-Fi connectivity, and emergency messaging capabilities, enhancing community engagement and safety.
Funded by the Attica region's "Faircity" project under the Operational Programme Attica 2014-2020, this initiative exemplifies a forward-thinking approach to integrating technology with urban infrastructure. As Greece continues to prioritize environmental sustainability and public health, the expansion of these smart benches promises to empower citizens with vital information while fostering a cleaner, healthier urban environment.
