The team of Óbuda University participated in a field measurement campaign in Osaka within the framework of the GreenQual project, closely linked to the professional programme of the workshop. The objective of the measurement activity was the comparative analysis of the microclimatic characteristics of different urban spatial typologies, with particular attention to the effects of spatial use, built density, and green infrastructure.

During the campaign, three locations with distinct characteristics were investigated: an urban square, a densely built narrow street, and a larger park area. Measurements were carried out on the first day in the square, and on the second day in the narrow street and the park. At each location, three repeated measurement cycles were conducted, each lasting 30 minutes, allowing for a more precise capture of short-term microclimatic dynamics in the given environments.

From Óbuda University, the fieldwork involved Dr. habil. Viktória Sugár, Dr. Zsuzsanna Fáczányi PhD, Prof. Dr. István Kistelegdi, Dr. Attila Kerekes PhD, Dr. Aurél Benárd DLA, Péter Kiss, Marcell Nánási, and Martin Kolman as researchers and lecturers. The work was carried out in close collaboration with colleagues from Osaka, who not only provided professional support but also significant assistance in transporting measurement equipment between sites and adapting to local conditions. This collaboration was essential for efficient data collection and the accurate implementation of measurement protocols.

The experiences gained during the campaign contribute to the comparative analysis of different urban situations and to a more precise understanding of the cooling effects of green areas and spatial design solutions. Differences between the sites were already clearly perceptible during fieldwork and can later be quantitatively validated through data processing and analysis.

The significance of the campaign also lies in enabling the validation and further development of measurement methodologies in an international context, under different climatic and urban structural conditions, thereby strengthening the generalisability and applicability of the research outcomes of the GreenQual project.

Lead researchers of the consortium:

Dr. Viktória Sugár from Óbuda University (European project leader), Prof. Michihiro Kita from Osaka University (Japanese project leader), Dr. Bálint Hartmann and Dr. Vera Iváncsics from F4STER, as well as Dr. Barbara Czesak and Dr. Renata Różycka-Czas from University of Agriculture in Kraków.

The project GreenQual: Investigating the role of green infrastructure in enhancing climate resilience and improving water, soil, and air quality in dense urban environments is jointly funded by the Concert-Japan programme of the European Interest Group (EIG) and the Hungarian National Research, Development and Innovation Office (NKFI) under grant agreement No. 2024-1.2.2-ERA_NET-2024-00006.
