Dr. habil Viktória Sugár and Martin Kolman represented Óbudai Egyetem at the 4th Ybl Conference on the Built Environment, presenting the latest research results and international collaborations related to the GREENQUAL project.

Both researchers contributed as speakers to the conference program. Martin Kolman delivered a Hungarian-language presentation focusing on urban microclimate measurement campaigns and simulation methodologies, while Dr. habil Viktória Sugár gave an English-language presentation introducing the long-standing research cooperation between Osaka University and Obuda University, as well as the broader international scientific framework of the GREENQUAL project.

Martin Kolman’s presentation focused on on-site measurement campaigns conducted in Budapest, Kraków, and Osaka to investigate urban heat island effects and the microclimatic behavior of different urban spatial typologies. Urban squares, narrow streets, and park areas were analyzed using standardized methodologies measuring air temperature, relative humidity, wind speed, and wind direction. The collected data provide a strong basis for validating and calibrating urban microclimate simulation models.

The presentation also highlighted the relationship between field measurements and ENVI-met simulations, emphasizing the influence of urban morphology, shading conditions, and green infrastructure on local microclimate and outdoor thermal comfort.

In her presentation, Dr. habil Viktória Sugár introduced the research partnership between Osaka University and Óbudai Egyetem, active since 2008, focusing on sustainable urban development, climate adaptation, and historic urban fabric research. The talk also presented the international structure of the GREENQUAL project, including GIS-based analysis, UBEM approaches, urban health investigations, and green accessibility research.

The GREENQUAL project is implemented through the cooperation of Óbudai Egyetem, Osaka University, University of Agriculture in Krakow, and F4STER Future 4 Zrt., aiming to develop innovative green infrastructure solutions supporting climate-resilient and healthier urban environments.
