EUGEO – ASSOCIATION OF GEOGRAPHICAL SOCIETIES IN EUROPE 79TOWARDS CLIMATE CONSCIOUS URBAN DESIGN – DEVELOPING A SYSTEM OF PLANNING CRITERIA IN HUNGARYAuthors: Flóra Szkordilisz*, Budapest University of Technology and Economics, Hungary; Lilla Égerházi; Tamás Gál, Dep. of Cli-matology and Landscape Ecology, University of Szeged, Hungary; Ágnes Gulyás; Márton Kiss, University of Szeged, HungaryKeywords: climate conscious urban design, envi-met, planning criteria, public space development Abstract: Urban microclimate has been afashionable topic in the last decade to involve quite a few researchers. Many havecome to the conclusion that green surfaces are essential in achieving a climate-conscious urban environment. Apart from greenerythere are also quite a few good and usable tools in order to improve urban microclimate such as solar sails, water surfaces,permeable paving, etc. It has come so far to facing also the question how urban planners can be helped by researchers to use ineveryday planning routine the results of theoretical researches. In the new programming period of the European Union (2014-2020), the novel system of planning and funding gives the opportunity to implement the interests of climate conscious urbandesign. One of the main challenges urban planners and architects will have to face is to trigger a way of planning methodology inorder to create an urban environment which can handle current climatic problems.In our work we present the 3rst version of a targeted indicator system, which can be used as planning criteria in the EU-funded urban public space development processes.4e main tool of our research was the ENVI-met model, which enables the quantitative comparison of the microclimatologicale7ects of the usable interventions and their indicators. 4e results highlight the outstanding importance of trees among thepossible solutions, and the need for integrated solutions with regard on every aspect of climate sensitive design.INTRA-URBAN CLIMATE OBSERVATIONS IN TWO CENTRAL EUROPEAN CITIESBASED ON ONE YEAR NETWORK DATASETSAuthors: Nóra Skarbit*, University of Szeged, Magyarország; János Unger, Dep. Climatology and Landscape Ecology, University ofSzeged, Hungary; Tamás Gál, Dep. of Climatology and Landscape Ecology, University of Szeged, Hungary; Stevan Savic, Clima-tology and Hydrology Research Centre, Faculty of Science, University of Novi Sad, Serbia4is study introduces urban climate monitoring systems implemented in Szeged, Hungary and Novi Sad, Serbia in 2014 and analyzesthe 3rst datasets of 2014-2015. In order to ensure a representative number and placement of stations, the selection of measurement siteswas based on Local Climate Zone (LCZ) maps developed for both cities. During the processing of the incoming data (air temperatureand relative humidity, as well as global radiation and wind speed) a human comfort index (Psychologically Equivalent Temperature) iscalculated from these parameters with a neural network method, and the measured and calculated parameters are interpolated linearlyinto a regular grid with 500 m resolution. As the results show the largest intra-urban thermal di7erences between the LCZ areas occurin the nocturnal hours reaching even 5ºC. In the spatial distribution of human comfort conditions there are distinct di7erences in thestrength of the loading between the neighbourhoods during the daytime. Overall, it can be stated that the monitoring networks are ableto provide bene3cial information for urban climate research and for the wider audience, too. 4ey record data with proper spatial andtemporal resolution and the accuracy of the sensors is satisfactory. Based on our evaluation the site selection was successful, as the tem-perature has di7erent characteristics at sites with di7erently classi3ed environment. 4e planned operation time of networks is minimum3ve years so the available long data series will provide an opportunity to perform spatially and temporally very detailed climatologicalinvestigations in relation to urban environment.EVALUATION OF OUTDOOR THERMAL COMFORT IN URBAN TRANSFORMATIONS OF NOVI SAD (SERBIA)Authors: Stevan Savic*, Climatology and Hydrology Research Centre, Faculty of Science, University of Novi Sad, Serbia; IvanaBajsanski; Dragan D Milošević, Climatology and Hydrology Research Centre, Faculty of Science, University of Novi Sad, TrgDositeja Obradovića 3, 21000 Novi Sad, SerbiaKeywords: algorithm, grasshoppers program, Novi Sad, Serbia, thermal comfort Abstract: 4e automated calculation method for the outdoor thermal comfort calculation at di7erent locations at street level ispresented in Novi Sad (Serbia), as an example. With this automated calculation procedure - past, present and future state of thethermal environment in the urban transformations was calculated and compared. Our calculations are based on the usage ofGrasshoppers program in which the algorithm was created and Universal 4ermal Climate Index (UTCI) was calculated. 4isnew approach provides faster acquisition of the results, detailed options for parameters input and numerous options for thegraphical representation of the results. Application of this procedure can provide signi3cant insight into the changes of thethermal environment as a consequence of urbanization that have to be taken into account in order to provide a lively urban envi-ronment for its residents.ABSTRACTS –P03
