Redistribution of the energy production to the private houses is an alternative of large power stations at least in a partial manner. Especially, the utilization of solar energy represents a real possibility to exploit the natural resources in a sustainable way. In this study we attempted to survey the roofs of the buildings with an automatic method as the potential surfaces of placing solar panels. A LiDAR survey was carried out with 12 points/m2 density as the most up-to-date method of surveys and automatic data collection techniques. Our primary goal was to extract the buildings with special regard to the roofs in a 1 km2 study area, in Debrecen. The 3D point cloud generated by the LiDAR was processed with MicroStation TerraScan software, using semi-automatic algorithms. Slopes, aspects and annual solar radiation income of roof planes were determined in ArcGIS10 environment from the digital surface model. Results showed that, generally, the outcome can be regarded as a roof cadaster of the buildings with correct geometry. Calculated solar radiation values revealed those roof planes where the investment for photovoltaic solar panels can be feasible.}, year = {2015}, eissn = {2063-4269}, pages = {11-17}, orcid-numbers = {Fazekas, István/0000-0001-7973-9454; Szabó, Szilárd/0000-0002-2670-7384} } @article{MTMT:2802190, title = {Utilization of solar energy potential on roofs: building extraction from the LiDAR database in a Hungarian sample area}, url = {https://m2.mtmt.hu/api/publication/2802190}, author = {Szabó, Gergely and Szabó, György Emőd and Enyedi, Péter and Fazekas, István and Buday, Tamás and Kerényi, Attila and Paládi, Mónika and Mecser, Nikoletta and Szabó, Szilárd}, journal-iso = {WIT TRANSAC ECOL ENVI}, journal = {WIT TRANSACTIONS ON ECOLOGY AND THE ENVIRONMENT}, volume = {186}, unique-id = {2802190}, issn = {1746-448X}, year = {2014}, eissn = {1743-3541}, pages = {197-205}, orcid-numbers = {Fazekas, István/0000-0001-7973-9454; Szabó, Szilárd/0000-0002-2670-7384} } @article{MTMT:2799908, title = {The carbon footprint of a biogas power plant}, url = {https://m2.mtmt.hu/api/publication/2799908}, author = {Szabó, György Emőd and Fazekas, István and Szabó, Szilárd and Szabó, Gergely and Buday, Tamás and Paládi, Mónika and Kisari, Krisztián and Kerényi, Attila}, doi = {10.30638/eemj.2014.322}, journal-iso = {ENVIRON ENG MANAG J}, journal = {ENVIRONMENTAL ENGINEERING AND MANAGEMENT JOURNAL}, volume = {13}, unique-id = {2799908}, issn = {1582-9596}, year = {2014}, eissn = {1843-3707}, pages = {2867-2874}, orcid-numbers = {Fazekas, István/0000-0001-7973-9454; Szabó, Szilárd/0000-0002-2670-7384} } @article{MTMT:2794375, title = {Annual pattern of the coefficient of performance considering several heat pump types and its environmental consequences}, url = {https://m2.mtmt.hu/api/publication/2794375}, author = {Buday, Tamás and Szabó, György Emőd and Fazekas, István and Paládi, Mónika and Szabó, Szilárd and Szabó, Gergely and Kerényi, Attila}, doi = {10.1556/IRASE.5.2014.2.10}, journal-iso = {INT REV APPL SCI ENG}, journal = {INTERNATIONAL REVIEW OF APPLIED SCIENCES AND ENGINEERING}, volume = {5}, unique-id = {2794375}, issn = {2062-0810}, year = {2014}, eissn = {2063-4269}, pages = {173-179}, orcid-numbers = {Fazekas, István/0000-0001-7973-9454; Szabó, Szilárd/0000-0002-2670-7384} } @{MTMT:2789301, title = {A biomassza és a földhő energetikai felhasználásának környezeti hatásai}, url = {https://m2.mtmt.hu/api/publication/2789301}, author = {Kerényi, Attila and Szabó, György Emőd and Szabó, Szilárd and Fazekas, István and Buday, Tamás and Szabó, Gergely and Paládi, Mónika}, booktitle = {Fenntartható energetika megújuló energiaforrások optimalizált integrálásával}, unique-id = {2789301}, year = {2014}, pages = {203-236}, orcid-numbers = {Szabó, Szilárd/0000-0002-2670-7384; Fazekas, István/0000-0001-7973-9454} } @article{MTMT:2787657, title = {Testing of algorithms for the identification of asbestos roofing based on hyperspectral data}, url = {https://m2.mtmt.hu/api/publication/2787657}, author = {Szabó, Szilárd and Burai, Péter and Kovács, Zoltán and Szabó, György Emőd and Kerényi, Attila and Fazekas, István and Paládi, Mónika and Buday, Tamás and Szabó, Gergely}, doi = {10.30638/eemj.2014.323}, journal-iso = {ENVIRON ENG MANAG J}, journal = {ENVIRONMENTAL ENGINEERING AND MANAGEMENT JOURNAL}, volume = {143}, unique-id = {2787657}, issn = {1582-9596}, abstract = {There are several environmental issues in urban areas that are caused by the unintentional consequences of past activities. One of these issues is the wide application of asbestos cement in roofing materials in the 2nd half of the 1900s. In this study, our goal was to identify different roof types and to determine those with asbestos components using high-ground (1 m) and spectral (126 bands) resolution airborne hyperspectral imagery (AISA Eagle II) and several classification approaches. In addition, we aimed to identify those wavelengths that play a significant role in distinguishing the different roof types. In the image analysis, the SAM, MLC and SVM classification methods were used to evaluate the different types of roofs. These methods resulted in accurate maps of the roof types, and asbestos cement roofs were identified with over 85% accuracy.}, year = {2014}, eissn = {1843-3707}, pages = {2875-2880}, orcid-numbers = {Szabó, Szilárd/0000-0002-2670-7384; Fazekas, István/0000-0001-7973-9454} } @article{MTMT:2787648, title = {Napenergia-potenciál automatizált felmérése Debrecen példáján}, url = {https://m2.mtmt.hu/api/publication/2787648}, author = {Szabó, Gergely and Szabó, György Emőd and Enyedi, Péter and Fazekas, István and Buday, Tamás and Kerényi, Attila and Paládi, Mónika and Mecser, Nikoletta and Szabó, Szilárd}, journal-iso = {FÖLD ÉS EMBER}, journal = {FÖLD ÉS EMBER}, volume = {6}, unique-id = {2787648}, issn = {1585-5465}, year = {2014}, pages = {21-29}, orcid-numbers = {Fazekas, István/0000-0001-7973-9454; Szabó, Szilárd/0000-0002-2670-7384} } @inproceedings{MTMT:2755111, title = {Annual pattern of the coefficient of performance considering several heat pump types and its environmental consequences}, url = {https://m2.mtmt.hu/api/publication/2755111}, author = {Buday, Tamás and Szabó, György Emőd and Fazekas, István and Paládi, Mónika and Szabó, Szilárd and Szabó, Gergely and Kerényi, Attila}, booktitle = {Proceedings of Denzero International Conference}, unique-id = {2755111}, year = {2014}, pages = {123-131}, orcid-numbers = {Fazekas, István/0000-0001-7973-9454; Szabó, Szilárd/0000-0002-2670-7384} } @inproceedings{MTMT:2755085, title = {Lidar based assessment of roofs.
