Megjegyzések:According to the Horizon 2020 climate and energy package, legislation has to meet the 20-20-20 target. That means that EU member countries have to reduce the amount of greenhouse gases by 20% to increase the proportion of renewable energy to 20% and to improve the energy efficiency by 20%. Our study is connected to renewable energy issues, the goal was to assess the extent of solar radiation exploitation potential of roofs in a typical Hungarian residential area. Our sample area (~1 km2) was in Debrecen, the second largest city in Hungary. An aerial Light Detection and Ranging (LiDAR) survey was conducted with the density of 10 points/m2. We extracted the buildings with the MicroStation TerraScan software and tested the geometry of them. The classification and vectorization of buildings were based on Terrascan semi-automatic algorithms in a Microstation environment. Primarily the roofs were important for us as these surfaces are the possible spaces for thermal and photovoltaic equipment. We determined the slope and aspect for each roof element and summarized the whole possible surface using the detected roof parts. Our research shows that the LiDAR Energy based survey of roof-exploitation for solar energy can be a good solution in a residential area, but we have to take into account some circumstances, e.g. the corrupted roof-geometries or numerous misinterpreted street furniture.

Megjegyzések:According to the challenge of the reduction of greenhouse gases, the structure of energy production should be revised and the increase of the ratio of alternative energy sources can be a possible solution. 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.
