Potentials and Limits of Photovoltaic Systems Integration in Historic Urban Structures: The Case Study of Monument Reserve in Bratislava, Slovakia

In the context of current energy crisis and climate change, importance discussions on how to incorporate monument protection into sustainable strategies that mitigate human impact environment implement renewable sources while preserving cultural values is raised. Through case study Monument Reserve in Bratislava, Slovakia, this article presents potentials limits integration photovoltaic systems historic urban structures directly affect their feasible participation smart city positive district concepts by means cooperativeness. This highlights most recommendations basic principles assess visual select appropriate solutions. Using datafication process, it analyzes irradiance pitched flat roof polygons set area based characteristics such as normal vector azimuth slope rooftops. For purpose, a 3D morphological model LOD3 detail open-source solar irradiation r.sun implemented GRASS GIS / QGIS were used. The data obtained provided an estimate output potential endow city’s power grid compared electricity consumption particular district. Furthermore, these are suitable for designing customized technical aesthetic solution photovoltaics with respect sustainability, well decision- policy makers.
