Roof Structure Extraction from Remote Sensing Images

Accurate roof structure extraction from aerial imagery is important for applications such as solar energy assessment, urban analysis, and 3D city modeling, where roof surfaces require geometrically reliable polygonal representations. Although instance segmentation methods can det...

Scenario-based energy simulation of tree planting strategies to reduce the heating and cooling demand of buildings under 2050 climate conditions

Abstract. Urban areas account for a large share of global energy use and emissions and face increasing climate- and heat-related challenges. These conditions drive the development of district-scale strategies such as Positive Energy Districts. Urban Building Energy Modelling (UBE...
