Online Modelling and Prefab Layout definition for building Renovation

This paper introduces a powerful semi-automated tool that efficiently creates detailed 3D building models and layouts of prefabricated modules with solar panels from building images and Open Street Map floor plans. The tool permits the generation of the existing building model and the layout of the prefabricated panels in an average of 25 minutes, depending on the complexity of the building geometry. The shape of the building and the number of solar panels that can fit on the building envelope are determined using the generated 3D models and layouts. With the use of prefabricated modules and solar panels, building upgrades can be made more affordable and energy-efficient.
