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.
