Photovoltaics portfolio analysis for the building and infrastructure roofs of the SBB

Project overview

The SBB owns and operates one of the largest building portfolios in Switzerland. Keeping an overview of more than 10,000 roof areas is a major challenge, and something that is only possible with automatic processes and algorithms. For a potential study, Basler & Hofmann developed a method that enables automated initial assessment of the roof areas.
