This paper presents the outcome of a study based on the early-stage analysis of six virtual urban-scale designs located in Bern, Switzerland. A preliminary solar potential evaluation methodology is devised, inspired by previous studies, to allow the comparison of the projects’ potential for exploiting solar energy through passive (e.g. daylight) and active (e.g. photovoltaic) measures. The workflow employed distinguishes itself by integrating and confronting conflicting performance indicators and geometrical parameters. Findings show diversity in the performance among the different designs, while also highlighting the need to review the definition of urban solar potential and refine its assessment.
