Rooftop Activation Ontology: a semantic framework connecting rooftops, owners, urban challenges and incentives
Published in MultiRoofs, 2026
The post introduces the Rooftop Activation Ontology, a semantic framework developed as part of the MultiRoofs project to facilitate the identification and transformation of underused urban rooftops into multifunctional spaces. It provides a common vocabulary for describing rooftop characteristics, ownership structures, urban challenges and available policy incentives, allowing these elements to be connected and analysed systematically. The ontology classifies rooftops into seven activation categories, covering areas such as water management, green infrastructure, renewable energy, human activities, mobility and logistics. It also links rooftop opportunities to different owner types, local urban needs and financial or policy incentives. Overall, the framework aims to support researchers, urban planners and policymakers in identifying rooftop activation opportunities and promoting more sustainable, resilient and liveable cities.
