ParaSol - Multifunctional solar canopies for urban streets and places
A substantial part of our cities is utilized by areas of moving and stationary traffic. Particularly outdoor car parks are environmentally rather unfriendly and area-intensive. Not only do they seal the grounds and cause urban heat islands, they are almost always strictly monofunctional.
With the city of Leoben as a use case, the exploratory project examines the spatial effects, synergy- and energy potentials of newly developed wide-span light-weight solar canopies for streets and squares in urban public space as well as their implications on the cityscape and the city function. Municipal parking lots as well as intra-urban transit routes will be included in the exploration. The objective is to transform these deficient areas into functional and spatially valuable urban spaces.
The project serves the strategic and content-related preparation of a follow-up R&D demo project. This R&D project is intended to demonstrate the application of existing and new material and photovoltaic technologies or technology combinations in the city infrastructure in prototypes, including the material knowledge in the region with a focus on membrane, polymer and thin glass technologies, and lead to a marketable product development.
Based on an interdisciplinary basic assessment the general framework and potentials of urban space, urban function, material, construction and solar power were analysed and a methodical matrix of selection criteria for site evaluation was elaborated. Test designs for selected sites show different variations of form and use to be compared. To estimate solar potentials a simplified evaluation method has been developed especially. Results were presented to experts in a workshop to be critically discussed.
- interdisciplinary matrix and selection criteria of urbanistic and technical requirements and potentials for multifunctional urban solar canopies
- market overview of PV technologies
- simplified method for determining solar potentials
- solar potentials for basic form types and selected sites based on test designs
- transdisciplinary reconciled design-proposals for multifunctional solar-active roofs in urban open space
- roadmap for the subsequent R&D demo-project
The further processing of the topic as a R&D-demo-project was recommended in the expert workshop and is intended. Furthermore, numerous research questions could be phrased out for further projects.
