Sustainable Streetscapes: Design Approaches and Examples of Viennese Practice
Jürgen Furchtlehner; Daniela Lehner; Lilli Lička
Streets are ubiquitous and cater to various functions in a city. However, today most streets are unilaterally used and designed likewise. Car-centred spatial distribution is currently being questioned in the course of urban densification and in light of climate and ecological challenges. The presented work focuses on a multi-layered transformation of streetscapes towards a multi-purpose social and ecological space, which goes beyond a mere redistribution of space and functions. This paper draws from the results of an interdisciplinary research project headed by the Institute of Landscape Architecture (University of Natural Resources and Life Sciences, Vienna). The Viennese situation is aligned with international trends. The research includes comparative analysis of streetscapes in Vienna and comparable cities, literature reviews, collaborative workshops and qualitative interviews. As a result, progressive layout specifications and quality aspects for future streets are proposed and presented in extracts. Furthermore, the goal of green space social equity is linked. The paper concludes by arguing for comprehensive consideration and redesign of streetscapes as one promising puzzle to counteract the evident challenges of climate change in urban settings. Its range reaches from small scale microclimatic improvements up to citywide provision of accessible, useable, ecologically sound and sustainable public space with new standards for streets as potential backbone.
