Nature-based solutions use a holistic viewpoint to address social challenges while providing environmental, social and economic benefits simultaneously. The Victoria Quay is a historical space with complex social and environmental issues. This study uses an investigation-oriented method to explore the re-planning strategies. The environmental problems are addressed by extending the green infrastructure into the site to recover the ecological corridor and alleviate flooding risks. The originally single land-use type is changed, and several historical buildings are transformed into landmarks to improve the connection with city center by linking the ‘golden route’. All the proposed measures tried to reactivate the various relationships rather than merely renew the Victoria Quay.
This study focuses on exploring the impact of urban forms and vegetation combination patterns on the microclimate in a complex urban environment. Results shown that the closed urban form has higher air temperature resulting in pedestrians are easier to feel heat stress; instead, the open urban form usually has higher wind speed. Vegetation can effectively reduce wind speed while reducing the change rate of the mean radiant temperature. However, the effect on air temperature and humidity are most distinct in the morning. Trees and shrubs could improve the surrounding thermal comfort conditions by reducing heat stress, but this effect depends on the density of the leaf area. More importantly, study has not found that the ground cover plants contribute to the improvement of thermal comfort.
Brigittaplatz located in the 20th district of Vienna, which is a mixed culture residential community with various issues. This paper attempts to uncover the existing problems, weaknesses, potential opportunities of the site and explore a set of local interventions to accomplish site regeneration through architectural and landscape measures. Study utilizes two axes to improve and reconnect the public service, green corridor as well as the interactive relationship. All the proposed interventions are not merely public facility renewal but a new functional and social design, which is trying to reactivate the various relationships in the site that can enhance the quality of life and carry over the impact to larger scales. Authors seek a holistic approach to regenerate Brigittaplatz.
