The aim of the project is to provide a “proof of concept” of a control loop and tool set for the management, optimization and evaluation of green and climate-sensitive urban (district) planning.
The tool set consists of urban and open space planning instruments as well as climate simulations at different scale levels.
Starting point and motivation
Urban growth and the increasing density in urban areas put urban green infrastructure under pressure and lead to their loss. Climate change is intensifying the so-called urban heat island effect (UHI) and has negative impacts on cities and their residents, their quality of life and health. Numerous studies have shown that urban green (and blue) infrastructure can make a decisive contribution towards reducing this heat load.
Content and goals
The overall objective of the project “Green and Resilient City” is the reduction of the UHI effect in existing and future city quarters by optimizing the implementation of green infrastructure. The project has four main objectives:
1. A “proof of concept” of a control loop and tool set for the regulation, improvement and evaluation of green and climate-sensitive urban (district) planning – including a green and open space factor as an urbanistic index and planning tool, the GREENPASS® as an optimization tool for the microclimatic effects of green infrastructure on the plot and district level, the MUKLIMO_3 Stadtklimamodell as an evaluation tool for the mesoclimatic effects on urban level as well as Cosmo-CLM as a regional climate simulation model;
2. Visualization, assessment and adjustment of the climatic effects and sociocultural ecosystem services of different urban green infrastructure in the green and open space factor as well as in the different climate models and simulations;
3. Development of a procedure for the harmonization of the instruments and models as well as clarification of the interfaces of the climate models and of the opportunities for planning.
4. Testing and evaluating the tool set using two case studies to analyze the different areas of application of the tool set for green and climate-friendly urban (district) planning.
Based on two quarters in Vienna – urban renewal area: Innerfavoriten / Kretaviertel in the 10th district; urban extension area: aspern Seestadt in the 22th district – the feasibility and effectiveness of the tool set for the development of green quarters are examined.
Qualitative and quantitative methods are used to deal with the four central objectives in the project. Central to this is the investigation of the interfaces between regional climatic models (vulnerabilities) and microclimatic object planning for green infrastructure (GREENPASS®) as well as urban planning and open space planning tools.
It is to be investigated how interfaces between the different methods and models have to be organized, in order to be able to represent the actual situation as well as the future climate situation on district level in Vienna.
The possibilities for an implementation in administration are examined and discussed with employees of various departments of the city council of the city of Vienna (Advisory Board including Stadtbaudirektion der Stadt Wien, Wiener Umweltanwaltschaft, MA 18 – Stadtentwicklung und Stadtplanung). An exchange platform (eg Graz, Salzburg) is set up to check the transferability to other cities.
Based on this project a “proof of concept” of a method and a set of tools will be field-tested. This allows scientific justifications for urban planning decisions, which can be verified by the combination of the green and open space factor with the climatic models, and finally makes target fulfillment measurable.The project “Green and Resilient City” will create the first multiscale city planning tool set for green and climate-friendly city (district) planning.
