Abstract:

All over the world cities are growing with a shortage of resources. It is indispensable to implement transdisciplinary strategies for urban planning in order to develop attractive and eco-friendly environments. Therefore, with the case study of the Limmattal Region in Switzerland, the NRP65 SUPat project aims to integrate qualitative and quantitative design and research activities throughout collaborative urban planning processes and visualization-simulation tools. In this way, different regional future scenarios are evaluated and explored in order to proposed sustainable urban patterns for future developments.

The focus of this thesis is to contribute to the NRP65 project throughout a method proposal. This approach integrates climate and comfort parameters within the "envelope" theory, using environmental analysis tools (Autodesk Ecotect and Autodesk Vasari), and applying this into existing block typologies in order to obtain urban design strategies for the densification of cities. To achieve this, a series of steps had to be considered as analysis and research processes.

At the end, a final envelope was created for a local case study in Alt-stetten, Zurich (Residential focus area: Baslerstrasse- Grundstrasse - Frei-hofstrasse), which is the result of sustainable urban design strategies. This envelope works as a set of possible development areas for the densification of existing blocks. From this initial envelope, four different block designs were created for each future scenarios. With these four new variants, the idea was to make a loop and further simulate the environmental effects with Autodesk Ecotect and Autodesk Project Vasari, in order to evaluate the proposed method.

The general purpose of this method is to create a process, which combines environmental analysis tools with urban analysis and research procedures to survey on micro-climate friendly urban typologies.
