Best Practices for Urban Densification: A decision-making support process using microclimate analysis methods and parametric models for optimizing urban climate comfort

This paper presents an approach for microclimate aware densification of urban areas by creating best practices for an in situ application for block-size urban developments. The discussed procedure generates and evaluates urban block types according to microclimate criteria by integrating climate and comfort parameters in the design process of existing urban areas. It supports urban designers by generating design strategies that aim for climate, comfort and spatial as well as for urban design qualities. To achieve this, a multi-step method with different analysis and research processes has been set up. At the end, a parametric envelope tool was created for a local case study area by incorporating pre-defined design strategies built on previous investigations as urban design strategies. It is expected that this envelope tool can be transferred to similar urban development activities and guide microclimatic versus densification trade-offs. The presented approach can be applied from street canyon to block size urban situations.
