HeatResilientCity (HRC)

Heat resilient development of cities and urban districts - knowledge generation with a focus on local residents and implementation in Dresden and Erfurt (10/2017-01/2021)

Leibniz Institute of Ecological Urban and Regional Development, Dresden

The Leibniz Institute of Ecological Urban and Regional Development (IOER) is an establishment of the Leibniz Association for research in the spatial sciences. Our concern is the scientific basis for the sustainable development of cities and regions in the national and international context. Our research addresses ecological issues of sustainable development.
We investigate interactions between the natural environment and society and the options available for influencing them. On the basis of our findings we are able to advise the government and society. Our endeavor is to contribute through innovative research and advice to the compatibility of human action and the development of the natural environment in order to ensure the sustainable basis of life. The Institute addresses the scientific basis for the sustainable development of cities and regions in the national and international context. Researches are concentrated on six main areas, of which two collaborate in the HeatResilientCity project: The 'Environmental Risks in Urban and Regional Development' research area that deals with environmental risks caused by natural hazards and climate change as well as with the respective measures, strategies and tools required for taking these challenges into account, and the 'Landscape Change and Management' research area analyzing the changes in cities and regions with special consideration of open spaces and their ecosystem services

Main tasks of the IOER in the HeatResilientCity project:

The IOER serves as the lead partner and manager of the joint transdisciplinary research project, which necessitates co-design of the various sub-tasks, whereby the contents, goals and work processes closely reflect the practical requirements, potentials and windows of opportunity. The project management that strives for cooperation and the intelligent division of tasks includes the following core elements: (a) the joint discussion and management of the main research questions and their interlinking by a project steering group with equal voting rights for representatives from the fields of science and practice; (b) the provision and moderation of suitable formats for information and communication at the project level; (c) the continual supervision of planning and negotiation process in the neighborhoods (example quarters serving as living labs) as well as (d) risk management on the basis of wide experience gained in collaborative projects with complex and demanding constellations of partners. Further, IOER plays a leading role with regard to adaptation measures at building and city quarter scale including ecosystem services and the integrative consolidation of the research results of the joint transdisciplinary research project. At building scale, the IOER analyzes the effect of long lasting heat periods on and in buildings as well as measures for adaptation against summer heat for buildings. Based on that we develop precise concepts to protect buildings against summer heat. The intended measures must also be accepted by the residents. We transfer these concepts namely for prefabricated buildings and buildings in the Wilhelminian style, into recommended actions by the local project and associated partners. Combining climate protection (energy efficiency/green buildings) and climate adaptation measures (risk management) for buildings is thereby a major challenge. At the city quarter scale, we consider mainly so called ecosystem services. Thus, we examine in detail the value and functioning of nature for humans in the example quarters. The services of nature are very important for the well-being of residents because they allow for example temperature reduction during heat periods or the prevention of air pollution. The novelty value of the research is the high spatial resolution of the detection of ecosystem services and the multi-criteria assessment of their impacts.

Institute of Urban Research, Planning and Communication of the University of Applied Sciences in Erfurt

At the Institute of Urban Research, Planning and Communication (ISP), scientists from diverse disciplinary backgrounds are collaborating to investigate urban transformative processes. ISP’s main research fields range from housing and urban development, sustainable city and settlement planning, climate mitigation and adaptation to communicative participatory planning and governance.

Research at ISP is based on the concept of sustainability and integrates economical, ecological, social and cultural aspects in an intergenerational perspective. The research considers societal change and its effects on urban transformation, development and planning. Issues such as globalization, demographic change, information society, new forms of management (Good Governance) as well as administrative modernizations (New Public Management) are part of scientific investigations. More information is provided here.

Main tasks of the ISP within the research project HeatResilientCity

Within the joint research project, ISP plays a leading role with regard to governance structures, stakeholder perspectives and strategies for districts affected by heat. Perspectives of various actors on urban climate adaptation are investigated and analyzed. Besides participants from administrative, economic and civil sectors, also local residents are actively included in a transdisciplinary approach. In two example quarters in the state capitals Dresden and Erfurt, views of locals are collected, participatory events and activities are implemented and scientifically evaluated.

Tasks comprise inter alia:

  • inquiry of subjective heat stress, behavioral patterns and needs of local residents in both example districts 'Erfurt-Oststadt' and 'Dresden-Gorbitz' by surveys and mental maps;
  • stakeholder and network analysis to identify the perspectives of key actors on local climate adaptation processes, their capacity to take action as well as communication and implementation barriers. By comparing those results with the perspectives of local residents, interfaces can be identified;
  • planning, organization and implementation of events, activities enhancing knowledge transfer and public relations within the example quarters 'Erfurt-Oststadt' and 'Dresden-Gorbitz';
  • analysis of national and international good practices regarding citizen-oriented climate adaptation measures. Based on this analysis, success factors as well as barriers to feasibility, efficiency and acceptance of strategies can be identified and transferable experiences gained;
  • organization of experts' workshops and a concluding supra-regional conference, as well as evaluation and critical reflection of measures within the test districts;
  • documentation of climate adaptation approaches and their prioritization based on the residents' perspective, compilation of discrepancies and consensus between users, planners and experts.

The results will be presented in form of recommendations for municipal action as well as aggregated maps of both test districts, which integrate the different research approaches.

Technical University Dresden, Department of Meteorology

The climate system with its manifold interactions and feedbacks does not easily support single process oriented approaches. However, process understanding remains the key to understand nature through analysis and model building. The common research mission at the Department of Meteorology is the “Surface- Atmosphere-Interaction” with the necessary, i.e. microscale to mesoscale resolution.

Both long-term observations and intensive measurement campaigns are realized in order to collect a multitude of three-dimensional atmospheric data sets. Modeling and model simulations of the atmosphere, including interactions with the land surface (e.g., vegetation), are used within research projects. The topics of the HRC project are integrated in the research focus of bioclimate and urban climate, generating synergies with other collaborative projects (3DO, Life Local Adapt, Urban Forests). In the last ten years, the scope of the Department of Meteorology at the TU Dresden was considerably enlarged. Nevertheless, research and teaching remain equally important tasks of all approx. 30 members of the Department. Thus, current research results are used for lectures and traineeships in the study programs at the TU Dresden (including hydro sciences, forest sciences, geography, spatial development and natural resource management).

Main tasks of the TUD in the HeatResilientCity project

The sub-project of TU Dresden aims to identify and quantify factors for the current and future thermal stress in specific districts of the cities of Dresden and Erfurt. Climate data from the regional (ca. 3 km) to small scale (buildings) will be provided as a main project result – for users in the joint project and for later applications on district level. For this purpose, data from the dynamic mesoscale model Cosmo-CLM (German Weather Service) and regionalized station-based data (REKIS) will be reprocessed for periods in present (1981-2010, reanalysis data ERA-Interim) and future (2021-2050, IPCC RCP 8.5) for the cities Dresden and Erfurt. Based on these data, grid-based mean and extreme reference summer periods for past, present and future will be derived for the considered districts and their surroundings as input for the applications in the joint project.

Using well-established statistical approaches from literature as well as derived by micro-scale model simulations (ENVI-met, SOLWEIG), the urban effect on climate data will be considered: first the mean Urban Heat Island (UHI) effect for the specific city is added to the climate data, second the UHI is modified by specific characteristics of the city districts (topography, current and future distribution of structure parameters like sky view factor, building height, street width, degree of surface sealing).

To evaluate the effect of a changing city planning (e.g., densification of dwelling zones, change of green areas) on bio-climate, the thermal exposure of residents is determined under extreme summer weather conditions using well-stablished indices (PET, UTCI) and the micro-scale models. The simulated data will be evaluated with measurements and are freely usable for non-commercial and public applications.

Our motivation for the project HRC lies in the improvement of networking and communicative interfaces with municipal decision makers as well as district managers and citizens' initiatives in order to apply scientific results on the heat stress in Dresden and Erfurt in practice.
