Kurze Zusammenfassung

Annex 97 / Task 5 Sustainable Cooling in Cities provides an interdisciplinary framework for developing and implementing sustainable cooling strategies in urban environments. By integrating technological innovations, urban design adaptations, and policy measures, it aims to create climate-resilient and liveable cities for the future.

Ziele

Sustainable Cooling in Cities (full title: IEA EBC Annex 97 / Task 5 Sustainable Cooling in Cities) aims to advance knowledge on effective heat mitigation and sustainable cooling strategies in cities placing a strong emphasis on the interaction between outdoor heat mitigation and building cooling.

The project has four key objectives:

  1. Fundamentals: Establish environmental criteria and key performance indicators (KPIs) for sustainable cooling.

  2. Methods: Develop simulation and experimental methods for assessing cooling technologies.

  3. Solutions: Identify and evaluate urban cooling and building-specific solutions.

  4. Policy: Promote best practices and evidence-based policymaking.

Methodik

The project examines cooling strategies at three scales:

  1. Large Scale (city-wide): e.g., Urban morphology adjustments, wind corridors, and green/blue infrastructures

  2. Medium Scale (neighbourhoods): e.g., shading, vegetation, and cooling materials

  3. Small Scale (immediate surrounding of a building): e.g., efficient cooling technologies such as district cooling, solar cooling, and natural ventilation

The cooling solutions explored include:

  • Nature-based solutions (e.g., vegetation, water features, evaporative cooling)

  • Grey solutions (e.g., reflective materials, structural shading)

  • Mechanical solutions (e.g., district cooling, adsorption chillers, seawater cooling)

  • Soft Solutions (behavioural and operational strategies) (e.g., adaptive usage patterns, public awareness raising)

Ergebnisse

Zu den wichtigsten Ergebnissen gehören:

  • Bericht über den Stand der Technik zu städtischen Kühlstrategien

  • Entwicklung von Schlüsselleistungsindikatoren (KPI)

  • Richtlinien für Experimente und Simulationen

  • Technologieprofile

  • Politikempfehlungen
