Effect of a linked park system on heat load


The urban development idea revolves around the creation and enhancement of a linked park system within the city to mitigate urban heat islands (UHI). This idea would involve the strategic design and expansion of green spaces, parks, and urban forests to counteract the negative impacts of increased temperatures and create a more comfortable and sustainable urban environment. The idea is to create not just a series of green spaces, but a cohesive system that benefits the environment, the climate, and the community.


Objectives of the use case are:

  • Assess Heat Load Reduction within Local Climate Zones:

The primary objective of UC2 is to quantify and analyse the impact of a linked park system, considering Local Climate Zones (LCZs), on reducing the heat load within the urban environment. This includes measuring changes in temperature, heat absorption, and heat distribution in areas where the park system is implemented and assessing how different LCZs influence the effectiveness of park-based cooling strategies. Additionally, exploring the correlation between park cooling indices and LCZ characteristics to provide practical insights for urban planning.

  • Evaluate Park System Efficiency:

UC2 aims to evaluate the efficiency of the linked park system in mitigating urban heat islands by examining its cooling effect during various seasons and under different weather conditions, considering the variations in LCZs across the city.

  • Determine Spatial and Temporal Variations in LCZ-Based Heat Load Reduction:

This use case seeks to identify spatial and temporal variations in heat load reduction within the city, considering factors such as park location, size, vegetation type, and proximity to residential and commercial areas, while also considering the LCZ classification of different areas.

Study area is the Greater Tunis which is a metropolitan region situated in northern Tunisia along the Mediterranean Sea coastline. It encompasses the capital city of Tunis and its surrounding urban areas.
