Urban Morphology Significantly Impacts Pedestrian Thermal Comfort

The physical arrangement and form of urban environments directly influence microclimates, which in turn significantly affect how comfortable people feel outdoors.

Journal of Daylighting · 2025

Key Findings

01Urban morphology is a key determinant of microclimate conditions.
02Microclimatic conditions directly influence pedestrian thermal comfort.
03There is a need for integrated approaches that link urban form, microclimate, and human comfort.

Application

Design takeaway

Incorporate detailed analysis of urban morphology's impact on microclimate and thermal comfort into the early stages of urban design projects.

How to apply

When designing public spaces or urban layouts, use simulation tools or established indices to predict microclimate conditions based on proposed morphological elements and assess potential thermal comfort levels for pedestrians.

Project actions

01When researching urban environments, look for studies that connect physical design features to environmental conditions and human experience.
02Consider using parametric tools to explore how changes in urban form might affect thermal comfort in your design project.

Method & Evidence

AimHow do specific urban morphological features influence microclimatic conditions and subsequently impact pedestrian thermal comfort?

MethodSystematic Literature Review and Parametric Analysis (General Morphological Analysis)

ProcedureA systematic review of existing literature was conducted using the PRISMA framework to identify trends and knowledge gaps. General Morphological Analysis was then applied to explore the influence of urban form variations on microclimate and thermal comfort, leading to the development of a framework that quantitatively links urban morphology, thermal indices, and pedestrian comfort.

ContextUrban Design, Environmental Planning, Human-Environment Interaction

Variables

IV["Urban morphological features (e.g., street width, building height, building density, orientation, aspect ratio)","Microclimatic conditions (e.g., air temperature, solar radiation, wind speed)"]

DV["Pedestrian thermal comfort (e.g., perceived temperature, physiological responses)"]

CV["Time of day","Season","Clothing insulation","Metabolic rate","Air quality"]

Strengths & Limitations

Strengths

+Systematic approach to literature review ensures comprehensive coverage of existing research.
+Parametric analysis provides a structured way to explore complex relationships between variables.

Limitations

It can be challenging to isolate the impact of urban morphology from other factors like weather patterns, human activity, and building energy use.

Reliability & validity

The systematic review methodology, if rigorously applied, enhances the reliability of the identified trends. The validity of the findings relies on the quality and scope of the reviewed literature and the robustness of the parametric analysis framework.

Think critically

To what extent can urban morphology alone mitigate the effects of a severe urban heat island, or are other interventions (e.g., green infrastructure, active cooling) always necessary?

Design Principles

"Design urban environments to optimize thermal comfort by carefully considering the interplay between form, microclimate, and human perception."

Understanding the relationship between urban design elements and thermal comfort is crucial for creating more livable and sustainable cities. Designers can leverage this knowledge to mitigate the negative effects of urban heat islands and enhance the well-being of city dwellers.

What This Means for Your Design

How a city is built affects how hot or cold it feels for people walking around, and designers can use this knowledge to make cities more comfortable.

How to use in your project

1.Reference this study to justify the importance of considering thermal comfort in your design project, especially if it involves urban or outdoor spaces.
2.Use the findings to inform your design decisions regarding building orientation, street width, material selection, and green space integration.
