Key Findings

01Urban compactness can reduce emissions in smaller cities but may increase them in megacities.
02Three-dimensional morphological indicators (e.g., building height) show a U-shaped effect on operational carbon emissions, influenced by microclimate.
03Most studies focus on operational carbon, with limited life-cycle assessments and embodied carbon analysis.

Application

Design takeaway

Adopt a context-aware approach to urban renewal, recognizing that design decisions about urban form have varied and often non-linear effects on carbon emissions.

How to apply

When designing urban renewal projects, analyze the specific urban morphology and scale to predict its impact on carbon emissions, and consider incorporating three-dimensional elements strategically.

Project actions

01When researching urban renewal, look for studies that consider the specific context of the city.
02Consider the full life cycle of materials and energy use, not just the operational phase.

Method & Evidence

AimHow does urban morphology influence carbon emissions during urban renewal, and what are the key mediating factors and variations across different urban contexts?

MethodSystematic Literature Review

ProcedureA comprehensive review of over 100 empirical studies from the Web of Science was conducted to synthesize findings on the impact of urban form on carbon emissions within the context of urban renewal.

DV["Carbon emissions (operational, embodied, life-cycle)"]

CV["Climate zone","Urban function","Urban renewal stage"]

Strengths & Limitations

Strengths

+Systematic approach ensures comprehensive coverage of relevant literature.
+Focus on urban renewal provides a specific and relevant context.

Limitations

The findings are based on a review of existing literature, which may have its own limitations in terms of data availability and methodological approaches.

Reliability & validity

The reliability of the findings is supported by the systematic review methodology. Validity is enhanced by synthesizing a large number of empirical studies, though it is limited by the quality and scope of the original research.

Think critically

Given the U-shaped effect of building height, what are the optimal design strategies for maximizing daylight and minimizing energy use while also considering aesthetic and social factors?

Design Principles

"Contextualize urban form interventions based on city scale, climate, and life-cycle carbon impacts."

Understanding these nuanced relationships is critical for designers and urban planners aiming to implement effective low-carbon strategies. Ignoring spatial heterogeneity and non-linear effects can lead to inefficient or counterproductive renewal projects.

What This Means for Your Design

How we build and shape our cities affects how much carbon they produce, and it's not always a simple relationship. What works for a small town might not work for a huge city, and things like building height can have surprising effects.

Paragraph starter

This research highlights that the impact of urban morphology on carbon emissions during urban renewal is complex and non-linear, varying with city size and specific features. Designers must therefore adopt context-specific strategies, considering factors like urban compactness and building height, and ideally incorporating life-cycle assessments to ensure truly sustainable outcomes.
