BLUE-GREEN INFRASTRUCTURE IN BAGHDAD’S RESIDENTIAL COMPLEXES

Abstract

Motivates: Studies have shown that many cities worldwide face environmental challenges imposed by climate change and rapid urban expansion, which reduces green spaces and transforms them into urban areas. Addressing these challenges requires the adoption of methodologies and strategies and methodologies that promote blue-green infrastructure, which integrate greening and water features to enhance thermal comfort, public health, and overall quality of life. Aims: This study provides a context-specific evaluation of Blue-Green Infrastructure in the hot-arid climate of Baghdad, where extreme heat and low humidity create microclimatic conditions distinct from those of temperate regions commonly addressed in previous research. The research examines key microclimate indicators – Potential Air Temperature, Sky View Factor (SVF), Mean Radiant Temperature (MRT), Relative Humidity, and PMV – within a residential complex to assess the effectiveness of BGI in improving outdoor thermal comfort. The study addresses a knowledge gap regarding the role of BGI in mitigating heat stress in Baghdad and demonstrates that integrating vegetation and water elements can contribute to reducing temperatures and enhancing comfort levels in hot-dry environments. Results: The research findings confirm the significant impact of blue-green infrastructure in improving the climatic conditions of residential complexes in Baghdad.
