Roof-integrated phase change materials for urban heat island mitigation: advances and strategies

Key Points

• Phase change materials significantly enhance thermal performance of roofs, reducing urban heat island effects.
• Increased energy efficiency by 15% is observed in urban areas using integrated phase change materials.
• Assessment using various strategies on roof designs reveals innovative approaches for urban heat island mitigation.
• This work highlights a critical need for broader implementation and testing of phase change materials in urban environments.
