Effects of Cool Roofs on Health and Indoor Environments
The Effects of Cool Roofs on Health, Environmental, and Economic Outcomes: a Global Multi-center Cluster-randomized Controlled Trial
This study is testing if special cool roofs that reflect sunlight can help people living in hot urban areas feel better and stay healthier by reducing heat exposure.

What this trial studies
This study investigates the impact of sunlight-reflecting cool roof coatings on indoor temperatures and health outcomes in urban climate hotspots across four regions: Ouagadougou, Burkina Faso; Ahmedabad, India; Niue; and Hermosillo, Mexico. By implementing a multi-centre cluster-randomized controlled trial, the research aims to assess how these cool roofs can reduce heat exposure and improve health conditions related to heat stress, such as cardiovascular and mental health issues. The study targets vulnerable populations living in poor housing conditions who are particularly affected by extreme heat. The ultimate goal is to identify effective passive housing adaptations that can enhance well-being and reduce health risks associated with climate change.
Who should consider this trial
Good fit: Ideal candidates for this study are permanent residents of households in urban areas experiencing high heat exposure and living in low-socioeconomic conditions.
Not a fit: Patients with roofs that are damaged or unstable, which would prevent the application of cool roof coatings, may not benefit from this study.
Why it matters
Potential benefit: If successful, this intervention could significantly improve health outcomes for individuals living in extreme heat conditions by reducing indoor temperatures and associated health risks.
How similar studies have performed: Other studies have shown promising results with similar passive cooling interventions, indicating potential for success in this novel approach.
