Abstract

Urban overheating has become a critical environmental challenge in cities located in warm–humid climates, driven by rapid urbanization, increased surface impermeability, and the reduction of green areas. Among passive bioclimatic strategies, green roofs have gained attention for their potential to improve building thermal performance and mitigate the urban heat island effect. However, their effective implementation requires the integration of technical design criteria with local regulatory frameworks. This article analyzes bioclimatic design criteria and the regulatory context applicable to green roofs in the urban environment of Guayaquil. The study adopts a qualitative and descriptive approach based on a comprehensive review of scientific literature and an analysis of current building and urban regulations. Key bioclimatic parameters—such as substrate thickness, vegetation selection, water management, and structural considerations—are identified and contrasted with existing normative provisions to assess their compatibility and level of integration. The results reveal that, while green roofs demonstrate significant potential to reduce surface temperatures and enhance thermal comfort in warm–humid conditions, local regulations lack specific technical guidelines to support their standardized application. This regulatory gap limits the widespread adoption of green roofs as a climate-responsive urban strategy. The findings highlight the need to incorporate explicit bioclimatic and technical criteria for green roof design into local regulatory instruments. Establishing such guidelines could facilitate their implementation, improve thermal performance in buildings, and contribute to broader urban sustainability and climate adaptation goals.
