Abstract: Purpose: To evaluate the thermal performance of a green roof in a scale prototype under extreme heat conditions in a dry hot climate. Methodological design: The study is experimental and was developed in five phases: A state of the art review to choose prototype design criteria, design of the base prototype and green roof, construction of the prototypes, measurement of variables, and statistical analysis of the results. Results: The results demonstrated that the green roof significantly reduced the average daily indoor dry bulb temperature, 4.03°C on average, being within the thermal comfort zone 42.71 % of the measured time, in contrast to 18.75 % for base module. A decrease factor of 0.55 was obtained in the green roof and 1.30 in the base module, as well as a delay in reaching the maximum temperature on the interior surface of the slab of 4.86 hours for the green roof and 1.16 for the base module. Research Limitations: The results obtained describe the behavior of the prototype under the extreme heat of summer; in future studies, measurements should be taken throughout the four seasons. Findings: During the measured time, the green prototype maintained more stable and lower temperatures compared to the base module, demonstrating its effectiveness in reducing heat transfer and improving thermal comfort under extreme heat conditions in hot dry climates.
