Abstract
As part of the research work carried out by the main author as PhD. Thesis, indoor thermal environment of social housing in Ecuador has been evaluated, as well as possibilities to improve it in Portoviejo, based on roof solutions. In order to go deeper into the real thermal impact of traditional light roof solutions, a house in San Clemente beach has been taken, as study case to carry out measurements of indoor temperature during three days in February 2018.
Based on the probable expected behavior of indoor air temperature depending on volumetric and spatial typology, as well as building materials, context, and orientation, the effect of the roof exposition to solar radiation during sunny and cloudy days and spaces orientation is discussed.
Indoor temperature is always higher than outdoors, except on ground floor at noon, but on cloudy days, it may be up to 8 °C higher to outdoors, and up to 7 °C major than the one registered on the ground floor during the afternoon. Respect to orientation, achieved results confirm the importance of roof volumetric solution at this very low latitude.
