Abstract Introduction. This article presents the final results of the research Analysis of the thermal comfort of residential complexes carried out in the city of Portoviejo, Ecuador. Objective. Analyze the perception of thermal comfort of the housing units of the Fuentes del Río housing complex in the city of Portoviejo and recognize the elements that favor or not the climatic quality of the interior of their spaces, through research techniques and technological tools, demonstrating the value of orienting the buildings of a residential nature according to the climatic conditions that influence them. Materials and methods. A bibliographic and field research is presented, supported by the diagnosis of the architectural complex under study. Results. Once the valuations were obtained, we proceeded by means of design strategies to devise elements that mitigate the climatic incidences inside homes, in addition to preparing a list of bioclimatic parameters that contribute to the projection of future urban complexes in the urban area of the city of Portoviejo. Conclusions. The elements analyzed allow us to recognize the importance of using bioclimatic parameters or principles of sustainable architecture and the use of constructive technology that empower the creation of sustainable housing programs, contributing positively to the environment and improving the habitability of the spaces.

RESUMO
This dataset is part of the article entitled "Design and experimental study of a low-cost prefab Trombe Wall to improve indoor temperatures in social housing in the Biobío Region in Chile" [1], [2]. The dataset represents the outcome of experimental measurements during a 1-year monitoring campaign to assess the performance of an adaptable and low-cost prefabricated Trombe Wall (TW) with a vertical water storage system. The experiments include periods with mobile insulation during winter nights and external shading during summer which were added to test their effect on the thermal performance. Temperature sensors were used to measure and compare the temperature in two test cells: one with and one without the TW. Following the National Chilean Standard [3], the experiment was done in the interior valley (Chillan), a Mediterranean climate (Csb), according to the Köppen climate classification [4]. The two test cells were designed to represent the most used area of a social housing unit in combination with the most widely used type of window in north façades in the region. One test cell was built exactly as the social housing unit, while the second test cell included a low-cost Trombe wall. Five temperature sensors were installed in the test cells. The thermal performance of the TW was monitored and analysed for the first time in Chile, providing insights in the thermal performance of the TW and proving the potential effectiveness of seasonal variations to improve winter and summer performances.
RESUMO
Buildings constructed according to bioclimatic architectural principles in amenable climates have often experienced posterior interventions that have closed ventilation openings for the installation of air conditioning units. The present work sought to investigate the reasons for installing air conditioning equipment in buildings even under adverse economic conditions and with the awareness of their negative environmental implications. The Faculty of Architecture building at the Federal University of Bahia, located in the city of Salvador, Bahia State, Brazil, was the focus of the present investigation. It was determined that the lack of maintenance of the windows and window frames, and the closing of projected openings compromised natural ventilation. The study confirmed the adequacy of the architectural project in relation to the local climate, and in loco measurements likewise confirmed the efficiency of natural ventilation through the windows and other openings in the faculty room and classrooms examined. The results of the interviews concerning thermal comfort indicated that 53% of the users felt comfortable. Nonetheless, it was found that the building's windows and window frames were poorly maintained, compromising their ability to facilitate efficient natural ventilation and significantly diminishing the capacity for thermal regulation in the building. This study calls attention to the necessity of refining and improving the maintenance of university buildings to reduce the intensive use of artificial air conditioning in detriment to investments in projects that could lend priority to natural ventilation and the maintenance of good window operating conditions.
