In the world and in Ecuador, housing continues to be one of the fundamental needs for human development and the enjoyment of a dignified life in accordance with the Ecuadorian constitution; It is also a human right according to the international standards of the United Nations (Gago Lorenzo, 2008). It is essential to build housing solutions that meet quality standards and technical parameters and can solve this housing need, but simultaneously the theoretical debate on the low-density city versus the high-density city is presented. In this discussion, most authors are in favor of a compact and densified city (Cabrera Jara et al., 2015) (Hermida et al., 2015); However, these studies do not consider the environmental and energy impact that occurs with construction, which is one of the activities that generates the greatest pollution worldwide. Recently, Latin American countries have introduced technological advances in construction systems and materials due to the reduction of construction costs; However, these new processes involve high levels of embodied energy. This research analyzes densified construction from the point of view of environmental and energy impact, considering the materials and construction systems used during the last decade. The analysis is carried out by comparing two case studies: a single-family housing building and a multi-family housing building, both cases located in the city of Cuenca-Ecuador. The Total Embodied Specific Energy (STEE) is quantified and the Total Specific Weight (STW) of the two case studies is addressed, the construction elements and materials have been classified into: Structure, Envelope and Finishes. The results of this research serve as an additional point of view of some of the environmental and energy aspects implicit in the construction of a compact and high-density city.
Análisis térmico comparativo de las cubiertas mayormente utilizadas en la ciudad de Cuenca, a partir de simulación digital térmica

The building envelope is the part of the structure that interacts with the environment. In buildings, approximately 33% of heat loss occurs through the walls. However, in countries with low latitudes, the roof is the critical structure because it is the main component exposed to solar radiation, which accounts for about 50 to 60% of the thermal energy exchange between the interior and exterior. In recent decades, Cuenca and Ecuador have undergone significant changes in their construction systems. The displacement of vernacular construction with new, more industrialized systems has resulted in greater productivity in construction time and costs, but has also led to the neglect of the climatic characteristics of the place. As a consequence, light tile roofs made of reed, mud, and stucco have been completely replaced by roofs with other technologies. The methodology used for this study is based on digital simulations utilizing the Design Builder software and the Energy Plus calculation engine. The analyzed case studies pertain to the most commonly used roof types in Cuenca construction. The study concluded that optimizing the radiative properties on the exterior surface of the roof, along with thermal mass and air cavity, is crucial. By applying these strategies, we were able to regularize the heat flow, resulting in low thermal oscillations and improved interior temperature conditions. This led to better performance for a heavy roof and, most importantly, significantly enhanced the performance of a light roof in our climatic environment.
EVALUACIÓN DEL IMPACTO DE LA TEMPERATURA EN VENTANAS Y CONFORT DEL USUARIO EN UNA VIVIENDA DE CUENCA - ECUADOR

The study focuses in the evaluation for thermal impact of windows temperature and incident on thermal comfort in a user home located in Cuenca, Ecuador. As a, objective is to analyze how the presence of certain variables affects temperature and thermal comfort inside the rooms. The methodology consists of continuous thermal measurements at three-hour intervals for six days, beginning at 6:00 PM and ending at 6:00 AM, using measuring instruments such as a thermal camera and a sound level meter. The data are analyzed for comparison in conjunction with a web application. This analysis determines effective textile barriers for increasing or decreasing temperature, controlling direct solar radiation, and regulating heat transfer through the window. The results not only provide a quantitative understanding of the thermal impact but also generate practical recommendations for improving the interior design and energy efficiency of homes in Cuenca with similar climate zones.
