EVALUACIÓN DEL IMPACTO DE LA TEMPERATURA EN VENTANAS Y CONFORT DEL USUARIO EN UNA VIVIENDA DE CUENCA - ECUADOR
(Universidad de Cuenca. Facultad de Arquitectura, 2025-11-20) Campoverde Cobos, Daniela Carolina; Torres Quezada, Jefferson Eloy
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.
Aportes teórico-prácticos de la conversión de uso de tierras agrícolas desde la perspectiva de la expansión urbana en América Latina, 2018 a 2023: Revisión sistemática de literatura
(Universidad de Cuenca. Facultad de Arquitectura, 2025-11-06) Rojas Jiménez, Stephanye Karolina; Rodas Beltrán, Ana Patricia
This research addresses the issue of agricultural land conversion as a consequence of urban expansion in Latin America, a complex phenomenon influenced by economic, political, social, and environmental factors that particularly affects high-value productive lands essential for the population's food security. Through a systematic literature review (SLR), 15 scientific articles published between 2018 and 2023, indexed in SCOPUS, Dialnet, and SciELO databases, were analyzed. The qualitative analysis, conducted using ATLAS.ti25 software, enabled the coding and establishment of relationships between main variables, generating analytical tables and semantic networks that demonstrate the persistent trend of urban expansion at the expense of agricultural lands in the region. The findings emphasize the urgent need to implement public territorial planning policies that allow for more effective and sustainable management of these territorial transformation processes, considering both urban development demands and the preservation of strategic agricultural areas for the region.
Contradicciones en la planeación urbana participativa: el caso del Plan de Mejoramiento de Barrios Periféricos de Cuenca. Caso San José de Balzay
(Universidad de Cuenca. Facultad de Arquitectura y Urbanismo, 2025-10-20) Martínez Roldán, Paúl Sebastián; Rogel Salazar, Rosario
Participatory urban planning was enshrined in Ecuador through the 2008 Constitution and the 2010 Organic Law on Citizen Participation, yet its practice often exposes tensions that erode policy effectiveness. This study investigates contradictions that emerge when social participation is integrated into the implementation of Cuenca’s Peripheral Neighborhood Improvement Plan, using San José de Balzay as a case study. An exploratory, comparative qualitative design was applied, involving two focus groups (six municipal technicians and six neighborhood leaders; April 2024). Transcripts were processed with Voyant Tools to detect lexical patterns and systematically contrast institutional and community views. Findings reveal mismatches between formal participatory mechanisms and local practices, along with institutional barriers that constrain citizen influence across planning and implementation processes for policy.
Influencia de la Participación Ciudadana en la Recuperación de Espacios Públicos: Estudio en el Barrio Sevilla de Oro en la Ciudad de Loja, Ecuador
(Universidad de Cuenca. Facultad de Arquitectura, 2025-10-21) Cuenca Vargas, Fabián Andrés; Salazar Vintimilla, Ana Cecilia
The management of public space requires citizen participation to involve its inhabitants in improvements for a better quality of life, hence the importance of knowing the perception of satisfaction of those involved. The general objective was to evaluate, from the perception of satisfaction of the community, the strategies of citizen participation implemented in the public space called: "Colors of our history" in the Sevilla de Oro Neighborhood in Loja, Ecuador, carried out between 2018 and 2023. A field methodology was used, descriptive, with mixed approach, using a survey questionnaire and focus groups. The survey revealed that of the 124 respondents, 90% are satisfied with the implementation of the project, 98% felt included in decision making, 96% consider that the project reflects the needs and preferences of the community, 92% believe that citizen participation was effective in improving public space, 90% are satisfied with the design of the EERSSA stairways, 88% consider that they represent a safe and welcoming public space, for individual and collective enjoyment, 96% believe that they contribute to a better quality of life, 90% revealed to be satisfied with the management of the urban planning project. Based on the focus groups, they value citizen participation strategies for the transformation of public space. They highlighted cooperation, involvement, commitment, a sense of belonging, and empowerment. It is concluded that, based on residents' perceptions of satisfaction, citizen participation strategies were positive in transforming urban spaces, as they promote social interactions, mutual understanding, and safe and peaceful coexistence.
Análisis comparativo de la energía incorporada total específica. Caso de estudio: edificación residencial unifamiliar y multifamiliar Cuenca – Ecuador
(Universidad de Cuenca, 2025-07-24) López Mogrovejo, Paúl Mateo; Torres Quezada, Jefferson Eloy
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.
Respuesta al lugar en la obra de Francisco Artigas en EL Pedregal 1950 – 1962
(Universidad de Cuenca, 2025-07-21) Quituisaca Leon, Byron Fernando; Sinchi Toral, Iván Paúl
This research shows the fundamental decisions of the work of Francisco Artigas within El Pedregal, the most important urbanization of modern Latin American architecture in Mexico, analyzed from the consideration of place understood as a problem of form. Additionally, the work in El Pedregal will be approached as a single project, where each house is part of a larger global system that is formed and organized according to an architectural criterion based on the arrangement of elements in space. The characteristics of the collected information, consisting of articles, plans, and period photographs, focus on visions of the project condensed for publications, which forces the analysis to adjust to an alternative view of the conception process. Thus, each house is visualized as a sketch or plan within this global conception process, which includes a total of 16 houses distinguished by their architectural quality. This reveals constant aspects such as the placement on the most characteristic site, visual relationships, the horizontal, the access route, the jagged façade, and the perception of the building. Likewise, emphasis is placed on a graphic analysis, as by observing the photographs of the houses, three points of view that prevail in the different projects are revealed. In fact, Artigas proposes two fundamental criteria in response to the Pedregal environment: one horizontal that allows locating oneself on the rock, and verticals that allow inhabiting it.
El proyecto como reconstrucción, en la obra doméstica de Arne Jacobsen, vivienda casa Kokfelt 1955-57, casa Erik Siesby 1957
(Universidad de Cuenca, 2025-06-14) Carrillo Jara, Jamil Israel; Proaño Escandón, Diego Javier
The analysis of Arne Jacobsen’s works reveals a recurring structural pattern based on central supports and cantilevers. Three key stages can be identified in his architecture: the use of the cantilever system, the liberation of façades through continuous carpentry, and a mature phase characterized by complex architectural proposals. This research focuses on establishing a connection between two of his most representative domestic works: the Kokfelt House (1955–1957) and the Siesby House (1957), despite the limited documentation available on his residential projects compared to his public buildings. The aim is to highlight the principles of modern architecture applied by Jacobsen in the domestic sphere, through the use of graphic and documentary resources that contribute to understanding and appreciating his contribution to the history of modern architecture.
La forma del edificio como respuesta al lugar dos casos de estudio de arquitectura moderna: edificio ex Banco Popular actual, EERSA por Ramiro Pérez, Riobamba1968 edificio ex Consejo Provincial de Chimborazo por Oswaldo Muñoz Mariño, Riobamba 1972
(Universidad de Cuenca, 2025-02-11) Calle Lema, Luis Ranulfo; León González, Pablo Armando
Modern architecture does not interpret preexistences as a norm or rule to be submitted to, but rather determines the relationships of the elements that make it up; therefore, it coexists with climatic, geographic, topographic, and sociocultural factors, aspects that contribute to the conception of the object's form. However, the research focuses on studying the relationships of the criteria of modern architecture with the elements of the place, through adequate recognition of the same, they generate objects with identity and originality; an unavoidable process when designing architecture. To address the research on the design strategies of the building and the pla-ce, it is necessary to interpret Cristina Gastón methodology (Mies the pro-ject as a revelation of the place and the modern project research guidelines). methodology that will allow us to know the conception process of the former Banco Popular building, now EERSA, by Ramiro Pérez in 1968 and the for-mer Provincial Council of Chimborazo by Oswaldo Muños Mariño in 1972. Finally, the research focuses on the digital reconstruction of the buildings and the place; Using photographic resources from the period, original plans, and a photogrammetric survey of the site using a drone, this information will allow us to approach the reality and conception of the buildings; through aesthetic judgment, the strategies and criteria of modern architecture used in the design of the buil-dings are determined.
Caracterización físico - mecánica de la madera aserrada Eucalipto (Eucalyptus globulus) comercializada en el cantón Cuenca
(Universidad de Cuenca, 2025-02-06) Rojas Sigüenza, Esteban Paúl; Quezada Molina, Juan Felipe
The construction sector is continuously searching for more sustainable and efficient processes. In this context, the present thesis aims to determine the structural physical-mechanical properties of eucalyptus lumber marketed in Cuenca, Ecuador, according to the Ecuadorian Construction Standard (NEC), in order to improve its knowledge and use in the industry. An applied and experimental laboratory research was employed, using a quantitative methodology. Tests performed on Eucalyptus globulus wood revealed significant differences between the average values obtained and the JUNAC standards for properties such as static bending and compression parallel to the grain. Although the physical-mechanical properties of the wood do not completely conform to the standards, the results allow the identification of important variations in their behavior. This information is fundamental for the selection and design of construction projects, especially in social housing. The findings are key to establish the admissible efforts in structural pre-dimensioning and to promote the use of sustainable materials in the construction of safe and durable infrastructures. In addition, they highlight the potential of eucalyptus wood as a viable alternative in sustainable construction, contributing to the development of safe and efficient housing.
Tendencias teórico-prácticas en estudios críticos de rehabilitación urbana desde la perspectiva de género: intervenciones en centros históricos en Ecuador y Perú (1980-2024)
(Universidad de Cuenca, 2025-01-08) Andrade Bracero, Karen Antonella; Salazar Vintimilla, Ana Cecilia
Accelerated urbanization in Latin America has initiated a reflective process: re-urbanization. This transformation focuses on historic city cores, which face challenges to achieve gender equality. To understand the progress of urban interventions in historic centers from a comprehensive planning, the evolution of the theoretical-practical trends present in 12 studies was analyzed, after the review of 31,091 titles, on the urban intervention of historic centers of Ecuador and Peru for 44 years, using a gender perspective. The texts were selected and excluded based on the language, year of publication, type of support, use of universal identifiers (ISBN, ISSN, and DOI), and the syntax of their titles; and reviewed in MAXQDA2024. Thus, changes were identified in the consideration of the gender dimension in these studies, based on the systematic review of qualitative literature as a technique, focused on the search for theoretical articles and books through Web Of Science, Dialnet, Everand, and ProQuest Ebook Central. Among the most relevant results, despite not generating conclusive results between 1980 and 2000, a transition was found between the end of the 20th century and the 21st century, which went from a focus on heritage conservation to one of renewal and, finally, comprehensive urban rehabilitation. It was determined that the gender approach was incorporated in texts published in the last two to three years, particularly in studies on Ecuadorian historical centers.
Enfoque de la participación ciudadana en la aprobación del Plan Urbanístico Complementario: estudio de caso de Racar, Cuenca, Ecuador
(Universidad de Cuenca, 2024-11-19) Sarmiento Narváez, Remigio Desiderio; Salazar Vintimilla, Ana Cecilia
Citizen participation in urban plans in Ecuador is crucial to promote economic development and local, regional and national social well-being. This study aims to improve the understanding of citizen participation in the GAD-Municipality of Cuenca. This research analyzes the approval process of complementary urban action plans in the Racar region, Cuenca, Ecuador. This is a qualitative and descriptive study. It examines the forms of intervention and interaction of both municipal officials and community. The results indicate that a single approach of citizen participation was not applied in the approval of the Racar Urban Action Plan; Instead, three approaches were found: informational approach, pluralistic approach, and consultative approach, but the informational approach predominated. Various methods were used to promote citizen participation, including workshops and community meetings. However, differences in criteria and lack of conceptual precision concerning the mechanisms of citizen participation were also found. Findings permit conclude that the quality of citizen participation is low since it is reduced to an informative practice, which generates discontent and frustration among citizens. On the other hand, a series of technical, procedural, communication, and administrative barriers that affected citizen participation were identified.
Criterios y valores de la modernidad en la obra de Enrique Seoane Ros. Edificio del Ex Ministerio de Educación del Perú. Lima, Perú. 1951 - 1959
(Universidad de Cuenca, 2024-11-14) De la Piedra Medina, José Miguel; Guerra Galán, Jaime Augusto
The arrival of the modern era in Peru occurred under a scenario that, in its beginning, developed a neocolonial architecture wanting to preserve local features very typical of Peruvian culture, this produced a late arrival of the modern movement, having a main support current called “rationalist”, between the 1940s. During the following decades, the character of Enrique Seoane Ros (ESR) became one of the main exponents of modern architecture in Peru. Among his creations is the former Ministry of Education building, which was designated as the country’s cultural heritage in 2020. The objective of this research is to value the production of the architect ESR, to recognize the formal, architectural values of modernity and urban aspects of his work in the period from 1951 to 1959, since here his modernist rise emancipates the forms, income, hierarchy and other functional strategies of his work. A graphic analysis is carried out, with the methodology proposed by Cristina Gastón and Teresa Rovira in “The Modern Project Research Guidelines” (2007), where the authors recognize that the transcendental characteristics of a building such as its architecture, spatiality, interior design and Constructive definitions are the set of aspects and considerations to be studied in a thorough analysis of the project. The research is expected to determine and identify the criteria and values of modernity, as well as understand the aspects and urban solutions in the work of ESR and the validity of modern Architecture in the city of Lima - Peru.
Análisis comparativo del confort térmico entre unidades de vivienda con diferentes sistemas constructivos ubicadas sobre 3000 m.s.n.m.
(Universidad de Cuenca, 2024-11-12) Moreno Albuja, Andrea Nataly; Guillén Mena, Vanessa Fernanda
Thermal comfort in housing ensures a better quality of life for its occupants. In recent years, the consummation of contemporary houses with vernacular influence has been observed. These houses typically located in rural areas, have the potential to regulate the thermal environment with fewer energy resources, while contemporary homes often generate a prolonged exposure to low temperatures, which is reflected in the health of their inhabitants. This research compares the thermal comfort between two contemporary houses with vernacular influence (TRA-01 and TRA-02) and two houses with regular contemporary construction systems (CON-01 and CON-02) located in the rural parish of San Juan, Riobamba canton, situated at approximately 3,200 meters above sea level. To carry out this comparison, the variables of exterior and interior temperature and relative humidity were monitored over a period of 8 days, with readings taken every 5 minutes for subsequent processing. Additionally, to establish the thermal comfort range of each house, the predominant outdoor average temperature was used and to evaluate the thermal comfort, the operative temperature was obtained, which is one of the most used indexes for assessing thermal comfort. Furthermore, to complement the study, thermal perception surveys were conducted among the users of the houses. The results show that contemporary houses with vernacular influence exhibited a stable interior temperature with an average fluctuation of (2.13°C); however, only one of the houses (TRA-02) was within the comfort range 37.5% of the time while (TRA-01) being 100% of the time outside the comfort range. In the regular contemporary houses, much wider ranges of internal oscillation were observed (7.57°C), resulting in both houses (CON-01 and CON-02) being outside of the comfort range 85,06% and 100% of the time severally. The difference in thermal behavior between vernacular and contemporary homes is due to the value of the thermal envelope transmittance, The main passive strategies used in the dwellings with the best thermal performance were (TRA-01) the orientation regarding the predominant wind, the thermal mass and the attached greenhouse, (TRA-02) the search for the optimal orientation, the optimization of the openings and the correct selection of the type of glass and carpentry and (CON -02) the thermal mass on the roof and the existing enclosure layer which demonstrates that the thermal response is not solely a function of the construction system used, but rather, a system of complex variables such as thermal transmittance (U value), the immediate environment, the amount of glass surface, the orientation of the home and especially the quality of the construction.
Análisis comparativo entre simulador ambiental en BIM Ecodesigner y DesignBuilder, comparando resultados obtenidos entre ellos, en parámetros de temperatura interior detectados y estos frente a la realidad
(Universidad de Cuenca, 2024-11-11) Sánchez Salazar, Giselle Betzabe; Zalamea León, Esteban Felipe
The importance of reducing energy consumption in buildings has led to the use of software that can predict the thermal performance of a building by entering the location and construction data, nevertheless, this type of software has shown a discrepancy in the results compared to in situ measured thermal data, and this issue has not been sufficiently studied in climates close to the equator line, to investigate this difference and the configuration that can produce the most precise results, three classrooms buildings from the faculty of architecture of the university of Cuenca that are modeled in Design Builder and ArchiCAD are taken to simulate thermal comfort parameters, the same configuration is introduced in both software and the simulation of temperature and humidity were compared with the measured data. Analyzing the results allows us to determine the precision of the two software been placed in the same circumstances at the climate zone of Cuenca, Ecuador, for that, interior measurements are taken with temperature, humidity and 𝐶𝑂ଶ sensors, as well as exterior measurements using a weather station. The simulations´ results provided a comparison table where the average result can be used as a correction factor, for Design Builder’s case a ±0.81°C and 5% of mean absolute difference (MAE) was obtained for the temperature and humidity simulated and a ±0.91°C and 6.09% of difference for the temperature and humidity simulated in Ecodesigner STAR plug-in from ArchiCAD, this data is obtained after calibration which placed the ventilation for the brick buildings (E1 and E2) in 20ACH, 30ACH and 40ACH, and the insulated concrete block building (E3) a ventilation of 15 ACH within their respective occupancy and ventilation schedule. This research helps identify the parameters and variables that affect the thermal simulation results providing an analysis of the simulation software use, workflow and the results with a comparative vision, finally, the values obtained as a mean absolute error can be used as a correction.
Análisis urbano-arquitectónico basado en criterios modernos de la ciudadela La Granja, Quito-Ecuador
(Universidad de Cuenca, 2024-11-12) Heras Olalla, Jessica Mabel; Vanegas Peña, Agustín Santiago
Faced with the accelerated expansion of cities towards the periphery and the incessant proliferation of urbanizations that fragment the city, this research analyzes the citadel La Granja (1975) as a project that integrates the cell of inhabiting into the urban grid, and that brings together modern attributes that provide quality to the project that, after 50 years of its construction, It is a benchmark of quality with respect to the role of housing in the construction of the city. The research has an exploratory scope and a mixed methodology, where literature review, redrawing, comparative analysis and interviews were the main methodological tools. The study encompasses the theoretical approach to modernity, principles of modern urbanism and attributes of the modern form; as well as the political, social and economic background of the case study and the city of Quito. The comparative analysis at the urban level is carried out between the original project and the built one. On an architectural level, 5 types of housing that were built respecting the original planning are analyzed. At the urban level, the main findings show that, in the original project of La Granja, the same urban principles of the Regulatory Plan of Quito (1942) are found and, although it was not fully materialized due to external factors (political and economic), these principles remain in force. On the other hand, the analysis of the living cells shows that the attributes of the modern form, present in the buildings, endow the complex with identity and functional, visual and constructive consistency, obtaining as a result a project of exceptional value that has transcended time.
Uso de los tejidos del tallo de la totora (Schoenoplectus californicus) en la creación de prototipos de tableros aislantes térmicos
(Universidad de Cuenca, 2024-11-05) Auquilla Clavijo, Sebastián Felipe; Hidalgo Cordero, Juan Fernando
The construction sector consumes a large amount of energy and resources. To mitigate these impacts, numerous research efforts seek solutions with consideration of local conditions. In this regard, the present research focuses on generating materials applicable to sustainable construction in the South American setting, using Totora (Schoenoplectus californicus sp.) as raw material for the production of alternative thermal insulation materials. From harvesting to shredding and prototype development, its properties are evaluated, including compression, environmental moisture absorption, density, and thermal conductivity. The results show that Totora is a promising option for thermal insulation, highlighting its renewable and local origin, promoting sustainability, and strengthening the regional economy. This approach aims to reduce CO2 emissions, minimize waste and responsibly utilize local resources while emphasizing the importance of alternative materials for environmental and economic sustainability in construction.
Resistencia mecánica de losa estructural prefabricada de madera para entrepisos
(Universidad de Cuenca, 2024-11-08) Ordóñez Gutiérrez, Juan Carlos; Aguirre Collahuazo, Jonnathan Patricio
The central objective of this work is to design a prefabricated wooden slab, supported by the analysis of research on prefabricated wood, which has provided significant theoretical advances in recent years. This work develops a prefabricated wooden slab to validate its structural suitability through load tests, such as shear and bending forces. The results of these tests support its implementation in housing construction and contribute to more sustainable construction practices. Through the load test, it is possible to determine the mechanical properties of the wooden prototype for mezzanines, with the aim of evaluating its structural safety capacity in homes. It should be noted that the data obtained from this trial provides crucial information that supports the feasibility and effectiveness of using this slab in the construction of residential buildings. These results were used to verify compliance with the minimum resistance levels established in NCh1198, 2014, for wooden roofs and mezzanines. Taking into account that this type of wooden structure has demonstrated constructive and environmental advantages compared to concrete and steel construction methods, it offers more sustainable and efficient alternatives.
Lacaton & Vassal: la rehabilitación de edificios bajo los principios de la modernidad, dos casos de estudio
(Universidad de Cuenca, 2024-07-10) Aucapiña Maldonado, Daniel Agustin; Sánchez Castillo, José Hernán
According to Kevin Lynch (1964), the city is a set of various elements that are in continuous change to meet the needs of the inhabitants, therefore, the buildings that are part of the urban landscape undergo constant transformations. Thus, the need arises to provide optimal solutions for buildings that have become obsolete due to the different factors that the passage of time entails or simply require adaptation to new uses. The main objective of this research is to identify and highlight the principles of modern architecture in the work of Lacaton and Vassal, winners of the Pritzker Prize, a ceremony in which their sustainable carácter was highlighted in transformation projects, for which a qualitative methodology will be applied taking as a reference the five principles of modern architecture proposed by Helio Piñón (1998) in his book "The meaning of modern architecture" in the analysis of two of the most representative works in the field of rehabilitation as case studies: Transformation of 530 housing units in Bordeaux and the Transformation and densification of a housing tower in La Chesnaie in Saint Nazaire.
Edificios modernos educativos análisis comparativo Facultad de Ingeniería, Universidad Politécnica Nacional – Quito aulario I (bloque b), Universidad de Cuenca – campus Balzay – Cuenca
(Universidad de Cuenca, 2024-06-26) Ulloa Dumas, Juan Fernando; Guerra Galán, Jaime Augusto
The interest in understanding and comprehending how academic modern architecture was and is carried out was the primary motivation for undertaking this work. This thesis project focuses on modern architecture developed in two different periods in Ecuador: one originating from the 1960s in the city of Quito, and the second corresponding to a recent period, in 2021, in the city of Cuenca. Within this field of modern architecture, there have been investigations conducted by the Faculty of Architecture and Urbanism of Cuenca. Thanks to these, we have gained knowledge of a part of history where values of universality, and criteria of form and function, prevailed. Consequently, this research work performs a comparative analysis of the principles of modern architecture in two academic buildings from two different eras in Ecuador, and how these principles have varied over time—one designed by architect Mario Arias Salazar, and the other by the Duran & Hermida studio. An analytical-deductive approach is employed, focusing on the reconfiguration of case studies, where the standards used by the author in each work are detected. This will be validated through the examination of emblematic examples of universal scope, which will serve to establish the shared and/or distinctive traits or criteria that facilitate the evaluation, confirmation, confrontation, and debate of the particularities presented by both works. The aim of the work is to determine the modern formal and constructive values and decisions that have changed over time within the studied works, examining and validating characteristics or postulates of architectural quality.
Análisis térmico comparativo de las cubiertas mayormente utilizadas en la ciudad de Cuenca, a partir de simulación digital térmica
(Universidad de Cuenca, 2024-02-21) Villa Enderica, Jonnathan Daniel; Torres Quezada, Jefferson Eloy
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.
