Re)Programa. Architectural Rehabilitation Incorporating Sustainability Criteria in an Andalusia Neighborhood

Between the years 2013–2015, members of the research group TEP 954 InFact, worked on a I + D contract awarded by the Department of Public Works of the Government of Andalusia, studying the needs for intervention in the Andalusian buildings from the 40s with the aim of ensuring “active ageing” and “at home”. The research proposes a new urban model which ensures that people can stay in their neighborhoods until the end of their days, from projects focused on standards comfort requirements, energy saving and environmental sustainability to management under socioeconomic criteria. A diagnosis of the building state of conservation and a testing of the degree of fulfillment the architectural requirements were performed according to Law 8/2013 guidelines. Regarding the urban livability, the weaknesses identified in the Building Evaluation Report (IEE) and the need to prioritize adjusted performances to socioeconomic characteristics of neighborhoods, promoted a critical review and the development of new diagnosis tools. These tools will allow make decisions that ensure the accessibility and the use of friendly spaces with elderly promoting active ageing. Among the conclusions, the clear deficiencies in the thermal behavior of the envelope, but above all accessibility of buildings, have highlighted the need for urgent intervention. In this article the results obtained in relation to the supervision of the basic safety requirements of use and accessibility, from new Inspection Sheets considered as a tool for development and improvement is exposed.

The Empathic City. Towards a New Model of Urban Sociability

The city is a physical and social construction made by man, which affects the daily life of citizens and therefore has become the main focus of social and human relations, able to respond to their needs and ensure a better life quality. That is why it is necessary to analyze and study the habitability and quality of life in urban contexts as a paradigm and reference for the development of social and collective life through the public space and the urban fabric. The research seeks to create a methodology for the qualitative analysis of the public space through the research-action that will develop the DEU tool (Diagnosis of Urban Empathy Urban).

Structural Refurbishment Projects. The Sustainability of Reinforcements Using Composite Materials

Repair works of reinforced concrete structures are complex, expensive, and with a strong impact on the environment . Repair solutions with composite materials , FRP (Fibre Reinforced Polymer), are the most efficient, if we consider mechanical characteristics and lightness. To assess its sustainability it is necessary to analyze this type of structural rehabilitation operations from environmental and economic criteria, but mainly social, considering people living in buildings and using infrastructure, as well as workers. Through a documentary work in three Andalusian companies: Vorsevi, Labrum and Azul Construccion, about different investigations, studies and works of carbon fiber reinforcements CFRP (Carbon Fibre Reinforced Polymer), an analysis of the circumstances and the complexity of works, environmental impacts and over citizen, and issues related to quality control to ensure proper operation, durability, and long-term impacts amortization, was developed. It is included a comparative analysis between CFRP reinforcements and other most commonly reinforcements used in construction .

Informes de reflexión en la docencia de Estructuras mediante aprendizaje basado en problemas

Realizamos una sintesis sobre el estado del conocimiento respecto a la reflexion en el aprendizaje: significado, utilidad y estrategias. A continuacion presentamos un estudio de caso en la asignatura Estructuras 1 en el grado de Fundamentos de Arquitectura de la Universidad de Sevilla. Desde su implantacion utilizamos el metodo de aprendizaje basado en problemas (ABP), uno de cuyos componentes basicos es la reflexion sobre el aprendizaje, que este caso incentivamos con informes de reflexion. En esta comunicacion analizamos 62 informes de reflexion redactados por los estudiantes en varios cursos academicos aplicando tecnicas de analisis cualitativo. Los resultados permiten detectar distintos enfoques en el trabajo y estudio de los estudiantes, asi como fortalezas y debilidades en el trabajo en equipo. Hemos concluido que en nuestro contexto la autorregulacion del aprendizaje se produce tanto individualmente como en equipo, y que el compromiso es un aspecto emocional muy relevante para los estudiantes.

Assessment of an Energy Rehabilitation Cost on a Residential Block proposal. Analysis and Guidelines for Profitability Improvements

Estimated cost of different building technology solutions to carry out a thermal rehabilitation in a residential block of flats is determined in this paper. In recent years the thermal rehabilitation improvements has been the result of the building repairs on facades and/or roofs due to pathologic process. Taking advantages of this maintenance works, the possibility of intervening on thermal materials and systems on the building envelope was presented. In this case the investment was the extra-costs that supposed the insulating materials only (differential cost). Nowadays the rehabilitation sector is growing up with the exclusive aimed to restore buildings considering energy savings. It is necessary to quantify the cost of this interventions motivated by the new regulation framework, to reduce CO2 emissions and to certify existing buildings. The real cost of specific rehabilitation solutions and energy payback period is determined. The estimated annual savings of energy consumption is considered. The results may be useful for developing a framework that clarifies in which cases a rehabilitation of this type is worth.
