Avaliação da relação entre ampliabilidade e consumo energético em habitação de interesse social: atributos facilitadores da resiliência

Abstract

Faced with millions of social housing delivered by the State, we realize that the projects are not very resilient and respond minimally to the needs of each family, a model that is repeated from north to south of the country, disregarding its climatic and cultural variations. That said, resilience in the built environment, in this work, is understood as the physical and social ability to adapt to impacts and incident vulnerabilities, that is, the ability of the building and the people who live in it to transform positively in the face of impacts. In this context, expandability can be considered a facilitator of resilience. However, interventions in social housing happen, to a large extent, without the guidance of professionals and, for the most part, do not provide better quality housing. These expansions, in some cases, imply the compromise of lighting and natural ventilation, consequently causing alcoves, which indicates the need for air conditioning and artificial lighting during the day, actions that signal greater energy consumption. Therefore, this research focuses on the user/resident, as it sought to understand the main impacts, vulnerabilities and adaptive capabilities in the built environment from their perspective. The main objective of this work was to develop a set of methodological assessment procedures (artifact) to identify incident impacts on the built environment and a resilience assessment procedure. Subsequently, this work evaluated the relationship between expandability and energy consumption in social housing, analyzing the relationship between expansions not guided by professionals with a higher energy consumption, resulting from thermal and luminous discomfort in a case study, located in the city of Uberlândia- MG. It is expected to contribute to more qualified and efficient housing, indicating possible solutions for expansions, in search of an awareness of the importance of quality interventions, thus promoting resilience. For this, as a methodological approach, we used the Hypothetical-Deductive method supported by Design Science Research, structured in: (i) bibliographic research - state of the art and literature review; (ii) reference research - case-control analysis; (iii) conceptual research - presents the intended concepts and theories; (iv) empirical research - analytical, post-occupational and morphological study in a case study; (v) purposeful research - artifact development. Thus, after the development and application of the artifact, considering the variables examined here and in view of this clipping, we can conclude that there are strong indications of the relationship between expansions not guided by professionals and greater energy consumption. This research is part of a larger research entitled “[BER_HOME] Resilience in the Built Environment in Social Housing: technologically advanced assessment methods”, which has as main objective to evaluate the factors that constitute resilience in the built environment in social housing with focus on the housing unit, conducted by the [MORA] Group - Housing Research at FAUeD/UFU.
