Geração distribuída em edifícios de multi-unidades residenciais: uma revisão bibliográfica sobre as novas possibilidades de mercado

Abstract

Distributed generation (DG) in multi-unit residential buildings has been gaining increasing interest in the energy market, driven by the growing demand for renewable sources and sustainable solutions. In this context, the objective of this research is to provide an updated literature review on DG in multi-unit residential buildings. To achieve the proposed objective, a bibliographic review methodology was employed. Initially, articles of greater importance were selected and analyzed using tools such as Elsevier, Scopus, and Google Scholar. A total of thirty scientific articles were reviewed, selecting publications from 2019 onwards. The benefits and challenges of distributed generation in multi-unit residential buildings are discussed. Key benefits include energy cost savings, economic viability, and improved energy supply reliability. Major challenges include upfront costs, regulatory issues, planning, and lack of awareness. Among the analyzed articles, terms related to challenges, technical aspects, and economic aspects were mentioned 36, 24, and 24 times, respectively. However, the research revealed that benefits were mentioned more frequently, representing 56% of the total citations. In absolute numbers, 108 instances of references to benefits were identified. Of the selected scientific articles, 10% addressed barriers and difficulties, providing an in-depth understanding of the obstacles faced in implementing concepts and technologies. Additionally, 27% of the articles explored the theme of Building Integrated Photovoltaics (BIPV), highlighting advancements and applications in buildings. The reviewed articles also discuss the growth prospects of DG in multi-unit residential buildings. Due to the rising electricity prices and the associated environmental benefits of DG, it is likely that distributed generation will continue to grow in popularity in the coming years.
