“…A solar water heating system was considered an energy efficiency measure. This system is the most common water heating system in Brazilian social housing [8,23,24]. Furthermore, the electricity consumption for water heating in the representative model was significant (see Section 3.2).…”

Several studies have shown that social housing in Brazil usually fails to provide thermal comfort to its occupants. This study aimed to define energy efficiency measures for a representative social housing model to, together with local production of renewable energy, achieve the nearly zero-energy target. The thermal performance and energy efficiency of the representative model were evaluated using computer simulation, considering the southern Brazilian climatic context. An analysis of the economic feasibility of energy efficiency measures was also carried out. The results showed that the nearly zero-energy model with energy efficiency measures on the envelope (EPS and gypsum board in the external walls and rock wall in the roof) and a solar water heating system reduced 13.1% of the annual primary energy consumption in comparison with the representative model. Considering the renewable energy generation in the nearly zero-energy building, the electricity consumption was 38,777.6 kWh/year lower than that in the representative model (57.0% reduction). The economic analysis of the energy efficiency measures indicated a positive net present value and a payback of nearly six years. It was concluded that using energy efficiency measures and an on-site renewable made it possible to reach the nearly zero-energy target in a representative social housing model.

“…By applying the same case studies in different climatic regions, it would be possible to quantify the impact of each parameter when subjected to specific conditions. Based on this, studies on the cost of these measures can help designers and builders choose the most cost-effective adaptations for their buildings [8].…”

“…O projeto de uma edificação desempenha um papel fundamental na influência do desempenho térmico. Diversos elementos e decisões projetuais podem afetar o comportamento térmico de uma construção como, orientação solar, design da envoltória, ventilação, proteção solar, coberturas, paredes e planejamento do layout (BAVARESCO et al, 2021).…”

A eficiência energética em edificações é uma questão fundamental para a sustentabilidade e para a economia de recursos. Existem diversas estratégias para aumentar a eficiência energética em edificações, desde a escolha de materiais até a utilização de fontes renováveis de energia. O objetivo deste artigo é analisar a eficiência energética de uma edificação construída totalmente em concreto armado moldado in loco em relação a uma edificação construída com paredes de alvenaria convencional, de mesma espessura através de uma ferramenta nativa de verificação do Archicad 25. Assim, foi possível modelar uma edificação e executar a simulação energética a fim de obter resultados comparativos preliminares. Os resultados apresentam uma pequena diferença energética entre as paredes da edificação, onde a parede de concreto moldada in loco apresentou maior eficiência energética em relação a parede de alvenaria. A simulação apontou menor consumo energético para aquecimento na edificação com as paredes de concreto, também, apresentou menor consumo energético para refrigeração das paredes de alvenaria. Ainda, ao analisar as temperaturas internas dos ambientes, tanto para mínimas quanto para máximas, o projeto com as paredes em alvenaria atingiu pontos extremos, necessitando um maior consumo energético para estabilizar a temperatura ambiente, no objeto onde as paredes foram projetadas em concreto armado, a diferença do número de horas para aquecimento no ano foi de 191 horas em relação às paredes de alvenaria e para refrigeração as paredes de alvenaria tiveram a diferença de 74 horas, para esse mesmo período em relação as paredes de concreto armado moldadas in loco.

“…Strategies and models to achieve thermal and energy performance are presented. Meta-models, simulations (ROSSI et al, 2019;KRÜGER;LAROCA, 2010), laws, photovoltaic panels, and solar water heating are the main strategies tested to enhance energy efficiency in SH (PINTO; AMARAL; JANISSEK, VALE et al, 2017;SASSI, 2015SASSI, , 2018DA SILVA, 2017;MORENO;MORAIS;SOUZA, 2017;NUNES et al, 2020;BAVARESCO et al, 2021). Although those strategies contribute to the general goals of sustainability issues and climate change control, most of them require a high initial investment to be implemented.…”

Housing transformations and their impacts on the well-being of dwellers

Housing transformations have been studied over time. Numerous Post-Occupancy-Evaluation (POE) studies reveal user-initiated alterations occurring in Brazilian Social Housing (SH). These transformations have specific objectives, such as additional space, refurbishment, and improvement, or upgrading. However, results of transformations are not always positive, and may affect dwellers’ well-being through losses in environmental comfort. A critical investigation using the Systematic Literature Review (SLR) method analysed forty-seven studies to understand what needs and requirements stimulate SH projects' upgrading and how transformations impact well-being. In addition, an in-depth analysis was made to assess aspects of environmental comfort, safety, design, layout and economic aspects that affect people’s well-being, and improve their quality of life. Results contribute to supporting upgrading processes of existing SH and to guide the improved design of new SH projects based on the desires and well-being requirements of low-income families.
