The construction industry’s pursuit of eco-friendly materials has sparked interest in bamboo, a renewable resource with exceptional physical and mechanical properties. This study analyzed the integration of Dendrocalamus giganteus bamboo with phase change materials (PCMs) to enhance thermal energy storage in building applications, aiming to improve temperature regulation and reduce energy consumption for climate control. The study compared the performance of bamboo impregnated with an industrial PCM or coconut oil, used in conjunction with a polyurethane resin (PU) coating treatment, assessing their thermal regulation performance against traditional building materials such as ceramic tiles, fiber cement, and metal sheets. From an anatomical perspective, the pores within bamboo culms offered ample space for PCM storage, resulting in a substantial heat storage capacity. Thermal behavior tests conducted in a wind tunnel revealed that the impregnated bamboo samples effectively mitigate temperature fluctuations by aligning them with the PCM’s phase change temperature. Additionally, it was observed that air flow velocity had an impact on this phenomenon. The study concluded that bamboo culms impregnated with PCM hold promise for temperature regulation in construction applications, with variations in airflow exerting an impact on the outcomes obtained.

Esta pesquisa teve como objeto de estudo o Jardim Botânico da Universidade Federal de Juiz de Fora (UFJF). A partir dos conceitos da psicologia ambiental implicando a Teoria da Restauração da Atenção (TRA), o estudo teve como objetivo analisar a percepção dos visitantes que disponibilizaram comentários públicos na plataforma digital Google Avaliações, sendo filtrados com base na técnica de análise de conteúdo (AC) de Bardin (2011). Assim, a pesquisa exploratória e descritiva utilizou suporte da ferramenta Voyant Tools (2025) online para o processamento dos dados visando uma análise textual a partir da nuvem de palavras Cirrus e da análise chamada de Link. Os resultados baseados num corpus textual formado por (n=813) comentários revelaram que o Jardim Botânico da UFJF é amplamente percebido como um espaço que promove contato com a natureza, cumprindo com critérios associados à teoria em tela sobre os ambientes restauradores. Por fim, uma agenda propositiva, que oferece subsídios tanto para planejadores e gestores, quanto para pesquisadores e demais interessados, foi criada com quatro focos principais: (1) Recuperar a atenção; (2) Aliviar o stress; (3) Contribuir para a qualidade de vida; (4) Combater a sazonalidade a partir dos usos do Jardim Botânico da UFJF. Futuros estudos podem a ampliar o desenho metodológico incluindo dados primários aferidos por questionários e entrevistas, o que pode contribuir para se analisar um aspecto importante da TRA o papel das histórias individuais para a interação simbólica que ambientes restauradores podem suscitar.

This research had as its object of study the Botanical Garden of the Federal University of Juiz de Fora (UFJF). From the concepts of environmental psychology implying the Attention Restoration Theory (ART), the study aimed to analyze the perception of visitors who made public comments available on the digital platform Google Reviews, being filtered based on Bardin's (2011) content analysis (CA) technique. Thus, the exploratory and descriptive research used the support of the Voyant Tools (2025) online tool for data processing aiming at a textual analysis from the Cirrus word cloud and the analysis called Link. The results based on a textual corpus formed by (n=813) comments revealed that the UFJF Botanical Garden is widely perceived as a space that promotes contact with nature, complying with criteria associated with the theory in question about restorative environments. Finally, a purposeful agenda, which offers subsidies both for planners and managers, as well as for researchers and other interested parties, was created with four main focuses: (1) Recovering attention; (2) Relieve stress; (3) Contribute to the quality of life; (4) Combat seasonality from the uses of the UFJF Botanical Garden. Future studies can expand the methodological design to include primary data measured by questionnaires and interviews, which can contribute to analyzing an important aspect of ART: the role of individual stories for the symbolic interaction that restorative environments can elicit.
