“…Another widely applied green construction & building management approach enlightened by life cycle assessment is a green roof, which could generate embodied benefits like eco-system service as a typical nature-based solution by applying green materials and well design. From a life cycle perspective, a naturebased solution could generate additional benefits such as climate risk mitigation, upstream water and energy savings, among others (Busker et al 2022;Cascone 2022;Jacobs et al 2022;Koroxenidis and Theodosiou 2021;Twohig et al 2022).…”

The construction industry is a major user of non-renewable energy and contributor to emission of greenhouse gases, thus requiring to achieve net-zero carbon emissions by 2050. Indeed, construction activities account for 36% of global energy consumption and 39% of global carbon dioxide emissions. Reducing carbon emissions requires adapted government policies, carbon emission analysis and calculation models, and sustainable materials. Here, we review green construction with focus on history, carbon emissions, policies, models, life cycle assessment, and sustainable materials such as biochar, bioplastic, agricultural waste, animal wool, fly ash and self-healing concrete. Analysis of carbon emissions over the building life cycle shows that the construction phase accounts for 20–50% of total carbon emissions. The average ratio of construction phase annual emissions to operation phase emissions is 0.62. We present national policy frameworks and technology roadmaps from the United States of America, Japan, China, and the European Union, highlighting plans to achieve carbon neutrality in the building sector.

“…O atraso térmico (Figura 8c) apresentou valores médios de longo prazo iguais a 3,7 horas (SCOM), 2,6 horas (SC2 e SC4) e 1,8 hora (SOLO). Esses resultados vão ao encontro de observações feitas por outros autores (ALMAAITAH;JOKSIMOVIC, 2022;CASCONE et al, 2018;CASCONE, 2022;PENG, 2012;KOSTADINOVIC et al, 2022), em que se verifica a ocorrência de um atraso temporal nas temperaturas máximas na camada de substrato de telhados verdes. Em longo prazo há uma diferença significativa de atraso térmico de aproximadamente 2 horas, entre os substratos SCOM e SOLO (Tabela 3), demonstrando a influência da composição do substrato na capacidade de atrasar a ocorrência das temperaturas máximas, e o melhor desempenho de SCOM nesse aspecto.…”

Resumo Os substratos de telhados verdes (TV) podem ser aprimorados, buscando melhorar as características térmicas que influenciam na transmissão de calor dessa camada. Este artigo apresenta os resultados de um ano de monitoramento térmico de quatro TVs modulares com diferentes substratos. Os substratos avaliados foram o solo local, substrato comercial à base de turfa e dois substratos alternativos obtidos a partir da adição de biocarvão da casca de arroz carbonizada (CAC) e outros componentes, incluindo resíduos da construção civil. O substrato de solo local apresentou desempenho térmico inferior aos demais substratos com relação a todos os índices térmicos avaliados: amplitude térmica, amortecimento térmico, atraso térmico e taxa de temperatura externa. Os substratos com adição de CAC apresentaram resultados superiores ao solo local e inferiores ao substrato comercial, indicando potencial alternativa a substratos de maior custo, bem como forma de destinar e agregar valor a esse passivo ambiental. Os resultados mostram a importância da escolha apropriada do substrato, de forma a melhorar o desempenho térmico de TVs, bem como a observância do estado de desenvolvimento da vegetação. É apontada a necessidade de estudos para o desenvolvimento de substratos com propriedades que contribuam para o melhor desempenho térmico de TVs.

“…Green roofs, essential in sustainable architecture, are gaining recognition for their role in urban environmental management [5]. These living roofs blend vegetation with structural elements, offering environmental, social, and economic benefits [6,7]. Their integration with BIM represents a new frontier in urban construction, enhancing urban spaces and ecosystem resilience [8].…”

This research delves into the integration of green roofs elements and parameters with Building Information Modeling (BIM), a pivotal advancement in sustainable urban construction. Aligning with the United Nations Sustainable Development Goals, particularly Goal 11, this study explores how this integration can address global challenges like climate change and resource depletion. Using the Dynamo Visual Programming Language within Autodesk Revit, this research develops a computational modeling approach for green roofs, focusing on their thermal and structural characteristics under varied environmental conditions. Key findings demonstrate the significant influence of substrate and drainage material combinations on green roofs’ thermal performance, highlighting the need for tailored designs based on climatic conditions. This study also emphasizes the importance of considering structural performance in both dry and saturated conditions for overall building integrity. This research identifies gaps in current practices, such as limited focus on specific green roof materials and reliance on certain software tools, suggesting the need for broader material selection and software adaptability. Future research directions include expanding material selections, exploring diverse environmental conditions, and integrating green roofs elements and parameters with various BIM software platforms. This study’s implications extend to stakeholders in the construction industry, offering a framework for architects, urban planners, and policymakers to design and implement green roofs aligned with environmental goals. This work contributes to the field by proposing a novel approach to sustainable construction, integrating ecological design with digital technology, and setting a new benchmark in the integration of green roofs design with BIM. By addressing these aspects, this research paves the way for future developments in sustainable urban construction, enhancing the efficiency, sustainability, and resilience of urban communities in line with global sustainability objectives.
