“…The thermal conductivity values of the samples are tabulated in Table 2, where conductivities of the EC-PCM40, EC-PCM40-CNF2, and EC-PCM40-BN10 were noted as 0.293, 0.303, and 0.415 W·mK −1 [8], whereas the densities were estimated as 0.85, 0.84, and 1.03 g·cm −3 , respectively. The addition of the conductive agents resulted in higher thermal conductivity resulting in an enhancement of 3.3% and 41.6% for the CNF and BN filler, respectively, and the values are comparable with other reports for similar filler makeup [16]. Studies with poly (imide) matrix and 10 wt.% BN filler have reported a thermal conductivity of~0.26 W·mK −1 [36], whereas paraffin matrix material and 10 wt.% BN nanosheets filler have reported a thermal conductivity of~0.48 W·mK −1 [37].…”

“…Due to their low weight, quick assembly, low cost, and versatility, portable containers are also currently used in a wide variety of applications, from housing after natural disasters to military operations. There is a large market that exploits diverse construction techniques, offering solutions ranging from single-family homes to blocks of different floors or offices [16]. Within the armed forces, maritime shipping containers have been used as field hospitals, ammunition warehouses, sanitary warehouses and drinking water treatment plants, among others [17,18].…”

This manuscript integrates the experimental findings of recently developed epoxy-phase change material (PCM) formulations with modeling efforts aimed to determine the energy demands and savings derived from their use. The basic PCM system employed was composed of an epoxy resin, a thickening agent, and nonadecane, where the latter was the hydrocarbon undergoing the phase transformation. Carbon nanofibers (CNF) and boron nitride (BN) particulates were used as heat flow enhancers. The thermal conductivities, densities, and latent heat determined in laboratory settings were introduced in a model that calculated, using EnergyPlus software, the energy demands, savings and temperature profiles of the interior and the walls of a shelter for six different locations on Earth. A shipping container was utilized as exemplary dwelling. Results indicated that all the epoxy-PCM formulations had a positive impact on the total energy savings (between 16% and 23%) for the locations selected. The use of CNF and BN showed an increase in performance when compared with the formulation with no thermal filler additives. The formulations selected showed great potential to reduce the energy demands, increase savings, and result in more adequate temperatures for living and storage spaces applications.

“…Sendo assim, geralmente estas habitações não envolvem instalações essenciais e, portanto, não fornecem uma resposta ambiental adequada aos usuários (FÉLIX; BRANCO; FEIO, 2013). Este tipo de construção tem sido utilizada também como postos militares, banheiros públicos e quiosques (PEÑA;SCHUZER, 2012;ELRAYIES, 2017).…”

A construção civil passa atualmente por desafios em construir de forma mais econômica e ambientalmente correta. Neste trabalho visa-se conhecer melhor o equipamento não convencional utilizado para edificações, o contêiner, avaliando seu desempenho térmico. O contêiner é escolhido como objeto de estudo pois é um módulo que pode ser adaptado para diversos tipos de climas, terrenos e construções. E como no Brasil sua utilização na construção é recente, torna-se necessário uma análise para entender como adaptá-lo de forma eficiente. Neste estudo, a avaliação do desempenho térmico do contêiner é feita via simulação numérica utilizando o programa Energyplus, analisando o impacto da ventilação natural e da massa térmica dos fechamentos no comportamento térmico da edificação. São consideradas as condições climáticas para as zonas bioclimáticas 2, 3 e 8, que englobam o litoral brasileiro, previstas na norma NBR 15.220-2005, observando também os requisitos mínimos da norma NBR 15.575-2013. Para o estudo, projetou-se uma casa com dois módulos de contêiner, totalizando uma área de 29,57 m². Os resultados obtidos mostram a necessidade de adaptações para que o contêiner possua habitabilidade em todas as zonas bioclimáticas analisadas. Constata-se que o uso de isolamento térmico nos fechamentos verticais, de uma cobertura termicamente eficiente, de uma fundação adequada e de cores com tons mais claros no fechamento externo proporcionam um melhor desempenho térmico à edificação, para os climas analisados.

A decrease in the elastic modulus and yield strength due to the creep process is the changes contained in the material that is burning. One strategy to counter this is by using passive fire protection systems. The system is built into the structure to control the fire by using building materials and does not require any special operations in the event of a fire. This study is a review of a new study of passive fire protection systems. This research report contains a review regarding the preliminary study of the manufacture of fireproof new materials from industrial waste that is economical and environmentally friendly. Manufacture of new materials is made to overcome deficiencies in fire-resistant material that exists today. The purpose of this study is to analyze experimental factors, which are influence the making of experimental new fireproof material that is smart and innovative materials for civil engineering. Geopolimerization method that is used in this study comes from the development of brick manufacturing method as one of the fire-resistant material that exists today. The main results of this study are the major factors that influence the making of pasta geopolymer as passive fire protection. The discussion will be related to the elements of determinant manufacture of fire-resistant geopolymer paste. The conclusion is factors that supporting the manufacture of new fire-resistant material with geopolymer method.
