“…• in the first phase, the thermal characterization of the HOMEDONE reinforced-EPS panels is carried out by measuring the in situ thermal transmittance of an experimental unit, in order to complete available literature data and to provide a reference for future analytical and numerical simulations, which are essential to define the correct strategy for the improvement of the system hygrothermal/comfort performance; • in the second phase, since a modular and dry construction system may suffer from air leakages [27], and since airtightness performance are essential for future energy and comfort numerical simulations, a characterization of the system in terms of airtightness is also carried out through the fan pressurization method ("Blower Door Tests"); • in the third phase, the indoor hygrothermal behavior of the experimental unit is measured during the spring and summer seasons, while any possible internal condensation issue is identified; • then, considering the issues observed during the third phase (very high indoor air RH due to internal surface condensation), hygrothermal dynamic simulations are carried out to verify and quantify the occurrence of moisture-related issues such as condensation and mold growth risk during annual occupancy, also extending the results to a wider range of climatic contexts; • finally, hygrothermal simulations are carried out to demonstrate the possibility of preventing moisture-related issues through the addition of an internal layer with moisture buffering capacity in all the considered climatic scenarios.…”

International housings are categorized into light weight (ACH50 4.91 1/h), cavity wall envelope (ACH50 5.39-14.90 1/h), and precast concreate and timber-framed houses (ACH 1.69 1/h) [39,40,43]. Timber housings are categorized into light timber frame (ACH50 3.38-23.50 1/h), post and beam (ACH50 5.91-10.55 1/h), and log house (ACH50 78.68 1/h) [42].…”

An investigation was conducted into temporary modular housing for use in disaster areas to assess the feasibility of energy independence. Flexible modular units have been proposed as a temporary housing solution in disaster areas, as they can be deployed in combination with energy units across a wide range of environments. A dynamic energy simulation was used to examine the heating/cooling requirements and the potential photovoltaic power generation of such modular housing in an East Asian climate. This was used to assess the potential for energy independence. The building performance was analyzed based on measurements of airtightness, insulation performance, and thermal bridge phenomena taken from mock-up modular housing. According to the wall assembly method, it was confirmed that the airtightness performance was poor. Further investigations explored the possibility of reducing the annual heating/cooling loads by improving the airtightness, which would contribute to greater energy independence. In general, the specific housing needs of different victim groups can easily be satisfied through the application of different modular unit combinations.

“…No Brasil, existem estudos sobre a logística do contêiner no transporte de mercadorias, como o trabalho de Lopes, Beltrame e Beltani (2017) e o estudo de Sousa (2016), mas existem poucas publicações sobre o uso do contêiner como moradia. Tem-se exemplo de trabalhos que contemplam o reuso de contêineres na construção de edifícios comerciais (CARBONARI; BARTH, 2015).…”

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.
