“…Studies developed by Oliveira et al (2015) also confirmed the results described in this research, where they found that poultry houses covered with thermoacoustic tiles showed more favorable thermal index values than sheds with metal tile roofing. Silva et al (2015), in evaluating the thermal performance of types of coverings inside reduced models of poultry houses, also inferred that the use of ceramic tiles, when compared to the other tiles tested (fiber-cement and metal), provides better thermal comfort conditions.…”

For studies of thermal performance, computational modeling has been presented as an important decision-making tool to solve complex and everyday problems in poultry production and research. Thus, the present study aimed to validate computational models developed using the EnergyPlus software package and, based on these, evaluate the thermal performance of a poultry house with different types of tiles (thermoacoustic, ceramic, fiber-cement, and metal). The research consisted of two stages: an experimental phase and another phase in which the climatic conditions in four aviary models are numerically simulated, considering different types of tiles. The experimental phase was conducted in two climate seasons, winter (2019) and summer (2020), where air temperature and relative air humidity data were measured and recorded using six HOBO model H12 data loggers distributed inside an aviary located in the semiarid region of Pernambuco state, Brazil. For the computer simulation, a virtual model of the house was developed using the OpenStudio graphical user interface in Sketchup, and the thermal performance was calculated using the EnergyPlus software package. The models were validated, showing a strong correlation between the experimental and simulated data, with Pearson’s correlation coefficient (r) values greater than 0.95. The simulations demonstrated the influence of the roof tiles on the thermal performance of the evaluated building. For the climatic conditions of the semiarid region of the Pernambuco state, thermoacoustic roof tiles presented the best thermal performance, followed by ceramic, fiber-cement, and metal roof tiles.

“…The assumptions of normality were verified using descriptive statistics, with the observance of parameters such as mean, median, standard deviation, interquartile range, asymmetry, and kurtosis measures. Following the protocol established by Oliveira et al (2015), an analysis of variance was performed via the Scott-Knott means test with 95% significance and using the "R" statistical package.…”

The objective of this study was to characterize the thermal environment and evaluate the behavior of finishing pigs housed in deep bedding and conventional systems. The work was carried out in the Department of Animal Science of the Federal Institute of Education, Science and Technology of Southeast Minas Gerais, Rio Pomba campus. Three pens were used in an installation for breeding pigs in their finishing phase. Two pens contained deep bedding, with wood shavings and rice husks. The remaining pen was a conventional system. The behavior of the piglets was observed from 8 a.m. to 5:30 p.m., noting the behaviors with the use of an ethogram, while data relating to the thermal environment in the stalls were automatically collected using data loggers. Thermal environment data for all systems presented thermal stress conditions. Regarding behavioral variables, animals in conventional systems had a higher frequency of visits to feeders, while animals in the deep bedding system were more active and visited the drinking fountains more frequently. Despite the higher level of activity of the animals in the deep bedding system, it is not possible to confirm that the deep bedding provides a better degree of well-being for the animals under thermal stress conditions.

“…Caso não haja conforto térmico, pode-se causar estresse para a ave e queda no desempenho de criação. Como neste modelo de edificação de criação de aves -dark house, a ventilação é controlada por meio de painéis evaporativos e exaustores, sendo que a cobertura tem o papel fundamental nas trocas de calor entre os meios interno e externo, sendo o elemento principal do desempenho térmico do pavilhão (OLIVEIRA et al, 2015).…”

“…Fundamentado neste estudo de Oliveira et al (2015), no qual também foi utilizado o alumínio como material para o telhado, o projeto do pavilhão do presente estudo usou, como cobertura, telhas duplas em alumínio, com uma camada de poliestireno expandido entre elas para melhor isolamento térmico. Além destes aspectos, o alumínio tem a propriedade física de alta reflexão (acima de 80%) dos raios solares (ABAL, 2019).…”

A indústria da construção civil é sinalizada como causadora de impactos severos ao meio ambiente. Diante deste cenário, o desafio é reduzir os agentes causadores de impactos ambientais. Uma forma de atingir resultados positivos nessa tarefa se dá pela substituição de insumos tradicionais, que, em sua maioria, apresentam alto impacto ao meio ambiente, sejam eles materiais de construção inovadores ou alternativos. A Análise do Ciclo de Vida (ACV) permite um diagnóstico sobre o processo produtivo de um produto, analisando não somente a utilização do material, como também toda sua cadeia produtiva, da extração da matéria-prima ao descarte. O objetivo desta pesquisa foi realizar uma análise comparativa do ciclo de vida do alumínio e do concreto como materiais estruturantes em um pavilhão aviário. O método adotado seguiu as recomendações das normas para ACV, as NBR ISO 14040 e 14044. Para a análise dos dados, foi utilizado o programa computacional OpenLCA versão 1.6.3 com a base de dados Ecoinvent versão 3.3, e, para a análise dos impactos, foram empregados os métodos CML e Demanda Cumulativa de Energia (CED). Dentro da fronteira do estudo, que compreende da produção do material ao local de construção, os resultados para a avaliação do inventário do alumínio provaram ser de menor impacto em relação ao concreto. Também foi analisado o uso de energia primária gasta durante o processo de produção com o alumínio e, mais uma vez, seus resultados mostraram menor impacto que o concreto.
