Resumo: The objective of this study was to evaluate the thermal conditions inside poultry or cattle sheds made with five types of alternative roof materials and compare with clay tiles, under hot conditions, using the si,ilitude theory and thermal environmental indices. Comparison between the black globe temperature and humidity index, the radiant thermal load and thermal effectiveness provided by the cover at level of the birds or cattle, in general, showed similarity between results. During hot days, the best conditions were associated with clay cover. Initial cost reduction for roof, compared to the clay was estimated to be 47.7% for Reciplac with aluminized coating on the outer and white coating on the inner surface, and 45.5% with the same material except with neutral coating on the inner surface and 41.2% for the roof made of Tetra Pak tiles.

Considerando o Índice de Temperatura de Globo Negro e Umidade, a Carga Térmica Radiante e a Efetividade Térmica propiciados pelas coberturas, ao nível das aves e dos bovinos, verificou-se no geral que ocorreu semelhança entre os resultados e que, no período quente do dia, as melhores condições estiveram associadas à cobertura de barro. Estimou-se redução nos custos iniciais do telhado em comparação ao de cobertura de barro em 47, 7% para o telhado com cobertura Reciplac aluminizada na face superior e branca na inferior, 45, 5 % para o telhado com cobertura Reciplac aluminizada na face superior e neutra na inferior e 41, 2 % para o telhado com cobertura de material reciclado Tetra Pak.Universidade Federal de Viçosa - UFV2011-10-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/23410.13083/reveng.v19i5.261Engineering in Agriculture; Vol. 19 No. 5 (2011); 404-421Revista Engenharia na Agricultura - REVENG; v. 19 n. 5 (2011); 404-4212175-68131414-398410.13083/reveng.v19i5reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/234/182Cardoso, Alaércio de SousaBaêta, Fernando da CostaTinôco, Ilda de Fátima FerreiraCardoso, Virgínia Arlinda da Silvainfo:eu-repo/semantics/openAccess2023-01-19T12:55:17Zoai:ojs.periodicos.ufv.br:article/234Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T12:55:17Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
