28. Absortancia solar de superficies opacas : metodos de determminação e base de dados para tintas latex acrilica e PVA / Solar absorptance of opaque surfaces : a determination methods and data base for latex acrylic and PVA coatings
Solar radiation is the main responsible factor for the thermal load of buildings, and its impact over this load depends, mainly, on the solar absorptance of the building envelope. The lack of reliable and current data implies that researchers and specialists use visual perception or adopt tables based on surface colors to quantify the solar absorptance, whic

29. Correlation between Indoor and Outdoor Human Thermal Preferences: A Study of the 55-2004 ASHRAE Standard Method / Relações entre preferências térmicas humanas no interior de edificações e as temperaturas externas: um estudo sobre o método adotado na norma AHSRAE 55-2004
Thermal comfort is specifically related to thermal behavior in response to both indoor and outdoor air temperature. Human thermal acceptability to climate changes and its effects depend on several aspects. It relies not only on local climatic conditions, but also on personal traits which can interfere seriously with thermal preferences as well as with someon

32. Avaliação do desempenho térmico de vidros refletivos: estudo de caso em células - teste / Evaluation of the thermal performance of reflective glasses: study of case in test-cells
The glassed surfaces are so fragile concerning gain of heat, allowing the easy entrance of solar radiation in the interior of buildings. The proportion between glassed surfaces and opaque ones of a building is a decisive factor in the environment comfort, as the big glassed areas used without criterion are the principal responsible for the gain of heat in th

36. Evaluation of mixed-mode application for thermal load reduction in office buildings at the cities of São Paulo and Rio de Janeiro / Avaliação da aplicação do modo misto na redução da carga térmica em edifícios de escritórios nas cidades de São Paulo e Rio de Janeiro
Diante das atuais questões ambientais, o uso eficiente da energia é uma premissa em todos os setores de atividades. Sabe-se que as edificações são grandes consumidores de energia e boa parcela desse consumo se dá em sistemas de condicionamento artificial. São três os principais fatores que atuam no balanço térmico e influenciam esse consumo: arquit
