1. Estudio experimental sobre el comportamiento térmico de un nuevo tipo de techo-estanque para el enfriamiento pasivo en clima húmedo
In this paper, a new type of metal roof-pond based on indirect evaporative cooling and including confined thermal mass is experimentally evaluated. Five passive cooling systems have been studied with this experimental device. Their characteristic temperatures are analyzed in order to determine the cooling potential in each case and the influence of the therm

2. Análise de métodos para aplicação de ventilação natural em projetos de edificações em Natal-RN
Natural ventilation is an efficient bioclimatic strategy, one that provides thermal comfort, healthful and cooling to the edification. However, the disregard for quality environment, the uncertainties involved in the phenomenon and the popularization of artificial climate systems are held as an excuse for those who neglect the benefits of passive cooling. Th

3. Refrigeração evaporativa por aspersão em telhas de fibrocimento: estudo teórico e experimental
This research focuses the evaporative cooling by water aspersion on wavy cement fiber tiles in the city of São Carlos, SP, seeking to use it to reduce the buildings heat gains. A theoretical model was developed, based on classic equations of fluids mechanic, applied to iterative calculations of heat flows on the tile superior surface, considered as control

4. Comportamento termico de coberturas de fibrocimento em Campinas, SP : aplicação de tecnicas passivas / Thermal behavior of fiber-cement roofing in Campinas, SP : application of passive cooling
In Brazil, the tropical climate is predominant in most of regions. Roofing is the building component with the highest exposition to direct solar radiation. The challenge for researchers and designers is to achieve cornfort in the built environrnent and to contribute to energy saving, proposing roofing systems with good thermal insulation, and consequently le

5. Control of Emergency Cooling Passive Systems of Nuclear Reactors by Bypass Lines / Controle de Sistemas Passivos de Resfriamento de Emergência de Reatores Nucleares por Meio de Linhas de Desvio
Neste trabalho são apresentados resultados experimentais, de um circuito operando em circulação natural, que permitem analisar o comportamento de um sistema de resfriamento de emergência quando é aberta uma linha de desvio entre a fonte quente e a fonte fria. O trabalho tem ainda a importância de documentar os testes de caracterização hidráulica do
