13. Avaliação termo-energética de um edifício segundo critérios de prédios verdes
A construção civil é um dos setores que mais consome recursos naturais no mundo. Desde a extração da matéria-prima até a conclusão da obra, os edifícios utilizam grande parte da ener-gia produzida no planeta. Durante sua vida útil o gasto com energia também é alto e há uma grande produção de lixo proveniente dos moradores e da realização de

15. Desenvolvimento de bloco de vedação com barita na composição de partida para blindagem de radiação X
This work main objective is to study the use of bricks in barium X-rays rooms in order to contribute to the optimization of shielding rooms diagnosis. The work was based on experimental measurements of X-ray attenuation (40 to 150 kV), using ceramic seal bearing the incorporation of barium sulfat (BaSO4). Different formulations were studied in three differen

16. SENSORIAMENTO REMOTO APLICADO AO ESTUDO DO COMPORTAMENTO ESPECTRAL DA ÁGUA NO RESERVATÓRIO PASSO REAL RS / REMOTE SENSING APPLIED TO THE STUDY ON WATER SPECTRAL BEHAVIOR IN PASSO REAL RS RESERVOIR
The building of reservoirs for energy generation and water flow control generated river environmental changes as well as modifications on fluvial environment. In such context, remote sensing is a tool that enables spatial analysis and temporal aquatic environmental information acquisition. This research present a study on water spectral behavior in Passo Rea

20. Simulação de sistemas de climatização combinada à simulação higrotérmica de edificações
Due to the nonexistence of a building simulation program that can simulate in details the combined heat, vapor and liquid transfer in porous elements and the HVAC systems, a generic and flexible computational algorithm has been elaborated in order to integrate models for both HVAC systems and multizone building models. In that algorithm, mathematical models

21. Insertion of buildings simulation into architectural design teaching : methodology proposal / Inserção de simulação computacional de conforto ambiental de edificios em ensino de projeto arquitetonico : proposta de metodologia
In architectural design teaching at undergraduate fevel in Brazil, environmental comfort and energy efficiency have been traditionally kept as separate knowledge domains, which reflect on the poor quality and high consumption of the built environment. It is proved then the necessity of insertion of a methodology or tools to be applied in education. As a way

24. Modelagem da transferência de calor combinada por condução e radiação em isolantes térmicos de edificações
New insulation materials are being used in building industry to reduce electric energy consumption due to presence of HVAC (Heating, Ventilation and Air Conditioning) systems or to improve the thermal comfort of non-conditioned environments. An insulation material used in ceilings is the glass wool. The glass wool is considered as a semitransparent material,
