1. Study using a CFD approach of the efficiency of a roof ventilation closure system in a multi-tunnel greenhouse for nighttime microclimate optimization
ABSTRACT The thermal efficiency of naturally ventilated greenhouses is limited due to the permanent exchange of air through the vents, especially during the night hours. The objective of the work consisted in evaluating a system of inflatable air ducts that close the roof vents during the night as a strategy to reduce the energy loss during these hours. For

2. Avaliação do potencial de uso de três espécies vegetais como cobertura leve de telhados em edificações / Evaluation of the potential use of three plant species as light cover on roof buildings
O uso telhados verdes oferece benefícios como: moderação dos valores da temperatura no interior de edificações e contenção temporária da água de chuva, limpeza de poluentes atmosféricos, além de favorecer aspectos ecológicos. Poucos estudos científicos foram realizados no sentido de adaptar as técnicas contemporâneas e a indicação de espéci

3. Thermal performance of a castor oil foam as insulating material inside the roof : study case in the city of Ilha Solteira, Brazil / Desempenho termico da espuma poliuretana a base de oleo de mamona utilizada em componentes da edificação (subcoberturas) : estudo em Ilha Solteira, SP
The aim of this work is to describe an experimental study using castor oil foam as an insulating material inside the roof. The castor oil foam inside the roof is an appropriate natural recycled material as a passive cooling strategy as opposite to the burning of fossil fuels for air conditioning (AC) and mechanical ventilation. The expected result of this re

4. Equações preditivas para determinar a temperatura interna do ar: envolventes em painel alveolar com cobertura verde / Equations to determine the internal temperature of the air: walls and ceiling build from panels of alveolar concrete with green roof
Introduction: Using a statistics tool called multiple linear regression, we created equations for predicting the indoor temperature in a building with walls and ceiling build from panels of alveolar concrete, with a green roof system. Explanation: Predictive equations enable simulations of indoor temperatures of buildings using a small number of data and wit

6. Análise do comportamento térmico de uma cobertura verde leve (CVL) e diferentes sistemas de cobertura / Analysis of the thermal behavior of an extensive green roof and different roof systems
The present research main objective was to experimentally analyze the thermal behavior of an extensive green roof system and also to compare different roof system thermal behavior, considering their thermal profits in the period of transition between the stations spring-summer, in the city of São Carlos-SP. The roof systems analyzed were: 1) galvanized stee

7. Desempenho térmico de cobertura verde utilizando a grama Brachiaria humidicola na cidade de São Carlos-SP
This work aims to analyze the thermal behavior of a green roof with the Braquiária grass (Brachiaria humidicola), that reaches 1m height, comparing it with a traditional roof (concrete slab on show). Considering temperature and relative humidity data obtained through field measurements in different months, the thermal performance of the green and traditiona

8. Thermal performace of glasses in building construction: study in test-cells / Desempenho termico de vidros utilizados na construção civil : estudo em celulas-teste
Thermal performance of buildings depends on several factors, such as implantation, orientation, materials and building components, which should be appropriately defined for different climate conditions. The building acts as a controller of the climatic variables, through the building envelope (walls, floor, roof and openings) and the nearby elements. Buildin

9. InteraÃÃo entre fatores climÃticos e um recinto localizado na cidade de recife: estudo teÃrico-experimental
Ambient temperatures lying between medium and high values, combined with small thermal amplitude, high values of relative humidity and solar radiation make the city of Recife a region that can be considered as having scarce possibilities for the use of passive or low energy consumption methods for providing thermal comfort conditions in local residences.

10. Desenvolvimento e avaliação de um sistema de resfriamento evaporativo, por aspersão intermitente, na cobertura de aviarios usando modelos de escala distorcida
Technical poultry production is presently requiring more environmental control on the thermal cornfort characteristics because of the use of high potential genetic birds, diets energy high levei, and an increase of birds density. The general objective of this research was to develop a system for roof cooling based on the evaporative cooling concept, using in
