1. Numerical simulation of wind-driven ventilation of a three-generic low-rise building in various geometrical configurations
Resumo A ventilação natural é a principal estratégia passiva para a obtenção do conforto térmico no interior das edificações, além de promover a renovação do ar ambiente, tornando-o mais saudável. Nas últimas décadas, a Dinâmica dos Fluidos Computacional mostrou-se uma ferramenta eficiente para estimar a ventilação natural. Diante disso, o

3. Post-Occupancy Evaluation of an educational building: Case study of the ETS-UESC Building
Abstract The physical and environmental conditions of educational institutions are determining factors for occupant comfort. The Post-Occupancy Evaluation (POE) presents itself as a methodology for verifying environmental aspects in full use, considering the technical criteria and the users' perception. This article discusses the particularities of the ETS-U

4. Implementation of ventilation towers in a greenhouse established in low altitude tropical climate conditions: numerical approach to the behavior of the natural ventilation
ABSTRACT Deficient ventilation rates and airflow patterns in naturally ventilated greenhouses are the main causes for the generation of inadequate and heterogeneous thermal conditions inside this type of structure. In this research, a numerical study was developed using a two-dimensional computational fluid dynamics model validated in a Colombian greenhouse

5. PERFORMANCE AND WELFARE OF FINISHING PIGS SUBJECTED TO CLIMATECONTROLLED ENVIRONMENTS AND SUPPLEMENTARY LIGHTING
ABSTRACT An adequate thermal environment in pig farming facilities is essential to ensure productivity and animal welfare. The objective of this study was to evaluate the behavior and performance of finishing pigs, subjected to climate-controlled environments and supplementary lighting. Twenty-seven pigs (3/4 Duroc, 1/4 Pietrain) were kept in pens with no cl

6. Factors Affecting Broiler Production: A Meta-Analysis
ABSTRACT The meta-analysis data were obtained from a survey of published articles over 15 years. The data were selected to classify the factors that impact broiler production and separated by influence aspects of animal production (thermal environment and other factors). The relevant data for each study were systematized, grouped and later tabulated and inse

7. Shoot proliferation, leaf anatomy and pigment content of Eugenia dysenterica growing in conventional and natural ventilation systems
ABSTRACT Natural ventilation micropropagation systems differ from conventional systems by allowing gas exchange between the internal and external media of the culture flask. The objective of this work was to compare the conventional system of in vitro propagation of Eugenia dysenterica (Mart.) DC. with a natural ventilation system. For shooting, explants wer

8. Study of natural ventilation in a Gothic multi-tunnel greenhouse designed to produce rose (Rosa spp.) in the high-Andean tropic
Resumo Nas regiões tropicais, a produção de plantas ornamentais é desenvolvida exclusivamente em estufas plásticas ventiladas de forma natural, o que significa que em algumas ocasiões microclimas inadequados são gerados com altas temperaturas e umidade que limitam o desenvolvimento produtivo das plantas. O objetivo deste trabalho foi estudar os fluxos

9. Plumas em escoamento uniforme com estratificação de duas camadas
RESUMO Plumas ocorrem quando um fluido é descarregado em outro fluido com densidade diferente, como poluentes na atmosfera. Neste trabalho, desenvolveu-se um estudo experimental em um tanque de água e modelagem matemática usando a abordagem integral com o intuito de investigar o escoamento gerado por plumas salinas em escoamento uniforme e com estratifica

10. Avaliação de modelos preditivos de conforto térmico em escritórios no clima subtropical brasileiro
Resumo O objetivo deste trabalho é comparar as respostas subjetivas de usuários de escritórios localizados no clima subtropical brasileiro, ao longo das quatro estações climáticas, com os modelos de conforto térmico (analítico e adaptativo) da ASHRAE 55 (2017). Estudos de campo sobre conforto térmico foram realizados em quatro edificações de escri

11. SIMULATION OF VENTILATION SYSTEMS IN A PROTECTED ENVIRONMENT USING COMPUTATIONAL FLUID DYNAMICS
ABSTRACT Computational simulations of mass and energy flow help in implementing alternative cooling systems in protected environments. The aim of this study was to model and simulate the interaction between external and internal environments of a protected environment by means of computational fluid dynamics (CFD) techniques and validate micrometeorological

12. Numerical study of the influence of internal heat source in naturally ventilated offices
Abstract The natural ventilation in a building performs a fundamental role in users' welfare and health, when used as a bioclimatic and architectural strategy, it can provide brighter projects. Increasing the indoor air speed ventilation has an important performance maintaining indoor air quality, contributing to thermal interactions between human body and e
