CFD modeling and simulation of ventilation in the Evandro Sena Freire Building

Abstract

The Evandro Freire building is a student complex that depends entirely on air conditioning to guarantee minimum environmental comfort conditions. This situation led to this research regarding the improvement by taking incident natural ventilation advantage, energy efficiency evaluating proposals to improve building permeability. It began with the surroundings assessment, topography, adjacent occupation and terrain roughness, to verify the turbulence generated degree over the winds natural flow using the CFD model (computational fluid dynamic simulation) and GIS. The residual value on the building was used to evaluate several passive and active wind distribution building systems. The ventilation effects on the building temperature of the different systems in the building physical spaces were evaluated and compared with the ambience parameters.
