During the lifecycle of a building, it consumes a significant amount of energy. According to contemporary
researches almost 40% of the energy produced by humanity used for building constructions, maintenance
and demolitions. (Pérez-Lombard et al., 2008) The HVAC – heating, ventilation and air conditioning are
even standing out from the above-mentioned category. (Chenari et al., 2016) Papers are already proving
that natural ventilation can be a good solution for moderating the energy demand of buildings. (Chen et
al.) The study presents different geometry variations in a passive air conduction system based on two
wind towers which are responsible for the ventilation and comfort level of a new winery in Hungary. The
topology was developed after aerodynamic experiences and was investigated via CFD – computational
fluid dynamics – simulations. The results proved that this method can reduce the construction costs, by
selecting the simplest acceptable type which also efficient enough to achieve remarkable energy and
costs savings during its lifetime.
