Title:
Abstract:	Für das Konzept der ersten Plusenergie-Produktionsstätte in Ungarn wurde besonderes Augenmerk auf die natürliche Lüftung des Gebäudes mit passiven Lüftungstürmen gelegt. Mit dem Ziel, die planerischen Ansätze nachvollziehbar prüfen zu können, wurde ein vierstufiger Algorithmus bestehend aus gebäudeaerodynamischen Untersuchungen in Form von Berechnungen, Windkanaltests, CFD-Simulationen und Messdatenerfassung im Gebäude entwickelt. Durch diese “Validierungsplattform“ können nicht nur nachgewiesene Aussagen über den aerodynamischen Charakter eines Gebäudes getroffen, sondern auch der Einfluss von Änderungen während der Planung und Ausführung sicher quantifiziert und bewertet werden. Darüber hinaus bewirkt die aerodynamische Optimierung eine Verbesserung der Behaglichkeit und Verringerung des Energieverbrauchs. Building aerodynamic investigations for an energy-plus production facility in Sikonda (Hungary). The concept of the first energy-plus production facility in Hungary, which was developed with Energy design method, consists in an essential design approach: the natural ventilation with passive ventilation towers. With the objective of generating comprehensible diagnosis to different design solutions, it was necessary to create a four-level aerodynamic analysis algorithm consisting of calculations, wind tunnel tests, CFD simulations and measurements in buildings. This “validation platform” ensures not only proofed conclusions about the aerodynamic character of a project, but also quantifies in an accurate way the effect of modifications during planning and construction. In addition, the consequence of this aerodynamic optimization of the built environment is the improvement of the indoor comfort and well being as well as the reduction of energy consumption.
