An application of building simulation techniques to the assessment of natural ventilation in office with double skin facade

Milan Janak, Katarina Moravcikova

Abstract: In our paper we describe an application of the building simulation techniques to the assessment of an energy, thermal comfort and natural ventilation effectiveness in the office with a double skin facade. Two distinct building simulation techniques are applied. Firstly, it is a Computational Fluid Dynamics (CFD) technique to assess wind effects on a building façade and to carry out detailed simulation of natural ventilation of an office. Secondly, it is a dynamic building energy simulation coupled with an air flow network model to predict annual performance related to the energy, thermal comfort and natural ventilation. Results of this application simulation study clearly show that a particular design of a double skin façade has a significant negative effect on natural ventilation when compared to the typical operable window. On the other hand results show that with the aid of simulation approach it is possible to identify a construction measures to optimise façade performance.
