Greening Aspang – Hygrothermische Gebäudesimulation zur Bestandsanalyse und Bewertung unterschiedlicher Szenarien bezogen auf das Innenraumklima.

Abstract: Greening Aspang – Hygrothermal building simulation for analysis and evaluation of various scenarios related to indoor climate. In the research project Greening Aspang [1] measurements were taken from different buildings concerning summery overheating. In the present paper simulations were taken with by „WUFI plus 3.0 dynamic building simulations”. The investigations of the research project serve as a basic for the simulations. The different buildings and its sample flats are explained in detail. The data of the simulation is validated by the measurements and extended to the entire building. The hydrothermal comfort inside the buildings has been investigated and evaluated. It turned out that none of the investigated objects, neither flats nor whole buildings, could satisfy the ÖNORM B 8110‐3 [2]. A comparison between the values of measurements and simulations shows that the simulations are very close to the measured reality. The main difference between this values is, that the measurement values vary in a larger area than the values of the simulation. By means of a variant study the effects of different methods structural measures on the hydrothermal indoor climate during a heatwave is investigated. The different structural measures are exterior shading, airing during the night, change of the colour of the façade, façadegreening and loggiagreening. Each of this structural measures reduce the summery overheating. The most effective one is exterior shading, but the more measures are combined, the better it is. A combination of all leads to the best results. [ABSTRACT FROM AUTHOR]
