Wind and Air Flow Studies

Changes in climate have various implications for building design, construction and maintenance.In the framework of the CLAVIER project a case study has been implemented in Tatabánya to assess the structural impacts and vulnerability on the roof, particularly in point of the wind loads.A classification of building stocks were made in three main groups (dwellings; industrial/ commercial buildings; public buildings) and 16 different types were defined representing almost the 90% of Hungarian building stock.The methodology of the assessment of the vulnerability: after estimating the sensitivity to meteorological conditions of each type of building attributed to roof covering material, building's age, roof area etc. we determine the exposure to the wind speed changed caused by the global warming.The indexes of building type's adaptive capacity depends on the attitude and socio-economic situation of house's owners related to mobility, risk prevention, potential to mitigate the damage costs etc.According to our results almost the half of the dwelling categories is attributed higher than average vulnerability.Obsolete block of flats (which are relatively prevalent in Tatabánya), churches and older, dilapidated public buildings are the most endangered.It is obvious that those areas where the block of flats from 1945's and the high-rise prefabricated housing blocks dominate are the most vulnerable.It is also notable, that more than the half of the population of the Tatabánya's inhabitants are living in most vulnerable settlements.
