Airtightness investigation of residential units building envelope in city of Osijek

This paper describes the airtightness investigation process of existing residential units in the city of Osijek in order to determine their condition and potential for building envelope renovation. Research presented in this paper was the first of this kind carried out in Croatia. The residential units’ airtightness database is obtained in situ at 58 units in the local area. This paper presents average airtightness values for non- renovated residential units in each period of construction and procedure of data processing for forming database needed for neural network learning. Results indicate a trend of significant improvements in airtightness in the periods of recent construction. The results obtained by this research were used for prediction of residential units' airtightness by applying neural networks.
