Renovation of residential building according to Finnish and Lithuanian na-tional building codes

Abstract

The renovation of the residential building in Finland and Lithuania is analysed in this thesis. This is done according to present national building codes. The building with same internal dimensions is analysed in Finnish and Lithuania weather conditions. The IDA ICE program is used to simulate building in Finland conditions and the manual calculations are used to simu-late building performance in Lithuania.

There are three aims of this bachelor thesis. The first one is to find the energy consumptions of the residential building before and after renovation in Finland and Lithuania. The second aim is to find out what changes in the building should be done during the renovation that the building would meet an A energy class according to national building codes in each country after renovation. The third aim is to find out which of the buildings, in Finland or in Lithua-nia, will be more energy efficient according to national build standards after the renovation.
