Oulu

The pilot building in Oulu, Finland, is one of five student apartment buildings and one building with communal facilities in a housing coorporation. The building was completed in 1985 according to a Finnish industrialized building system developed in the 1970's using prefabricated concrete units for residential buildings, called the "BES system". The building is in need of a complete refurbishment and the student flats are unmodern and lacking in facilities.

 

Retrofit concept

The building renovation includes a comprehensive refurbishment of indoor spaces and a façade renovation with the TES method (http://www.tesenergyfacade.com/)  utilizing timber based, prefabricated elements for the renewal of the building envelope. The refurbishment is aiming for the energy efficiency level of a passive house according to Finnish standards. The building owner will evaluate the results of the demonstration project, with a view towards the modernisation of the other 4 apartment buildings with the same technique.
