PREFABRICATED TIMBER PANELS APPLICATION POSSIBILITIES FOR THE ENERGY REFURBISHMENT OF RESIDENTIAL BUILDINGS ENVELOPE IN BOSNIA-HERZEGOVINA AND SLOVENIA

System of prefabricated modules installed on the existing building envelope is one alternative solution for deep energy refurbishment of buildings in the European Union. It allows thermal upgrade installation of new parts in the HVAC system. Moreover, some elements of the envelope can be made of renewable materials. This research compares the residential building stock and identifies potential types of buildings for energy refurbishment in Bosnia and Herzegovina and Slovenia. It presents refurbishment possibilities of existing residential building stock in both countries with prefabricated timber panels. It also presents potential obstacles to the wider application of this refurbishment solution.
