ENERGY RENOVATION OF RESIDENTIAL BUILDING ENVELOPE USING ORGANIC MATERIALS FOR THE LEVEL OF COST-OPTIMAL IMPROVEMENT/ UPGRADE IN BOSNIA-HERZEGOVINA AND SERBIA
Towards building renovation strategies, the research is led by a very deep renovation of residential buildings, which would reduce the energy need for heating below 40 kWh/m2 or create energy savings 60%. The renovation of the building envelope, guided by organic materials (such as wood), which is in the one of key principles in the New Renovation Wave Strategy of the European Union from October 2020, is presented in the paper. Energy saving made by renovating building envelopes using wooden modular systems, are shown through characteristic building on which their application is adequate. Case study from Bosnia and Herzegovina indicate possible energy savings of 81% for residential type Multi-family houses – MFH from period 1961-1970.
