Poboljšanje energetske efikasnosti objekata visokogradnje reciklabilnim materijalima
Energy Efficiency Improvement in Buildings by Usage of Recycable Materials

Summary/Abstract: The Proces of producting building materials, their transport to the building site, usage in bulding and the usefulness of those buldings are classified as a part of the largest group of energy consumers. According to some new researches, the energy consumption during the object’s exploitation in Serbia are somewhere between 100-250 kWh/m2, but the Standard for new objects that are being constructed in many EU countries is 40KWh/m2, in some even 20 kWh/m2. By the new Law of Construction and Spatial Planning the energy efficiency of buildings is set as the priority in the construction of new buildings. The Rule Book of Energy Efficiency (Official Gazette 61/2011 from 19.08.2011) that is in use since 30.09.2013. obligates designers and contractors to apply the measures so that the existing and new objects could be energy efficient. The existing high-rise buildings, which were built before the regulation for the thermal protection was adopted, can be made more acceptable, more suitable and less demanding from the energy saving point of view, if materials and installations that can be produce by recycling additionally overlay the facade and roof surfaces. In the EU, recycling industry is represented with 58%, and with only 0.3% in Serbia. Results of the research conducted in 2009-2012. pointed out that 30% of designers have no knowledge of recyclable materials which can be applied in construction, and that 82% of designers don’t know if these materials can be used to improve the energy efficiency of buildings.
