In this context, double-skin facade systems have increasingly been used due to their effectiveness in reducing the heating load, cooling load, and primary energy demand of buildings. In this study, an office building located in the industrial zone in Kocaeli/Gebze was examined, and the effects of nano-technological materials to be added to the building and double-skin facade systems on the energy performance of the building were determined using DesignBuilder and EnergyPlus simulation programs. As a result; with the thermochromic glass and vacuum insulation panels used in the nano scenario, the heating load was reduced by 70% when compared with the base model. In the double skin scenario implemented on the east-west facade, heating load was decreased by almost 25% and cooling and primary energy demand were decreased by nearly 20% as compared to the base model. Whereas, an efficiency of 20% in heating load, 40% in cooling load and almost 30% in primary energy demand was observed in the nano double skin scenario when compared with the base model.eninfo:eu-repo/semantics/closedAccessEnergy savingoffice buildingsustainable developmentintelligent buildingcomputer simulationArticle10.1080/17508975.2024.23100592-s2.0-851842727072656Q225115WOS:001156867000001N/A
