Building information modelling integrated energy simulation tools in green campus initiatives: Düzce University Campus

Todays, increasing environmental problems have increased concerns about sustainability and created a new agenda for economic development discussions. The solution put forward in this framework has been the concept of "Sustainable Development", which can be summarized as ensuring the transfer of natural resources to future generations without being completely consumed. The definition of sustainable development, which has a wide scope in environmental, economic and social areas, in small city scale university campuses has been the concept of "Green Campus". In this context, the "UI GreenMetric Index", which determines the evaluation measure for green campus applications, was developed by the Universitas Indonesia (UI) in 2010. The main purpose of this study is to create suggestions for making the Duzce University Campus more sustainable within the framework of UI GreenMetric, and to examine the use of BIM data-based energy simulation tools in green campus initiatives. In the study, green campuses with degrees in the UI GreenMetric Index were examined in line with each category for suggestions to be made for Duzce University Campus.In addition, the Duzce University Campus building, which was designed as a smart building, in line with the energy and climate change category in the UI GreenMetric Index, fieldwork was conducted on CO2 emissions, which form the basis of energy consumption, greenhouse gas emissions, renewable energy sources, smart building and green building applications by using BIM data-based Ecodesigner Star energy simulation tool. The field study investigated the effect of the exterior cladding material used in the campus building on CO2 emission. As a result of the study, suggestions were made within the framework of the setting and infrastructure, energy and climate, waste management, water management, transportation and education categories in line with the sample campuses examined. In addition, in the field study conducted for the energy and climate category, it was observed that with the mineral wool insulation exterior cladding, the heating and cooling energy of the building has dropped, and CO2 emissions decreased by 3% with the amount of 17,854 kg/a that's why cost savings of approximately 100,000 TRY/a was achieved as an annual in 2023. For this reason, the study is important in terms of making the Duzce University campus a greener campus within the scope of the UI GreenMetric Index, in addition sets an example for the process of making the campuses more sustainable.
