BIM and Sustainable Construction Integration:  An IFC-Based Model

Building Information Modeling (BIM) and sustainability are the two current and emerging movements in the architecture, engineering and construction (AEC) industry. Even though the importance of Green BIM is recognised, there are some barriers to a functional inclusion such as lack of measured sustainable strategies� direct access into BIM. Their integration has a great impact on sustainable construction. Accordingly, this study focuses on setting up a substructure of the Industry Foundation Classes (IFC)�based model for BIM and sustainability integration. The main purpose is to fill the gap of BIM integration with standards of sustainable construction by providing a guideline for the design team to address the sustainable features of the project during the design stage. It provides an integrated platform to work on and facilitates the green documentation generation for getting green building certification. Firstly, the property sets are developed in the IFC structure in order to designate the green properties into BIM projects. This process includes the investigation of major categories and criteria of the Green Building Assessment Systems, determination of the possible categories for IFC schema, creation of the property sets and acquisition of the related data. Following this, the green materials database and library are created to get the sustainable data for the assessment. Next, the BIM model is generated based on the green materials. The assessment tool for the data calculation is presented as the last process of the basis for the integrated model. Finally, the applicability of the model is discussed for future studies.

Bina Enformasyonu Modellemesi (BIM) ve s�rd�r�lebilirlik yap�m sekt�r�nde g�ncel ve geli�mekte olan iki �nemli kavram olarak kar��m�za ��kmaktad�r. S�rd�r�lebilir BIM son y�llarda ortaya ��kan bir gereklilik olmas�na kar��n, i�levsel bir birle�menin �n�nde bir tak�m engeller bulunmaktad�r. Halbuki, s�z konusu iki kavram�n b�t�nle�mesi s�rd�r�lebilir yap�m �zerinde b�y�k bir etkiye ve �neme sahiptir. Bu �al��ma, BIM ve s�rd�r�lebilir yap�m b�t�nle�mesi i�in �nerilen IFC (Industry Foundation Classes)�tabanl� modelin altyap�s�n�n kurgulanmas�na odaklanmaktad�r. Modelin temel amac�, s�rd�r�lebilir yap�ma ili�kin standartlar ile BIM b�t�nle�mesi aras�ndaki mevcut bo�lu�un, s�rd�r�lebilir verilerin BIM arac�l��yla tasar�m s�recine d�hil edilerek doldurulmas�d�r. Ye�il bina sertifikasyonu almak �zere dok�mantasyon olu�umunu kolayla�t�rmak hedeflenmektedir. Bu ba�lamda, �ncelikle IFC veri standard�nda, ye�il bina sertifikasyonu i�in gerekli olan verilerin BIM projelerine aktar�lmas�na olanak sa�layan �zellik setlerinin geli�tirilmesine de�inilmektedir. �zellik setlerinin geli�tirilmesi s�reci, ye�il bina de�erlendirme sistemlerinin temel kategori alanlar�n�n ve kriterlerin incelenmesi, IFC �emas� i�in olas� kategorilerin belirlenmesi, �zellik setlerinin geli�tirilmesi ve ilgili verilerin elde edilmesini kapsamaktad�r. Daha sonra, ye�il malzeme veritaban�na eri�im; bu veritaban�nda yer alan malzemelerin BIM yaz�l�mlar� arac�l��yla olu�turulan projelerde kullan�lmalar�na olanak sa�layan ye�il malzeme k�t�phanesinin yarat�lmas� ve �ablon dosya olu�turulmas� ele al�nmaktad�r. �nerilen model altyap�s�n�n son ad�m� olarak, proje verilerini IFC format�ndan alarak ye�il bina de�erlendirme sisteminin �l��tlerine g�re gerekli hesaplamalar� yapan de�erlendirme arac� sunulmaktad�r. Son olarak, modelin uygulanabilirli�i gelece�e d�n�k �al��malar a��s�ndan irdelenmektedir.
