Abstract: The Building Information Modeling (BIM) is one of the most advanced methods of representing buildings in terms of modeling level, as the model includes all geometry data and information related to building elements, components, and usage. This is in an addition to the possibility of information exchange and interoperability between different programs, including Building Energy Performance Assessment (BEPA) programs. BEPA programs require the representation model of buildings to include specific sets of necessary geometric and non-geometric data. Consequently, there is a need to evaluate the possibility of using the Building Information Modeling to provide the necessary data (in terms of quality and exchange methods) to be able to perform the energy performance assessment of buildings using BEPA energy simulation and assessment programs. This paper aims to evaluate the role of the BIM in providing the necessary data to assess the energy performance of buildings, especially in the data exchange between BIM and BEPA. The research methodology adopted in this paper includes: (1) determining the most suitable building representation software using the BIM; (2) determining the required and necessary data to appropriately assess the energy performance of buildings and their availability in the generated BIM model; (3) determining the appropriate format for transferring BIM data to BEPA programs; (4) determining the efficiency of the data provided by BIM model to BEPA programs for assessing the energy performance of buildings; and (5) determining the extent to which the efficiency of the exchange of BIM data BEPA programs affects the assessment results.  These are conducted through practical application on a reference-case whose BIM model is developed using the Revit software and exported using GBXML format to some selected BEPA programs, namely Design Builder and IES-VE. The energy performance simulations are conducted using these BEPA programs and their results are compared to evaluate the impact efficiency and impact of exchanged data from BIM on the assessment results on building energy performance. The conclusion of this research includes: (a) the most suitable software for representing the BIM of buildings is Revit; (b) the accuracy of both geometric and non-geometric data represented using BIM programs greatly affect the integrity of the data transferred to BEPA programs; and (c) the appropriate format to transfer the data from BIM to BEPA is through using GBXML data transfer format. However, there is a discrepancy in terms of compatibility between BIM and BEPA programs. It is found that the Design Builder program is more compatible with Revit compared to the IES-VE program in terms of the efficiency of the data transferred and the results of energy performance assessment based on the results obtained from the standard reference-case.v
