ABSTRACT

Building Information Modeling (BIM) and Energy Simulation have both become increasingly important tools in the building sector. The potential exists to achieve a synergistic relationship between BIM and energy simulation software programs by leveraging information stored within BIM models to inform energy models to save time and improve a design's performance. This study seeks to understand the perceptions of green design stakeholders with regard to the value of BIM-based energy simulation as well as associated barriers and benefits. To do so, an e-survey was used to collect data. Data analysis consisted of descriptive statistics, Cronbach's Alpha coefficients, Spearman correlations, and Mann-Whitney U tests. Results suggest that little to no correlation exists between green design stakeholders' perceptions regarding the value of using information from BIMs to inform energy simulation, and their engagement level with BIM and/or energy simulation. While this study has been limited by its sample size and location of participants, the results help identify different user groups' perceptions and receptiveness to using BIM-based energy simulation tools, which are advancing and transforming the AEC industry. Studies, such as this, emphasize the need for further research on understanding the modeling processes related to energy simulation and BIM models.
