Abstract: With the growing focus on low energy buildings, Building Energy Performance Simulation (BEPS) tools have been widely used. However, many issues remain unsolved in terms of transparency, reproducibility, objectivity and usability of such tools. In the paper, the authors report issues and difficulties that a simulationist encounter when applying EnergyPlus to a high-rise office building. The issues are as follows: (1) immature simulation environment (user's subjective judgment, assumptions and simplification of the reality), (2) lack of information on simulation inputs, (3) no certification of the simulation model and modelers, (4) uncertainty in inputs and human behaviors, and (5) ante mortem and postmortem use of the dynamic simulation tool. This paper describes how the aforementioned issues hinder efficient use of building simulation tools. The authors developed a dynamic energy simulation model for a high-rise office building (33 stories above ground and 6 underground levels, a total floor area of 91,898 m²). In the paper, the aforementioned issues are elaborated in detail. Finally, the paper addresses the comparison between the simulation prediction and measured energy use. The tool used in the study is EnergyPlus 6.0. This paper focuses on modeling process and issues, simulation results from the un-calibrated model.
