Abstract |
With the growing focus on low energy buildings, Building Performance Simulation (BPS) tools have been widely used in the design process. BPS tools can help designers with comparative assessment and rational decision making. 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 simulationists encounter when applying EnergyPlus throughout the design process. The issues are as follows: (1) user’s subjective judgments (assumptions and simplification of the reality), (2) lack of information on simulation inputs, (3) uncertainty in inputs and behaviors, (4) no certification of the simulation model and modelers, (5) tool’s usability. This paper describes how the aforementioned issues hinder efficient use of building simulation tools. In the paper, it is highlighted the importance of the standardized simulation process. |
