ABSTRACE:In building simulation, as in several other domains, traditional monolithic simulation codes are still in dominance over simulators based on symbolic equations in a general modeling language. IntroducedIn building simulation, as in several other domains, traditional monolithic simulation codes are still in dominance over simulators based on symbolic equations in a general modeling language. Introduced in 1998, IDA Indoor Climate and Energy has become the firrst widely spread thermal building performance simulator based on the new technology. Developing a full-9edged dynamic whole-building simulation program is a formidable endeavor in any setting and since the first beta version in 1997 a number of lessons have been learned. The paper shares some of these experiences concerning general program structure, models, performance, integration, GUI design and issues specilcally linked to equation-based modeling using a variable timestep di=erential-algebraic (DAE) solver. |
