IDA Indoor Climate and Energy
IDA Indoor Climate and Energy (IDA ICE) is a new type of simulation tool that takes building performance to another level. It accurately models the building, its systems, and controllers – ensuring the lowest possible energy consumption and the best possible occupant comfort.
IDA ICE is an innovative and trusted whole-year detailed and dynamic multi-zone simulation application for study of thermal indoor climate as well as the energy consumption of the entire building. The physical models of IDA ICE reflect the latest research and best models available, and the computed results compare well with measured data. While serving a global market, IDA ICE is adapted to local languages and requirements (climate data, standards, special systems, special reports, product and material data).
The IDA ICE user interface is designed to make it easy to build and simulate both simple and advanced cases, while still offering the advanced user full flexibility. You can refine your model in steps, while always providing both 3D graphical and tabular feedback. You work in a single program and may jump back and forth between tasks.
Productivity tools like BIM import and version handling make you more efficient.
IDA ICE imports all common 2D and 3D CAD files, and it supports IFC models generated by, e.g. ArchiCAD, Revit, AutoCAD Architecture, and MagiCAD. The version handling system keeps track on model changes and automatically rerun all cases that depend on a change. The differences are stored and results are effectively compared.
Equation based modelling, using the Modelica-like Neutral Model Format (NMF), makes it straight-forward to quickly expand the software with new modelling capabilities, either by our in-house development team or by the experienced user. The newly created component models can also easily be shared with other IDA ICE users.
IDA ICE is not a black box, which means that we do not ask you to trust our secret model.
Every underlying equation can be browsed, and every variable can be logged. For a single zone, this means that about a thousand temperatures, heat fluxes, CO2-levels, control signals and other variables can be inspected by the critical user.
An advantage of using a modern general-purpose variable time step solver, rather than the hand-coded component subroutines of all other available whole-building simulators, is that it automatically adapts to the nature of the problem. By choice of tolerance parameters, you can effectively eliminate numerical errors and see how the equations truly behave – even with a time resolution of seconds if needed.
