IDA Indoor Climate and Energy (IDA ICE) is a whole year detailed and dynamic multi-zone simulation application for the study of indoor climate as well as energy. The physical models of IDA ICE reflect the latest research and best models available, and 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, and product and material data). The IDA ICE user interface is designed to make it easy to build and simulate both simple and advanced cases, and the real-time 3D environment, in combination with comprehensive tables, provides optimal feedback. A simple procedure for calculating and reporting cooling, heating, air demand, and energy, together with a built-in version handling system, makes it easy and efficient to compare different systems and results. There is also the Early Stage Building Optimization (ESBO) user interface which makes it possible for users to experiment with variations in both buildings and systems at an early stage with an absolute minimum of user input. A full range of component models for renewable energy studies is available, with boreholes, stratified tanks, heat pumps, solar collectors, CHP, PV, wind turbines, etc. The standard edition of IDA ICE can be enhanced with various extension packages, each for the more advanced user or for less common studies:
The BIM Import extension allows users to import 3D CAD buildings directly into IDA ICE using the open and neutral IFC format.
The ASHRAE 90.1-extension helps users to follow the Building Performance Rating Method in Appendix G of ASHRAE 90.1-2007, which is used in Green Building Programs like LEED and BREEAM.
Slab Cooling and Heating
The Slab Cooling and Heating extension allows users to handle embedded heating and cooling systems (TABS), both electrical and water based.
Enhanced Window Models
The Enhanced Window Models extension allows users to simulate ventilated double skin facades and other complex glass facades in accordance with ISO 15099.
Ice Rinks and Pools
The Ice Rinks and Pools extension allows users to simulate needed cooling and heating of water in a swimming pool in order to reach and maintain desired setpoint temperatures; for ice formation, the phase change process is evaluated along with the heat needed (in the ground below the ice sheet) to prevent frost propagation.
