IDA ICE review
A focused tool for whole-year building energy and indoor-climate simulation.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
IDA ICE is a building-performance simulation application for professionals studying new construction or refurbishments. Its focus is dynamic, whole-year analysis of building energy consumption and indoor climate across multiple zones. Users can model buildings, systems, and controllers, making it relevant to teams that need more than a single-purpose energy estimate. It is aimed at small, mid-market, and enterprise teams, but the central fit is building simulation work rather than general-purpose simulation.
The modeling workflow includes importing common 2D and 3D CAD files and IFC models, then reviewing model feedback graphically in 3D or in tables. Version tracking and rerunning dependent simulation cases can help teams compare iterations as a building model changes. Component models can also be extended with equation-based modeling using Neutral Model Format. These capabilities make IDA ICE a fit where geometry, building systems, and iterative analysis belong in one workflow; teams seeking a narrower calculation tool may find its scope broader than they need.
IDA ICE is available in Standard and Expert editions, with Expert aimed at advanced building simulation professionals and parallel simulation runs listed for that edition. A time-limited Expert trial is offered. Pricing is handled through contact with sales. The application runs on Windows desktop; cloud high-performance computing is described for optimization runs, rather than as the software's deployment model. Teams that need cloud optimization alongside detailed building analysis may find that combination useful, while buyers requiring a cloud-deployed application or a price they can assess without a sales conversation should consider alternatives.
IDA ICE pros and cons

- Simulates whole-year building energy use and indoor climate across multiple zones
- Imports common CAD and IFC models and provides 3D and tabular feedback
- Tracks model versions and reruns dependent simulation cases
- Where it doesn't
- Runs as desktop software on Windows
- Pricing requires contacting sales
- Parallel simulation runs are limited to the Expert edition
