Energy Analysis alternatives comparison
| Tool | Verdict | Composite | Price signal | Agent access | Key formats |
|---|---|---|---|---|---|
| OpenStudio C1 5/5 reflects the free license, C2 4/5 reflects CLI plus Python, Ruby, C++, and C# bindings, and C4 5/5 reflects OSM, IDF, gbXML, IFC, and epJSON workflows. Integrations include EnergyPlus, Revit, Radiance, URBANopt, and Rhino/Grasshopper via Honeybee; firm-size fit is solo to small-team. | Worth it | 4.4 | Free tier | CLI / API | OSM, IDF, gbXML, IFC |
| C.Scale A genuine free tier plus a documented REST API and native embedding inside Autodesk Forma make it an easy, low-risk way to add embodied-carbon assessment to early design, though the free tier caps out at 3 projects and paid pricing is quote-based. | Worth it | 4.4 | Free tier + from $0 + quote | API | |
| Ladybug Tools C1 4/5 reflects the freemium model, C2 4/5 reflects the CLI plus Python and Pollination SDK surfaces, and C4 5/5 reflects HBJSON, gbXML, IDF, epJSON, .rad, IFC, and GEM workflows. Integrations include Rhino, Grasshopper, Revit, EnergyPlus, OpenStudio, IES VE, Radiance, and URBANopt; firm-size fit is solo to small-team. | Worth it | 4.0 | Free tier | CLI / API | HBJSON, gbXML, IDF, epJSON |
| EnergyPlus C1 5/5 reflects the free license, C2 4/5 reflects CLI plus the Python and C APIs, and C4 5/5 reflects IDF, epJSON, gbXML, CSV, SQL, ESO, and ERR workflows. Integrations include OpenStudio, DesignBuilder, Ladybug/Honeybee, ClimateStudio, IES VE, eQUEST, and Simergy; firm-size fit is solo to small-team. | Worth it | 4.0 | Free tier | CLI / API | IDF, epJSON, gbXML, CSV |
| Pollination C2 4/5 reflects the documented REST API, Python SDK, and CLI, C5 5/5 reflects the Rhino, Grasshopper, Revit, EnergyPlus, Radiance, and OpenStudio ecosystem, and C4 3/5 reflects HBJSON, gbXML, IFC, IDF, and OSM coverage. | Worth it | 4.0 | Free tier + from $1,375 | CLI / API | HBJSON, gbXML, IFC, IDF |
| IES VE C2 3/5 reflects the VE and Apache Cloud API surface plus Python automation, and C5 4/5 reflects Revit, SketchUp, Pollination, and Rhino integrations. RF1 marks quote-only pricing, RF3 marks the proprietary GEM model format, and file exchange includes gbXML, IFC, and MIT. | Solid | 3.8 | Quote-only | API | GEM, gbXML, IFC, MIT |
| cove.tool A documented REST API and native Revit/Rhino-Grasshopper/SketchUp plugins plus open gbXML interchange make it a strong early-design energy/daylight/carbon analysis layer, but pricing is quote-only across every source checked. | Solid | 3.6 | Quote-only | API | GBXML |
| SimScale Cloud CFD/simulation with data center cooling specialty: ASHRAE 90.4 + EN 50600 compliance workflows. Freemium model: Community (free, 10 sims) + Professional/Teams/Enterprise (quote). Browser-based, no install. C1 3/5 (freemium entry, paid tiers quote-based); C2 3/5 (Simulation API in enterprise; Python bindings for automation); C3 4/5 (instant cloud access, tutorials, community); C4 4/5 (standard physics outputs, multi-format export); C5 4/5 (Onshape, Autodesk CFD/Inventor, RhinoCAM, CFturbo, SOLIDWORKS integrations; 900k+ users). Distinct from single-purpose DC CFD (CoolSim) by multi-physics scope and BIM/CAD integration. | Solid | 3.6 | Free tier + from $0 | None | STEP, IGES, STL |
| DesignBuilder C2 3/5 reflects Python scripting, a C# API, and EnergyPlus EMS runtime scripting, while C4 4/5 reflects gbXML, IDF, and epJSON workflows. Pricing is published as a subscription, integrations include Revit, ArchiCAD, Grasshopper, MicroStation, and EnergyPlus, and firm-size fit is solo to small-team. | Solid | 3.4 | Subscription | None | gbXML, IDF, epJSON |
| EcoStruxure IT Design CFD C1 4/5 reflects published annual pricing at $5,380, and C3 4/5 reflects browser-based deployment for small-team to growing data-center workflows. C2 2/5 reflects no confirmed Design CFD API, and C4 3/5 reflects PDF export rather than broad model exchange. | Solid | 3.2 | from $5,380 | API | |
| Sefaira C1 4/5 reflects published tiered subscription pricing and a trial, while RF2 and C2 1/5 reflect a GUI plugin workflow with no API, CLI, or scripting surface.

Direct competitor to ETAP (already in catalog). | Situational | 2.6 | Quote-only | None | None listed |
| Cadence Reality DC Design The energy placement is data-center CFD and carbon or thermal analysis. C4 3/5 reflects CSV export and partial BIM import, and RF1 and RF2 keep C1 2/5 and C2 2/5 because pricing is contact-for-quote and no public REST API or SDK is documented, even though Pro-tier automation and an NVIDIA Omniverse extension are documented. | Situational | 2.4 | Quote-only | API | CSV, BIM |
