Yes and no. Let’s clarify.
ENVI-met is not open-source software, nor is it completely free for commercial use. However, the developers offer a free tier known as the ENVI-met Entry License (formerly called the "Free Demo Version"). This allows non-commercial users—especially students and researchers—to access most core features at zero cost.
Developed by ENVI-met GmbH, this software is widely regarded as the gold standard for micro-scale environmental modeling. It allows users to:
Typical applications include urban design, building climatology, environmental impact assessments, and academic research. envi-met software free download
ENVI-met is a leading 3D microclimate modeling software used primarily for simulating surface-plant-air interactions in urban environments. It is widely applied in urban climatology, environmental planning, architecture, and climate-responsive design. Developed by ENVI-met GmbH (Germany), the software models parameters such as wind flow, temperature, humidity, radiation fluxes, and pollutant dispersion at high spatial (0.5–10 m) and temporal (1–10 s) resolutions.

ENVI‑Met is a science‑based, 3D microclimate model designed to simulate surface‑plant‑air interactions in urban environments. It’s widely used by: Yes and no
The official free version (historically called “Free Edition” or “Lite”) typically includes:
| Feature | Free Version | Commercial Version | |--------|--------------|--------------------| | Model domain size | ≤ 50x50x20 grids | Unlimited (≥ 250x250) | | Simulation duration | ≤ 24 hours | Unlimited | | Nesting grids | Not available | Available | | Full output variables | Limited (e.g., no turbulence, no full radiation outputs) | All variables | | 3D plants and advanced materials | Basic library | Full database + custom | | Pollutant dispersion (CO₂, PM, NOx) | No | Yes | | Python interface (ENVI-met Py) | Limited | Full access | | Technical support | Community forum only | Priority email support |
Yes – the ENVI‑Met Demo (formerly “Student”) version is completely free. It is not a trial; it’s a limited but fully functional version for learning, research, and small projects. ENVI-met is a leading 3D microclimate modeling software
However, the full commercial ENVI‑Met (Unlimited or Enterprise) requires a paid license. No legal free download exists for those editions.
ENVI-met GmbH has shown commitment to education by maintaining the Entry License. However, as features multiply (e.g., pollen dispersion, facade greening, urban PV modeling), the free version may become more restricted. For now, early 2026 trends indicate:
