ENVI-met 4. A holistic Microclimate Modelling System
Welcome to ENVI-met, the holistic microclimate modelling system.
ENVI-met 4 is the next generation of our high-resolution microclimate modelling system. After more than 6 years of development since the last release, ENVI-met 4 offers a huge set innovative and state-of-the-art approaches and new simulation modules to understand and quantify the interactions between your local environment and the outdoor microclimate.

ENVI-met is a three-dimensional microclimate model designed to simulate the surface-plant-air interactions in urban environment with a typical resolution down to 0.5 m in space and 1- 5 sec in time. Typical areas of application are Architecture, Landscape Architecture, Building Design or Environmental Planing, just to name a few.
ENVI-met is a prognostic model based on the fundamental laws of fluid dynamics and thermodynamics. The model includes the simulation of:
- Flow around and between buildings
- Exchange processes at the ground surface and at building walls
- Building physics
- Impact of vegetation of the local microclimate
- Pollutant dispersion
With ENVI-met, you will be able to simulate the urban microclimate as an interactive system consisting of dozens of dynamic subsystems ranging from atmospheric dynamics, over soil physics, vegetation response down to building indoor climate. All systems, from soil hydrology to building energy simulation are calculated in one big model e.g. an urban quarter, allowing them to interact and adopt like a real environmental system does. The ENVI-met system will provide high-resolution data for any of these components, being it one building out of 500 or one tree within 1.500 trees.
For a first look into the ENVI-met concept, jump to The ENVI-met model architecture.
