After about 6 years of developement, there is a huge list of new features introduced in ENVI-met V4.

In this feature list below, features only included in the Professional or Expert version will be marked with “Prof” or “Expert”.

For the full model architecture description, a model version feature matrix and details see ENVI-met Model Architecture.

• Full 3D model geometry allowing to design even complicated environments
• Thin single walls as elements (Prof)
• Wall and roof materials can be assigned individually to each wall or roof segment

• Calculation of solar access for ground surface and builing walls (Prof)
• Simple Forcing allows to force temperature and humidity profils in 24 hourly values onto the model domain

• Improoved calculation modules for all variables
• Simple forcing of air temperature and humidity in 2 m level (24 h cycle)
• Full forcing of all variables including wind speed and direction for coupling with larger scale models (Expert)

• 3D Vegetation, interpreting the tree/bush/… as an integrated organism
• 3D Root Model
• Advanded water stress modelling
• Plant stress and health analysis (Expert)
• TreePass (Expert)

• Depth of soil system increased down to -5m
• Temperature exchange within the soil is full 3D in all layers now.
• 3D Plant root system allowing to calculate object based water access and extraction data

• Facades and Roofs can consist of up to 3 different layers of material
• Full prognostic calculation of wall temperatures (7 node model)
• Building zone model for estimating building indoor temperature (Output only Expert)
• Detailed dynamic data of microclimate along the building envelope (Prof)

The software environment was completely redesigned to support all of the new features, especially those in 3D. All input can now be edited visually, including the new database system. For details, refer to the ENVI-met Applications Homepage
