-====== What's new in ENVI-met V4 ======
-After about 6 years of developement, there is a huge list of new features introduced in ENVI-met V4.
-===== New Features and changes =====
-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 [[intro:modelconept|ENVI-met Model Architecture]].
-==== Model Geometry/ Model Features ====
-  * 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
-==== General model features ====
-  * 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
-==== Atmosphere ====
-  * Improved calculation modules for all variables
-  * Simple forcing of air temperature and humidity in 2m level (24 h cycle)
-  * Full forcing of all variables including wind speed and direction for coupling with larger scale models (Expert)
-==== Vegetation ====
-  * 3D Vegetation, interpreting the tree/bush/... as an integrated 3D organism
-  * 3D Root Model interacting with soi water model
-  * Advanded water stress modelling
-  * Plant stress and health analysis (Expert)
-  * TreePass (Expert)
-==== Soil-System ====
-  * Depth of soil system increased down to -5m
-  * Temperature exchange within the soil is full 3D in all layers now allowing to simulate lateral heat flows
-  * 3D Plant root system allowing to calculate object based water access and extraction data
-==== Buildings ====
-  * 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)
-==== Biometerology ====
-==== New Software Environment ====
-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.
