+===== New Features =====
+ENVI-met V4 is completly new in large parts of the model environment and features. After about 6 years of development, there is a huge list of new features introduced in ENVI-met V4. In this feature list below, features only included in the **PROFESSIONAL** version will be marked with  "PROF". Features labled with "Expert" are available only in our laboratory version or additional modules.
-===== Software Concept =====
+For the full model architecture description, a model version feature matrix and details see [[intro:modelconept|ENVI-met Model Architecture]].
-Like always, ENVI-met V4 is free and comes along as a complete model including the full set of features. In addition to the free version (**"ENVI-met Standard"**), there is  a **Professional version** with additional analysis modules and an **Expert Version** with advanced modelling features. The list below summarizes the basic differences between the 3 versions:
-<WRAP   95% center :en>
+==== 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
-<WRAP box left 28%>
+==== General model features ====
- **Standard Version**\\
+  * Calculation of solar access for ground surface and building walls (PROF)
-  * Free
+  * Simple Forcing allows to force temperature and humidity profiles in 24 hourly values onto the model domain
-  * Full ENVI-met Model, no limitations
+  * Water Spray Evaporation (Water fountains, Mist disperser,...) (PROF)
-  * Complete software suite from database editing, over construction to results analysis and visualisation.
-  * New 7 nodes/ 3 layers facade model with prognostic calculation of indoor temperature
-  * Not restrictions is use
-</WRAP>
+==== 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)
+  * Wind and strom risk analysis (Expert)
+  * Water catchment potential (Expert)
+  * TreePass (Expert)
+==== Soil-System ====
-<WRAP box left 28%>
+  * Depth of soil system increased down to -5m
-**Professional Version**\\
+  * Temperature exchange within the soil is full 3D in all layers now allowing to simulate lateral heat flows
-  * Must be licensed
+  * 3D Plant root system allowing to calculate object based water access and extraction data
-  * Additional calculation modules: Solar Access Analysis, Pollutant dispersion chemistry,...)
-  * Single Walls as design elements
-  * Additional model output (building physics)
-  * More and comfortable options for analysing model results

-</WRAP>
-<WRAP box left 28%>
-**Expert Version **\\
-  * Not available for public, only used in our research projects & consulting
-  * Coupling with large scale modells
-  * Further simulation modules (blue technologies, photocatalytic NOx degration,...)
-  * Advanced modelling for landscape architecture (Plant Comfort Analysis PCAS, Water demand simulation,...)
-  * Integrated Building Energy Simulation
-  * New radiation field calculation with IVS
-  * Next generation simulation technologies, some of them future features of V5

-===== Moving over from V3.1 =====
-The documention from V4 is not ready yet. Most of the general itmes of V3.1 can still be used, but there are considerable differences in details. A short overview can be found [[apps:envi4met_changesnutshell|here]].
+==== Buildings ====
+  * Facades and Roofs can consist of up to 3 different layers of material
+  * Full prognostic calculation of wall temperatures (7 node model) (Output only PROF)
+  * Building zone model for estimating building indoor temperature (Output only PROF)
+  * 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.
