The objective of the toolkit is to calculate the projected energy demand and to identify energy saving potential in comparison to a reference building.
This energy saving potential may be used to apply for loans according to the KfW/NHB program on energy efficient residential buildings.

The Assessment tool itself allows the user to enter the following data:
-    general information on the building project to be assessed
-    key features of the building envelop (geometry, orientation, building materials, etc.)
-    technologies used for space cooling, heating, lighting and hot water

The main features are:
-    easy to handle and intuitive approach to energy demand calculation
-    Kick start your project with the project wizard including sample buildings
-    On time calculations and display of results in an overview area. The impact of every change can be seen immediately.
-    Automatically updates the reference building after every change and calculates the reference energy demand and the energy savings potential.
-    Shows energy savings potential
-    Loan application certificates
