The area data of the building are read from the floor area and
total floor area hatches added to the floor plan drawing of each
floor. Select 
Rooms > 
Calculate Building
Area to add the figures.
If the area figures have not been added, the program will read the areas from the project data card. In the project data card included in the basic software delivery, the area data are located in the Sqm and Total sqm fields on the Building data page.
The U values of building components can be defined in the structure libraries or individually in the opened projects. Indicative U values have been determined for the building components in the structure libraries included in the basic software delivery. If the thickness or materials of a component are edited in the building model, the U value will not be updated automatically; it has to be redefined, if necessary.
Designer and customer data are read from the project data card.
