### 3.2.2. Tabular data and graphical data

As tabular data are understood data entered in editor of Instal-heat&energy program, working only on data tables and some data not entered by the drawing in Instal-therm. Graphical data that are data entered as drawings (storey plan views) in graphical editor of Instal-therm program, which are interpreted in form of tables after loading into Instal-heat&energy, nevertheless the possibility of their modification in tables is locked in big extend – this can be done only in graphical editor.

Above described building data can be qualified as follows:

- partitions definitions are entered only in tabular manner. After their defining it is possible to save file, load it into Instal-therm and assign in graphical editor to partitions creating the storeys plan view the definitions determining their constructions and values of “U”,

- partitions can be both graphical and tabular,

- compartments can be entered both graphically and tabular. Graphical compartment is created on a plan view by drawing the closed structure of graphical partitions. They can be closed on the top and bottom with partitions – floors – both graphical and tabular (added in Instal-heat&energy tables). Tabular compartments are defined only by tabular partitions.

- flats and thermal zones, as conventional groups of compartments are not subject to this qualification. They can be acknowledged as tabular objects, because the assigning of compartments to flats and thermal zones is performed in editor of Instal-heat&energy.

- storeys can be both graphical (they have corresponding sheets of plan views in Instal-therm), and tabular. A graphical storey can contain tabular compartments (added in Instal-heat&energy), but it will cover the data structure and should be applied only in case of lack of other possibilities (for example heat loss to non-heated compartment belonging to adjacent building, non described graphically, the temperature of which is to be determined from the balance). Tabular storey contains of course only tabular compartments. An example is a ceiling, for which we will not create the plan view sheet.

Apart from the character of a storey, the entire information concerning vertical building structure (ordinates and storey heights, floor thickness) are entered only in tabular, unified manner, which is available in both applications.

Moreover, because in Instal-heat&energy program there is a possibility of heaters selection, it is to emphasize, that these heaters have status of tabular heaters. That means, the graphical editor of Instal-therm can not „see” them and they are not taken for hydraulic calculations of the system. It is anticipated, that this option will be changed and heaters preliminary selected in Instal-heat&energy after loading into Instal-therm program will be used for designing of heating installation in a building. Heaters selection in Instal-heat&energy has rather a pictorial character and is used for creating of graphical heaters layout on plan views.
