### 2.5.5. Completion of graphical structure of building with data of storey entered in tabular manner

In this chapter will be presented entering of storey, flat and compartment data in tabular manner. It will be non-heated level of cellars.

To do this, please perform following operations:

1. In graphical structure of building select the zero-level of storey clicking the level located on the top of structure tree. After clicking the right mouse button a pop-up menu will appear, from which we can select a command “Add storey in selected area”. Calling this command will cause inserting of new storey under selected (in the tree structure it will appear over selected one). This command we can also open by means of Ins key.

2. Clicking the left mouse button on the new entered level of building structure, just select it and go to storey data edition. Program will automatically assigning field “Name” following number of storey, existing in building structure. It is possible to complete field “Description” entering here comment to the name, for example “Cellar”. Changes concerning the name and description are registered in building structure tree.

3. Following fields concerns the type of storey. Here is only available the type “Ground floor”, which des not correspond with type of selected building level. Because selection of type “Ground floor” will cause assigning to the storey located below the type “Cellar”, it is also necessary to go to the higher storey level and here in edition window, in field “Type” select – “Ground floor”. Such selection causes, that to the storey located below the type “Cellar” will be assigned.

4. Fields concerning vertical building structure are completed with values pre-defined in program. That are: floor ordinate, height of storey in axes, floor thickness and windowsill ordinate. We assume, that these data will comply with project assumptions and we leave them without changes. Field “drr” remains not filled – this is a default width of heater recess. Do not select the field “Relating storey”.

Because the program inserts automatically on each storey a “Default” flat, we will insert here non heated compartment of cellars. Flat data remains unchanged, field “Description” will not be filled and the flat name will not be changed.

If the option of seasonal energy demand for a building has been selected, it is also necessary to complete fields concerning average number of people in a flat, gains from electric devices, gains from cooking and lighting. If there are children in the flat, please select field “Flat with children”.

5. Selecting the level of flat we should click the right mouse button and select command “Add compartment (Ctrl+F7)” The compartment can also be inserted by means of button located between project data and building structure windows.

6. Selecting compartment with number 001 we will open the window for compartment data edition.

7. In field for compartment data edition deselect the field “Heated compartment”, what will mean, that the temperature in non-heated compartment will be calculated on the basis of heat balance.

8. At the beginning it is necessary to complete data in compartment partitions table. In columns of partition table open the names of defined partitions from a pop-up list and complete the partition dimensions.

9. The area of horizontal partition can be completed using the function assigned to key F9. This is very convenient function, switching automatically to Instal-therm program to the function “Inserting (area measurement), where you can switch to adequate working sheet and measure the dimensions of area according to normative required dimensions. After clicking the right mouse button we switch automatically to Instal-heat&energy program

10. Such partition as internal ceiling, which separates storeys in tabular and graphical manner should be inserted switching to the level of graphical storey, located over storey described in tabular manner. Proper “connection” of non-heated and heated storey is necessary for correct calculation of temperature in non heated compartments and heat losses in heated compartments. This stage of data input has been described in chapter 2.5.6.

11. After completing of partitions table continue with completing of other compartment data, located in upper part of edition window. The compartment area in light “As” and the type of compartment ventilation are to be completed.

Because in cellar there is a floor on the ground and internal walls, it is necessary to complete in general data of compartment the field “Ofg-floor perimeter on the ground”, field B – characteristic dimension of floor” is completed automatically on the basis of entered value of floor perimeter on the ground. Because we have not selected in “General data” the detailed calculation method of heat loss to the ground, field “Ssz – external walls thickness” will not be displayed. More information concerning method of thermal calculations in program you can find in APPENDIX B. APPLIED NORMS AND CALCULATION METHODS

If the calculation option of temporary temperature reduction on the basis of data declared in compartment has been selected, it is necessary to select this field and complete the edition fields. More information to this you can find in chapter 4.5.3.1.

Because the non-heated compartment is not ventilated, in field “Ventilation type” select “Others” and declare zero stream of ventilation air in field “Vexh – stream of exhausted air”.

12. Value of field “As” can be completed by means of function called with key F9, measuring the area of compartment according to dimensions in light.

13. In case of selecting the option of calculation of seasonal energy demand it is necessary to assign heated compartments to selected thermal zone. Program will automatically assign the compartments to the location “Beyond zones”. Completion and inserting of thermal zones has been described in chapter 2.8.
