### 2.6.4. Description of partitions – inserting and identification of partitions

A new created „tabular” compartment does not have initially any cooling partitions. They can be inserted in any sequence clicking the function key F7 or Ins (in partitions table) or by means of icon “Add partition” or the pop-up menu (in building structure tree). New partitions should be described (identified). To perform the identification of partitions it is necessary to complete their data in table. That are: name of partition, type and orientation towards cardinal points of the compass, value of heat transfer coefficient Uo, and addition because of presence of thermal bridges in partition, dimensions or area of partition and indication of environment on the other side of internal partition or inserting of temperature.

Value of heat transfer coefficient Uo can be completed in two ways, depending on method of partition defining. Partitions can be defined in “Partitions definitions” or can be also defined directly in partitions table in „Building structure”.

If the User has defined the partition in „Partition definitions”, he can declare the usage of defined partition in column „Name”, using the key from pop-up list. Such partition can be also selected using the keys Ctrl+Enter or entering its name.

! Because the partition definition is declared under specific name, selecting a name of defined partition its definition is also selected.

If a name of partition defined in “Partitions definition” will be entered (or called), program will find it and complete in partition table of column with value of heat transfer coefficient and partition type. Its area (if not defined previously) and orientation towards cardinal points of the compass are still to be inserted. If the User wants to change here the features of defined partition, he can do this changing its name. It will cause disconnecting from its definition and as a result – loss of possibility of seasonal energy demand calculation. For this reason edition of already defined partitions has to be performed in “Partition definition” without loss of possibility of building seasonal energy demand calculation.

! By changing of partition name defined in “Partition definition” the User can edit it in voluntarily in building structure, but simultaneously he will lose possibility of seasonal energy demand calculation because of lack of sufficient data.

If a partition has not been defined previously, it can be immediate declared in compartment partitions table by completion of its name, type, orientation, value of Uo – coefficient, addition taking into consideration heat leakage bridges in partition and dimensions. Such defined partition can be edited in any way both in compartment view – in compartment table and in window of partition edition “Building structure: Partition”. To switch between these windows use the keys combination Ctrl+G.

Calling of partitions edition window can be done by the User analogous to calling of window for edition of storey, flat and compartment. After selecting a partition in building structure tree a window for partition edition “Building structure: Partition” will appear.

! If partitions have been defined directly in building structure, program will not calculate the seasonal energy demand because of lack of sufficient data concerning partition construction.

For internal partitions, the compartment on the other side of partition can be selected from a list opened in „Ros” column. It is enough to insert an internal partition only once and specify the adjacent compartment only once. Program will automatically assign the internal partition to this compartment and this will be visible for both adjacent compartments. For internal partitions the User can also input the temperature on the other side of partition. Nevertheless declaring of compartments has an important advantage – if the temperature in compartment will change, it is not necessary to correct it in all adjacent compartments, because the program will make it automatically.

It is also possible to declare on the other side of internal partition the type of heated/non-heated compartment. Types of these compartments are entered on the basis of normative guidelines.

Windows” and „doors” in compartment can be entered in two ways. The User can input them as individual partitions, but he has to remember to subtract the area of “window”/”door” from area of wall (in column „AZobl”) or declare the usage of “window”/”door” as a sub-partition. It is also possible to specify the number of windows/doors in specific main partition. In such case the User does not have to assign in compartment table the orientation to windows and external doors and to calculate the area of partitions including windows or (and) doors. The program will automatically calculate its area and the result will be given in column „AZobl”. Orientation of windows/doors towards cardinal points of the compass is analogous to the partition, to which they belong.

”Window”/”door” can be declared as sub-partition in three ways:

- inserting „window”/„door” in a building structure tree, that means, going to partition, on which the User wants to insert „window” or „door” and clicking the icon

- inserting „window”/”door” as a separate partition in compartment table and then clicking the right mouse button and selecting the command „Partition ® Sub-partition”. Then the program will assign “window”/”door” to this partition, which will be placed in table over declared „window”/”door”.

- in partitions table in compartment, using the command „Add sub-partition in cursor’s position” (Ctrl+F7) available in pop-up menu. The User can then enter the name of sub-partition or select in displayed window from windows and doors defined in “Partitions definitions” this one, which he wants to insert as a sub-partition. Selecting this command will cause assigning of windows/doors to partition located in partitions table over inserted sub-partition.

! There is no possibility to insert a sub-partition to partitions being in contact with the ground.

Fields which have to be additionally completed for calculations of seasonal energy demand are described in chapter 4.5.
