### 5.3.2. Appending additional components to the construction

Rooms formed by inserting and joining walls in accordance with the description above or inserted by means of the “Room” component are of fundamental importance to the process of designing and calculating a radiant heating system. Other structural components, such as windows, doors, and horizontal partitions: floor and ceiling, are complementary. These components are indispensable for calculating heat losses. They can be inserted as graphical components in the editor or specified in tables in Instal-heat&energy.

Openings in walls are graphical components and have no effect on the properties of rooms and on the system being designed. However, placing these components on the drawing is often important for the clarity of the drawing

The properties of complementary components are similar to those of the fittings in the graphical editor – they cannot stand alone. They can only be placed on the wall (window, door, opening) or within room area (horizontal partitions: floor, ceiling) to which they are assigned in terms of the drawing, and sometimes also in terms of data fields in the data table.

¨ To place a window, door or an opening in an existing wall:

1. Click the appropriate button on the „Components” toolbar – for an opening in wall, for a window or for a door. The component inserting mode is enabled.

2. Position the mouse pointer on the wall axis at the point where the centre of the component (e.g. window) is to be located:

3. Press the left mouse button. The component is inserted at the indicated point of the wall:

4. If the mouse pointer is not exactly on the axis of the wall, the component is not inserted and an audible warning signal is sounded and an appropriate message is displayed in the status bar.

5. After inserting a wall with a component, a window for instance, these components are marked. Thus you can specify the window data at once. The width of the window is taken from the building structure data or a default value is adopted. To change the width and depth of the window enter the desired values into appropriate fields in the data table (window data are displayed below the wall data).

6. If the window is not oriented properly, drag the small square with an arrow , displayed near the window.

7. In the case of door, by dragging the small square with an arrow you can change both the side to which the door opens (outwards or inwards) and the direction of door opening (right or left):

8. To move a window, door or an opening, position the mouse pointer on the axis of the wall occupied by that component, press and hold the left mouse button and drag the component along the wall. You cannot move a window from one wall to another this way!

¨ To place a horizontal partition of the floor or ceiling type in an existing wall:

1. Click the appropriate button on the „Components” toolbar – for floor or for ceiling. The component inserting mode is enabled.

2. Position the mouse pointer within the room area:

3. Press the left mouse button. The selected component is inserted in the room area within room axes and adapts it to the shape of the room below or above.

4. The inserted partition is marked. Thus you can specify the window data at once.

5. To insert several partitions of the floor or ceiling type into one room, repeat the operations described above.

! If under the edited room there is (on the plan view of the storey below) more than one room, the horizontal partition – floor will only cover the part common to both rooms. Therefore, several such partitions have to be inserted. The same applies to rooms above.
