1. Installation of the program, Start of the program, and getting used to the graphicaluser interface of Dialux.1.1. Getting the program:Open any browser (Mozilla, Internet Explorer, etc) and open www.dial.deGo to Sprache to change it to English.Figure 1: Website llowed.Go to the dropdown “Dialux” and “Download”:Figure 2: Website DialuxThisisadraftdocumenChoose Dialux 4.12.0.0. for Download (and Dialux ECO 3.1. as well)Figure 3: Website Dialux – Download MenuFollow all steps of the installation.

1.2. Opening the program:Options for opening the tool: Icon / Desktop Start / Dialux / Dialux 4.12. ( NOT: 4.12.

2. Tutorial OutlineThe tutorial is the department’s seminar room. Plans and information are provided inTUWEL.3. Generating a basic room / Geometry entryNOTE: The suggested default room in the above shown dialogue (Fig.8) is a cuboid room 5,4m long, 3,6 m wide, 2,8 m high. The measures can be changed via Input on the keyboard.(Finish with ok).thorizedreproductionorpublicationisallowed. Change the dimensions of the room to 9,50 m length, 6,40 m width and 4 m height, andapply with ok. These are the basic outline measurements for the BPI- seminar-room. Afteryou click on Ok the Menu disappears and is changed to the “General”-Slide. If you did amistake or if you want to change the Geometry once again, please RMC on room1 andchoose Edit Room Geometry and the Geometry Slide appears again.auFigure 10: Edit - DialogueFigure 11: 3D-ViewFigure 12: Rotate CommandThisisadraftdocument.Noun To have a 3d-look at this basic room hit the symbol (3D Standard View).NOTE: A 3D view is opened – note that it is a new slide. You can now easily switch betweenplanar view and 3D view (Fig. 11). There are also other views available (side View, FrontView). To pan around in the 3D-view you can hold the MW and move M around.To rotate the view you can use the rotate Symbol (Fig.12.). In this menu bar you can move,rotate, roam and increase/decrease your view, or switch back to “Arrow”.Figure 13: Registration Cards (3D View)

NOTE: To access the different building parts (Walls, Floor, Ceiling),LMC on Room1 and see in the expanded menu “Workplane”, “Floor”,“Ceiling” and a Folder with the Wall Surfaces. (Figure 13) If you click on Ceiling, Floor, or one of the Walls, the building partis marked red in the 3D View.NOTE: What is meant with workplane? (Figure 14) The workplane isa defined invisible plane in your room which means the surface ofthe tables you will work on. In standard offices the height of thetables is between 70 and 85cms.isallowed. Please choose 73 cm for our example.blication3Figure 15: Workplane tionorpuFigure 14: Tree-StructureNOTE: We need to modify the geometry of our Seminar-room (window niches, glass wall): To do so, RMC in the planar view of the room and choose Edit Room Geometry (Fig. 16).Figure 17: Insert PointFigure 16: Edit Room Geometry

To enter a new point,RMC and choose Insert Point (Fig. 17.). As you can see, in the list of point geometry, you canchange the x and y-values of your points. Please create the room geometry according to thetable of points on next page– the resulting room / point list should look like this (Fig. 18 –21):Figure 20 & 21: Point List & Glas Wall Because you have now a higher number of walls, you should use the possibility ofrenaming walls – for example the glass part of the inside wall should be renamed Glass Wall(that is the part of the wall with the sliding doors). It is also recommendable to name thefront and back wall.

The window niches do notcover the whole height of theroom – so we need to entersomething to cover the upperand lower part.Choose the slider objects andchoose Extrusion Object(Fig.22)ed.

(Figure 45, 46) To get the room in the shape of the drawing, you at first should set the corner points, andthen enter some more points for building the room outlines. (See part 1 of the Tutorial)Figure 46: Adapted GeometryNOTE: You can use the CAD-drawing as a background image inthe 3D view. Usually it is recommended to use the optionRepresent 2D projection of dwg / dxf in 3D view fromthe Property Page.

Setting Parameterspublicationisallowed.NOTE: To determine the important reflectance values for allbuilding parts (ceilings, floors, walls), extend the Room1 –Explorer-Menu, and click on one of the building elements.In the 3d view the marked building part will turn red (unlessyou can not see the building part due to your perspective.You can then rotate the 3D view, and should see themarked building part). In the slide material you can nowdetermine the reflection and some other values about yourbuilding part.NOTE: There is a set of Standard-Materials and alsoStandard-Textures, which are delivered with all thereFigure 51: Settings in Material Editiornecessary values. The textures can be found in the ProjectManager under Colours. Important: If you choose the reflectance first and then a Texture,your reflectance will be overwritten with the reflectance of the texture. It is better to do itthe other way round, first the texture, then the setting of the reflectance, transparency andmirror effect.

This can be done with measurement of Illuminance E in Lux and Luminance Lin cd/m² and the formula: L * Pi / E ρ.The values we use in this Tutorial were measured before, and will be proofed in the lecturesBuilding Diagnostics & Building Diagnostics Laboratory.

Adding LuminairesNOTE:The next Step is the addition of some luminaires.(There is a standard option of calculating the necessary luminaires for certain illuminances,which will dealt with in Part 5b.)First Step is to find the Luminaires for our room.BPI Seminar – Room is lighted by TRILUX Lightings. Please open the TRILUX-Catalogue:Luminaire Selection / Dialux Catalogs / Choos Trilux (If not downloaded until yet - theCatalog needs to be downloaded and installed)Thisisadraftdocument.NSearch for 5051 in the TRILUX Catalog and choose “TRILUX 5051AL-RSX/I/2x49 E” and sayUse

w to enter one or several luminaires, click RMC on Room1 / Insert Luminaires / IndividualLuminaire.Thisisadraftdocument.NThe chosen Luminaire should now be available in the Luminaire Dropdown Menu. A greyframe appears in the Drawing Area, which can be moved to position your luminaire.Choose Insert, and the Luminaire will be inserted.

allowed.You can now choose the inserted luminaire in your project Manager, and change positionalso numerically.ThisisadraftNOTE: The number of Luminaires is shown twice in the project manager: One time under“Luminaires Used”, the other time in the Folder “Luminaires” (under “Individual Luminaires”).Please multiply and position the luminaires as shown in the plan! (Hint: Use the methods“Copy along a line” from First Part of Tutorial!).In the end, your model should look like this:

horNOTE: This was in very short the adding of luminaires to your Dialux-Model. Of course thereare more convenient and advanced methods to add luminaires in a more systematic way.(See 3b).ThisisadraftdocumFirst Calculation: To do a quick first calculation Choose Output / Start Calculation!

Very important is the “Rough Calculation”, whereyou can enter the necessary E (illuminance) in lux. By default itis at 500 lux, which is the standard-value for working places inoffices. Change this value to 750 lux. The necessary luminaireswill be calculated for the working plane (in our case 0,85 m bydefault, which for office standards is rather high) if you click onsuggestion.
