===Revised road lighting , for Evo 6 and above===
 +
In Evo 6 the section "Road lighting " has been revised.<br />
 +
This section provides support in the planning of lighting installations for roads in Europe:<br />
 +
*EN 13201:2004
 +
*EN 13201:2015
 +
*ROVL 2011

<br />
 +
<br />
 +
<br />
 +
<br />
 +
The planning consists of five steps:<br />
 +
1.Selection of the standard and description of the road profile<br />
 +
2.Configuration of the lighting installation<br />
 +
3.Optimization of the lighting installation<br />
 +
4.Export of all results as a *.csv file (optional)<br />
 +
5.Documentation of the plan<br />
 +
<br />
 +
'''Step  1 > Selection of the standard and description of the road profile:'''<br />
 +
In this step Evo creates a  planning model automatically. This is a road 7 metres wide with 2 lanes and a dry road surface. <br />
 +
A lighting installation is not preselected. The planning standard is set initially to EN 13201:2015. You are in the planning mode in the road tool.<br />

''Selection of the standard''<br />
 +
You can change the planning standard under "Active road" in the drop-down menu "Standard". The standards available are: EN 13201:2004, EN 13201:2015, ROVL 2011. <br />

''Description of the road profile''<br />
 +
To describe the construction parameters of a road, click on the small symbols under "Road profile". Each click on a symbol adds a new element to the profile.<br />
 +
The following profile elements are available to describe a road:<br />
 +
*Carriageway
 +
*Footpath
 +
*Cycle path
 +
*Parking lane
 +
*Grass verge
 +
*Emergency lane
 +
*Central reservation

<br />
 +
<br />
 +
<br />
 +
After creating the  profile with the profile elements you can now change the order of the profile elements . <br />
 +
The arrow indiciates in which the direction the profile element moves. <br />
 +
Each time you make adjustments to the road profile the preview on the lower edge of the screen is updated.<br />

 +
You can add more detailed settings to the profile elements. In the list of profile elements there is always one which is active. <br />
 +
You can change the detailed settings under "Active profile elements". For the carriageway, for example, you can set the road surface and the number of lanes.<br />

<br />
 +
''Selection of the lighting class''<br />
 +
In order to plan a lighting installation you have to indicate the lighting class  for the valuation field. <br />
 +
A lighting class contains a set of photometric parameters together with tolerances to be observed. <br />
 +
The lighting installation should fulfil these requirements. When you add profile elements, Evo automatically creates valuation fields on the profile elements. <br />
 +
The illumination class can be selected under "Valuation field " in the drop-down menu "Lighting class".<br />
 +
[[File:008.png|left|400px|]]

<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
The selection of the valid lighting classes can vary from country to country and should therefore be checked in the national standards.<br />
 +
When starting a project, Evo automatically selects a lighting class. This can be changed in the drop-down menu.
  
=== Construction ===
+
Sometimes Evo may not create valuation fields for some profile elements. This is because in the standards no lighting class is required for certain profile elements (e.g. on a grass verge). <br />
First define the street geometry. DIALux evo always defines a simple street geometry automatically. You can define further street geometries  in order, for example, to take into account the different conditions along the street or road, or duplicate an existing street geometry in order to compare different lighting concepts. All the different variants are displayed in a column of their own in the overview on the right. When you duplicate a street geometry, it may be that the existing luminaires are not copied. In order to duplicate a geometry together with the luminaires, select the function "Duplicate street scheme" under [ Planning - > Duplicate street scheme].
+
Nevertheless by activating "Create new valuation field" you can create a valuation field for such profile elements. <br />
 
+
After doing this, check the lighting class. On the right hand side you can also delete a valuation field.<br />

'''Step 2 > Configuration 0f the lighting installation:'''<br />
 +
''Selecting and importing luminaires''<br />
 +
To configure the lighting installation, change to planning mode in the  luminaire selection tool. Here you will find a luminaire catalogue. <br />
 +
The luminaire catalogue functions in much the same way as the catalogue for indoor and outdoor lighting. <br />
 +
Here you can also make use of the installed/online luminaire catalogues or  LUMsearch. <br />
 +
Via "Import luminaire file" you can insert  common file formats with luminaire data into the catalogue.<br />
 +

<br />
 +
<br />
 +
<br /> 
 +
''Inserting and adjusting a luminaire arrangement''<br />
 +
On the left hand side  you can place a luminaire arrangement  onto the road currently selected. <br />
 +
Evo creates a one-sided luminaire arrangement as a standard for the active luminaire. <br />
 +
Direct results for the layout and the valuation fields are calculated for the road. The preview is updated. <br />
 +
[[File:011.png|left|400px|]]
  
 +
[[File:012.png|400px|]]
 
<br />
 
<br />
 +
Under luminaire layouts you can assign a name to the arrangement and make further detailed settings. <br />
 +
To do this, click on the small triangle on the right next to the luminaire. Here you can change the luminous flux, the power supply or the lamp for the luminaire. <br />
 +

<br />
 
<br />
 +
<br /> 
 +
When planning according to EN 13201:2015, you must add details with regard to the number of operating hours of the luminaire arrangement. <br />
 +
Click again on the small triangle on the right. Here you can enter the time periods and the related dimming values for the luminous flux. <br />
 +
Via "+" you can add a  further time period. This input only appears in the standard EN 13201:2015 because here it is necessary to calculate the energy parameters of a lighting installation.<br />

 +
''Changing the type of layout''<br />
 +
The type of luminaire arrangement can be changed under "Arrangement". To do this, click on the desired button. The following types are available:<br />
 +
*One-sided arrangement  below
 +
*One-sided arrangement above
 +
*Double-sided mirrored arrangement
 +
*Double-sided staggered arrangement
 +
*Arrangement on central reservation
 +
(This is only available if the road profile includes a central reservation) <br />
 +
[[File:015.png|left|400px|]]
 
<br />
 
<br />
 
<br />
 
<br />
==== Active street geometry ====
 
Under "Active street geometry" you can allocate a name to the current street geometry and a description. You can also define the lighting situation.<br />
 
 
<br />
 
<br />
==== Street geometry ====
 
Under "Street geometry" you can define which geometries should be displayed in the overview in order to maintain a clear overview when working on more complex projects. <br />
 
 
<br />
 
<br />
==== Street profile ====

<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br /> 
 +
As a rule Evo always places the luminaires of one group arrangement on a carriageway. If you have not planned a carriageway as a profile element, <br />
 +
Evo uses the first and last profile elements as guidelines. You can select further settings for the whole arrangement: <br />
 +
*a rotation of the pole on its own axis
 +
*the number of luminaires per pole
 +
*either the distance of the pole from the carriageway or the length of the boom
 +
*a longitudinal adjustment of the whole arrangement in relation to the valuation field

<br />
 +
<br />
 +
<br /> 
 +
''Adding  luminaire alternatives''<br />
 +
You have the option of calculating several luminaire alternatives for each luminaire arrangement. <br />
 +
To do this you can add further luminaires as alternatives. In the luminaire catalogue you can make a multiple selection of luminaires <br />
 +
by marking the checkboxes of the desired luminaires. The marked luminaires are then added to the luminaire arrangement by clicking on "Add luminaire as alternative".<br />
 +

<br />
 +
<br />
 +
<br />
 +
<br /> 
 +
After clicking this, the multiple selection in the luminaire catalogue returns to standard settings. <br />
 +
Under luminaire arrangements you now see the list of luminaire alternatives. <br />
 +

<br />
 +
<br />
 +
<br /> 
 +
'''Step 3 > Optimization of the lighting installation:'''<br />
 +
When the road profile and the layout have been defined, optimization can begin. Below the types of arrangement you will find the input options.<br />
 +
[[File:019.png|left|400px|]]
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br /> 
 +
The following parameters in the lighting installation can be optimized:<br />
 +
*Distance between the poles
 +
*Mounting height
 +
*Angle of the booms
 +
*Light overhang
 +
Via the checkbox on the right you can select and deselect the parameters for optimization. <br />
 +
If the parameter is deselected, then the respective value is fixed for all calculations. <br />
 +
If, however, it is selected, a starting value, a target value and an increment can be entered. <br />
 +
Evo then creates in the background a calculation scene for each combination. The calculation of these scenes is via the button "Options".  <br />
 +
The number of scenes to be calculated depends on the active optimization parameters , the resolution of increments and the number of luminaire alternatives. <br />
 +
Evo indicates the number of results to be calculated. When an optimization is running it can be stopped by pressing on the neighbouring button.<br />
 +
[[File:020.png|left|400px|]]
  
Here you can define the cross section of your street. You can use as many elements as you wish such as driving lanes, pavements, cycle paths, parking lanes, grass verges, emergency lanes or central reserves. New elements are also inserted at the top of the list. The elements can be moved using the left mouse button or by using the two arrows in the list. <br />
+
[[File:021.png|400px|]]
 
+
<br />
==== Evaluation fields ====
+
The larger the number of results to be calculated, the longer the calculation will take.<br />
 
+
Evo calculates these scenes parallel. The more processor cores are available for the calculation, the faster the calculation process.<br />
Under [Construction => Evaluation fields] you can change the settings of the evaluation fields. First select the desired street geometry and the section of the street profile whose evaluation field you wish to change.  
+
Per road profile there is a limit of 30995 results. If this figure is exceeded,<br />
 +
luminaire alternatives must be deleted or the settings for optimization parameters must be less precise.
  
Here you can select the lighting category in accordance with CIE 140 / EN 13201 and set further parameters when required.
+
''Display of optimization results''<br />
 
+
If no optimizations are active, you can change into the result mode. Here on the left you will find an entry in the list for each road profile. <br />
The number of calculation points can also be set automatically (pre-set) or a dot matrix can generated.
+
When you select one of the road profiles in the list, the table of results is loaded and displayed on the right. <br />
 
+
Only when an optimization has taken place for the selected road profile, is anything displayed on the screen. <br />
You can also delete and reset the evaluation fields of individual profile sections in order, for example,  to create an evaluation field which spans several sections. To do this you can select several profile sections together.
+
[[File:022.png|left|400px|]]
 
+
Of course, such evaluation fields no longer correspond to the<br />
+
standard  parameters.
+
 
+
In the standard setting there is no evaluation field for the central reserve, for grass verges or parking lanes. These can however be inserted.
+
+
New evaluation fields can only be set <br />
+
after the old ones have been deleted.
+

<br /><br /><br /><br /><br /><br /><br /><br />
+
<br /><br /><br /><br /><br /><br /><br /><br />
+
 
+
=== Planning ===
+
==== Luminaire selection ====
+
Here you can import the desired luminaires and add them to your street geometry in a street lighting arrangement.<br />
+
Of course you can also change the photometric data here.<br />
+
 
+
The luminaire is normally added at the bottom as single-sided arrangement. You can later change the arrangement according to the street geometry. Thus the following arrangements are available: single-sided below or above, two-sided or two-sided staggered. If there is a central reserve in your street geometry then there is also additionally a central reserve arrangement. <br />
+
As well as the type of arrangement for your street lighting arrangement you can also enter here important data for your calculation.<br />
+
 
+
If you wish to optimize according to pole interval, the calculation can be limited by indicating minimum and maximum values and by indicating the increments. You can, for example, calculate a luminaire arrangement with pole intervals from 10.00 to 50.00 meters. By defining the increments you select which pole intervals will be displayed in the results. <br />
+
The same procedure is available for light centre height, boom  angle , and light overhang.<br />
+
 
+
 
+
==== Street schemes ====
+
 
+
Here you can generate either a new street scheme or duplicate your existing street scheme together with the respective luminaire  arrangement. You can allot a new name to your street scheme and a suitable description and set the maintenance factor.
+
 
+
=== Overview ===
+
 
+
Here the street schemes are displayed in a table  with their respective street geometries. You can see the standard boundary values for each valuation field. With the small check box you define whether the boundary value selected should be used and ideally fulfilled during automatic optimisation.
+
 
<br />
 
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
A result per calculation scene always consists of :<br />
 +
*Information about the luminaire
 +
*Optimization parameters valid for the result
 +
*Results of all valuation fields
 +
*Advanced photometric parameters for the luminaire arrangement
  
Please note that, depending on the luminaire used, <br />
+
When you click on any of the results, the line is marked. <br />
on the luminaire arrangement or the street geometry, <br />
+
If you click twice on the result, Evo switches to planning which passes the data from the result to the respective road profile. The preview is updated.<br />
not all the required values will be fulfilled.
+
[[File:023.png|left|400px|]]
 
+
When you have positioned one or more luminaire arrangements the current values or the required parameters will be displayed automatically.
+
 
+
The result displayed is not always the best possible result.<br />
+
Optimisation is required for this.
+
 
+
 
<br />
 
<br />
 +
<br />
 +
<br />
 +
<br />

<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br /> 
 +
'''Step 4 > Exporting all results (optional):'''<br />
 +
As a rule, Evo only stores one result per road. If you have optimized the road profile and would like to store the results, <br />
 +
then you can export theses as a  *.csv file. To do this, select your desired road in the mode "Results" under "Alternative", Evo will then list all the results in a table. <br />
 +
[[File:024.png|left|400px|]]
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br /> 
 +
If no valid results are available, then the table is empty. Via the tick for "Display insufficient results" you can list and then export the non-valid results.<br />
 +
Those results which are listed in the table on the right are always the results which are exported.
  
To attain a better overview in the chart it is possible to cover up the values of individual valuation fields. The values are still taken into consideration but they are simply not displayed. In the lower section of the individual schemes you can start up the optimisation of the schemes. To do this, it is of course necessary that a luminaire arrangement has been put into position. DIALux calculates all possible combinations resulting from your optimisation settings. The results can be viewed in the result mode.
+
Start  export via "Export selected result". A "Save file" dialogue for the *.csv file is then displayed. <br />
 
+
Select a storage location and click on save.<br />
=== Result ===
+
[[File:025.png|left|400px|]]
After optimisation of your street scheme or schemes the results are shown here. <br />
+
<br />
By selecting the scheme on the left hand side you can select the street scheme for which the results should be displayed. <br />
+
<br />
Normally inadequate results will also be displayed which you can hide by ticking under "Properties. Then only valid results are displayed. By clicking on the result overview you select a result which you can export via "Export selected result" and then save. With a double click on a result in the overview you adopt the result in your selected street scheme.
+
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br />
 +
<br /> 
 +
'''Step5 > Documentation of the plans:'''<br />
 +
The final step is documentation of the plans. This takes place in "Documentation" mode. The tree lists all the roads which have been planned in the project . <br />
 +
Per street there is an overview "Planning data". There you will find a summary of the luminaire arrangements and the parameters for the construction of the road.<br />
 +
[[File:026.png|left|400px|]]

<br />
 +
<br />
 +
<br /> 
 +
Below the page "Planning data" you will find detailed documentation of the individual valuation fields and the results. <br />
 +
Per valuation field you will receive an overview page and further pages with isolux lines, <br />
 +
value graphics and tables of results with photometric results on the grid points.<br />

Road lighting

Revised road lighting , for Evo 6 and above

In Evo 6 the section "Road lighting " has been revised.
This section provides support in the planning of lighting installations for roads in Europe:

  • EN 13201:2004
  • EN 13201:2015
  • ROVL 2011

You can start this section by clicking on "Road lighting" on the start screen.

The planning mode consists of three main parts:

  • the input field on the left (1)
  • a list in table form of all road profiles (2)
  • a preview of the selected road on the lower edge of the screen (3)
002.png














The planning consists of five steps:
1.Selection of the standard and description of the road profile
2.Configuration of the lighting installation
3.Optimization of the lighting installation
4.Export of all results as a *.csv file (optional)
5.Documentation of the plan

Step 1 > Selection of the standard and description of the road profile:
In this step Evo creates a planning model automatically. This is a road 7 metres wide with 2 lanes and a dry road surface.
A lighting installation is not preselected. The planning standard is set initially to EN 13201:2015. You are in the planning mode in the road tool.

003.png














Selection of the standard
You can change the planning standard under "Active road" in the drop-down menu "Standard". The standards available are: EN 13201:2004, EN 13201:2015, ROVL 2011.

Description of the road profile
To describe the construction parameters of a road, click on the small symbols under "Road profile". Each click on a symbol adds a new element to the profile.
The following profile elements are available to describe a road:

  • Carriageway
  • Footpath
  • Cycle path
  • Parking lane
  • Grass verge
  • Emergency lane
  • Central reservation

After creating the profile with the profile elements you can now change the order of the profile elements .
The arrow indiciates in which the direction the profile element moves.
Each time you make adjustments to the road profile the preview on the lower edge of the screen is updated.

006.png














You can add more detailed settings to the profile elements. In the list of profile elements there is always one which is active.
You can change the detailed settings under "Active profile elements". For the carriageway, for example, you can set the road surface and the number of lanes.

007.png














Selection of the lighting class
In order to plan a lighting installation you have to indicate the lighting class for the valuation field.
A lighting class contains a set of photometric parameters together with tolerances to be observed.
The lighting installation should fulfil these requirements. When you add profile elements, Evo automatically creates valuation fields on the profile elements.
The illumination class can be selected under "Valuation field " in the drop-down menu "Lighting class".

008.png














The selection of the valid lighting classes can vary from country to country and should therefore be checked in the national standards.
When starting a project, Evo automatically selects a lighting class. This can be changed in the drop-down menu.

Sometimes Evo may not create valuation fields for some profile elements. This is because in the standards no lighting class is required for certain profile elements (e.g. on a grass verge).
Nevertheless by activating "Create new valuation field" you can create a valuation field for such profile elements.
After doing this, check the lighting class. On the right hand side you can also delete a valuation field.

009.png














Step 2 > Configuration 0f the lighting installation:
Selecting and importing luminaires
To configure the lighting installation, change to planning mode in the luminaire selection tool. Here you will find a luminaire catalogue.
The luminaire catalogue functions in much the same way as the catalogue for indoor and outdoor lighting.
Here you can also make use of the installed/online luminaire catalogues or LUMsearch.
Via "Import luminaire file" you can insert common file formats with luminaire data into the catalogue.

010.png














Inserting and adjusting a luminaire arrangement
On the left hand side you can place a luminaire arrangement onto the road currently selected.
Evo creates a one-sided luminaire arrangement as a standard for the active luminaire.
Direct results for the layout and the valuation fields are calculated for the road. The preview is updated.

011.png

012.png
Under luminaire layouts you can assign a name to the arrangement and make further detailed settings.
To do this, click on the small triangle on the right next to the luminaire. Here you can change the luminous flux, the power supply or the lamp for the luminaire.

013.png














When planning according to EN 13201:2015, you must add details with regard to the number of operating hours of the luminaire arrangement.
Click again on the small triangle on the right. Here you can enter the time periods and the related dimming values for the luminous flux.
Via "+" you can add a further time period. This input only appears in the standard EN 13201:2015 because here it is necessary to calculate the energy parameters of a lighting installation.

014.png














Changing the type of layout
The type of luminaire arrangement can be changed under "Arrangement". To do this, click on the desired button. The following types are available:

  • One-sided arrangement below
  • One-sided arrangement above
  • Double-sided mirrored arrangement
  • Double-sided staggered arrangement
  • Arrangement on central reservation

(This is only available if the road profile includes a central reservation)

015.png














As a rule Evo always places the luminaires of one group arrangement on a carriageway. If you have not planned a carriageway as a profile element,
Evo uses the first and last profile elements as guidelines. You can select further settings for the whole arrangement:

  • a rotation of the pole on its own axis
  • the number of luminaires per pole
  • either the distance of the pole from the carriageway or the length of the boom
  • a longitudinal adjustment of the whole arrangement in relation to the valuation field
016.png














Adding luminaire alternatives
You have the option of calculating several luminaire alternatives for each luminaire arrangement.
To do this you can add further luminaires as alternatives. In the luminaire catalogue you can make a multiple selection of luminaires
by marking the checkboxes of the desired luminaires. The marked luminaires are then added to the luminaire arrangement by clicking on "Add luminaire as alternative".

017.png














After clicking this, the multiple selection in the luminaire catalogue returns to standard settings.
Under luminaire arrangements you now see the list of luminaire alternatives.

018.png














Step 3 > Optimization of the lighting installation:
When the road profile and the layout have been defined, optimization can begin. Below the types of arrangement you will find the input options.

019.png














The following parameters in the lighting installation can be optimized:

  • Distance between the poles
  • Mounting height
  • Angle of the booms
  • Light overhang

Via the checkbox on the right you can select and deselect the parameters for optimization.
If the parameter is deselected, then the respective value is fixed for all calculations.
If, however, it is selected, a starting value, a target value and an increment can be entered.
Evo then creates in the background a calculation scene for each combination. The calculation of these scenes is via the button "Options".
The number of scenes to be calculated depends on the active optimization parameters , the resolution of increments and the number of luminaire alternatives.
Evo indicates the number of results to be calculated. When an optimization is running it can be stopped by pressing on the neighbouring button.

020.png

021.png

The larger the number of results to be calculated, the longer the calculation will take.
Evo calculates these scenes parallel. The more processor cores are available for the calculation, the faster the calculation process.
Per road profile there is a limit of 30995 results. If this figure is exceeded,
luminaire alternatives must be deleted or the settings for optimization parameters must be less precise.

Display of optimization results
If no optimizations are active, you can change into the result mode. Here on the left you will find an entry in the list for each road profile.
When you select one of the road profiles in the list, the table of results is loaded and displayed on the right.
Only when an optimization has taken place for the selected road profile, is anything displayed on the screen.

022.png














A result per calculation scene always consists of :

  • Information about the luminaire
  • Optimization parameters valid for the result
  • Results of all valuation fields
  • Advanced photometric parameters for the luminaire arrangement

When you click on any of the results, the line is marked.
If you click twice on the result, Evo switches to planning which passes the data from the result to the respective road profile. The preview is updated.

023.png














Step 4 > Exporting all results (optional):
As a rule, Evo only stores one result per road. If you have optimized the road profile and would like to store the results,
then you can export theses as a *.csv file. To do this, select your desired road in the mode "Results" under "Alternative", Evo will then list all the results in a table.

024.png














If no valid results are available, then the table is empty. Via the tick for "Display insufficient results" you can list and then export the non-valid results.
Those results which are listed in the table on the right are always the results which are exported.

Start export via "Export selected result". A "Save file" dialogue for the *.csv file is then displayed.
Select a storage location and click on save.

025.png














Step5 > Documentation of the plans:
The final step is documentation of the plans. This takes place in "Documentation" mode. The tree lists all the roads which have been planned in the project .
Per street there is an overview "Planning data". There you will find a summary of the luminaire arrangements and the parameters for the construction of the road.

026.png














Below the page "Planning data" you will find detailed documentation of the individual valuation fields and the results.
Per valuation field you will receive an overview page and further pages with isolux lines,
value graphics and tables of results with photometric results on the grid points.
