Overview

For each project you add a set of rooms.

This section describes how to create and manage a room:

Create new room

When you have opened an empty project, a new room will be automatically added.

In this case, you just have to fill in the information and click save.

Creating a new room

To create a new room, click the "New Room" button from the top button bar:

The input fields on the right side will now be cleared and ready for input.

Description

The "User" field will be used for access restrictions in a multi-user setup, and also shown in reports.

You can also add extra information, which will be included in reports.

"Category" is filtered by the "Energy calculation" setting for the project.

"Path" contains the location of the DWG file (if applicable).

It is also possible to set which floor a room is located on.

"Indoor"/"Outdoor" changes whether ceiling and walls are included in room calculation.

Room geometry

First you must select the basic room shape. This determines the amount of input fields on the right.

Next, input the room size in meters. The average mounting height will be used when inserting luminaires.

The total room area (m²) will be calculated on the fly, and the preview will continuously show the room shape.

Note: if you are importing room data from CAD, these fields will be filled in automatically.

Reflection and Luminous data

Next, you must setup the surface reflection values. Standard reflection values can be selected from the drop-down box.

The luminous data section describes the desired lighting characteristics for the room.

The maintenance factor can be set up with an easy or advanced interface.

Calculation plane heights (separate for normal and emergency modes) can be configured here.

Read about setting up border zones in the [link] chapter.

Note: the button "EN 12464" will not be active before the luminaires have been added to the room.

Luminaires

To add luminaires, click

. This will bring up the luminaire search dialogue.

Click the button

to open your favourites directly.

When a luminaire type has been added, its row will be automatically selected.

You can now enter the desired number of luminaires (No), or click the

button to perform an automatic calculation

Position labeling

The position labeling window will only be visible if the project is configured with a labeling system. See the Position Labeling topic for details.

Incompatible Room

A room is incompatible when there is insufficient data to do operations like copy or create report. There are many ways this can occur. F.ex. a room missing luminaire positioning is missing vital information for Luminaire reports.

The Room status

The room has the following 3 statuses:

- Indicates that the room is incompatible and cannot be copied or used in a report.

- The room has compatible data and can be copied or used in a report, but has no calculations.

- The room has compatible data and is calculated. This room can be copied or used in a report.

These statuses can be observed in the room list:

In the project report you can differentiate the room status by looking at the room name:

Notice the star behind almost each name. Two stars indicates an incompatible room. One star indicates a room without an calculation, but is compatible. A room without a star is a compatible room with calculations.

If your selection contains a room with two stars, attempting to run a report will generate this warning:

Making a room compatible

Incompatible rooms are in many cases just a room not yet finished. Make sure that fields like Length, Width and Height have values.

The room also needs luminaire data. Choose a luminaire and go to luminaire position 3D. You do not have to calculate the room, only place the luminaire in the room.

If you change something in the room window, this must be updated in the luminaire position 3D. So if you change Border zone, luminaire type or other important luminaire data, go to the Luminaire Positioning 3D and save these changes.

Simple maintenance factor

Selecting maintenance factor

The easiest way to setup maintenance factor for the room, is to simply choose one from the drop-down box or type it in directly:

This maintenance factor will be global for the entire room, i.e all luminaires in this room will use this factor.

Changing from advanced to easy maintenance factor

If you have configured a room using the advanced maintenance factor but wish to go back to the easy setup, you must uncheck the EN 12464 checkbox:

Advanced maintenance factor

Using earlier settings

If the room doesn't have any previous maintenance factor settings, the following question will pop-up:

If you choose Yes the application will search for similar rooms and luminaries and select these settings automatically.

Room similarity is based on the room index RI, and luminaries must be of the exact same type if settings are to be copied.

Setting up maintenance factor

If no similar settings were encountered, the following screen will be shown with all fields blank:

Room

First, select the room Environment, which means how clean the room is. The options are Dirty, Normal and Clean.

The Maintenance Interval describes how often the room is cleaned (floor, walls and ceiling).

Ambient conditions can be determined by the type of lighting used in the room.

• Downlight luminaries will give a more direct light distribution.

• Uplight luminaries will give an indirect light distribution.

Finally, select the room Category. You can select from a list of building types and their associated room types. If category has already been set in Energy evaluation, it cannot be changed from here.

When all the room settings has been selected, a Room Surface Maintenance Factor (RSMF) will be shown to the right.

Luminaire

For each luminaire you must select its type and maintenance interval.

The Luminaire Type describes how the luminaire is formed. This information is important to determine how the light deteriorates over time.

The Maintenance interval will be set to the room maintenance interval (configured above), but can be modified per luminaire.

This setting describes how often the luminaires of this type will be cleaned.

Light source

For each luminaire (and their light sources), the lamp type, replacement method and replacement interval must be configured.

The Lamp type will be automatically read from the database, but can be changed if so desired.

The Replacement field has two options; Group or Individual. Individual replacement means that light sources will be replaced whenever needed.

The Replacement interval describes how often the light sources will be replaced.

Resulting values

When all settings have been configured, a set of factors (LLMF, LSF, LMF) will be shown in the appropriate grids.

The resulting maintenance factor (MF) for each luminaire will be shown in the middle grid:

Click OK to go save and exit to the room dialogue. The resulting MF for each luminaire will be shown in the luminaire grid:

To save these settings, click OK or the save button. If you have earlier calculation results for this room, they will be deleted.

Calculate multiple rooms

You have the option to calculate a selection of rooms, directly from the room. This is very useful in situations where you have a large collections of rooms with minimal changes that needs calculations.

Select the rooms you want in the list and activate the "Calculate"-button. Now you will be presented with the same options you would if you used the "Luminaire Positioning 3D" button.

The options you select here will be automated for all rooms you are calculating. When you have chosen the options for your calculation, you can go ahead and calculate.

The white console will output a log of any rooms with complications. If a room cannot be calculated for any reason, the log will display the error and the calculation will continue to the next room.

The calculation will go back and forth between the room and the editor, and the loading bar will display the progress the calculation has made.
