CYPELUX

Introduction

CYPELUX is a program developed for the lighting design of normal and emergency lighting systems as well as daylight illumination and evaluates them in accordance with the codes from different countries and regions or using checks with customised parameters.

In addition, justification of daylighting requirements for LEED v4 certification can be provided.

The app can import the necessary information extracted from other Open BIM tools, so that the architectural models can be used as the geometrical basis for the development of the lighting system.

The program also includes Radiance software developed by the Lawrence Berkeley National Laboratory.

Data entry

Free modelling / with templates

• Designing the system by entering it freely in CYPELUX.
• Defining system in CYPELUX based on DXF/DWG, DWF templates or images (.jpeg, .jpg, .bmp, .wmf).

Importing BIM models

If the CYPELUX job is linked to a BIM project on the BIMserver.center platform, the following actions can be carried out:

• Importing the model with the building geometry. This allows users to generate the building’s floor plan and to enter the system’s elements based on this geometry. Users can also import the zones based on the spaces read from the BIM model and the layout of the glazed openings. The following options are available:
  • Importing models designed in IFC Builder.
  • Importing models designed in CYPE Architecture*.
  • Importing models in IFC format with IFC Uploader* (generated by CAD/BIM programs such as Allplan, Archicad and others).
  • Importing models designed in Autodesk Revit with the Open BIM - Revit Plugin.
    *Only if daylight does not need to be calculated.
  • If IFC Builder or CYPE Architecture generates the architectural model, users can also import the DXF or DWG templates contained in that model, or those generated by the same program (from the building elements entered) when a model is exported to the BIM project.

Data output

• Exporting reports to HTML, DOCX, PDF, RTF and TXT formats.
• Exporting drawings to DXF, DWG and PDF formats.
• Exporting the bill of quantities to FIEBDC-3 format.
• Exporting the information generated with CYPELEC Electrical Mechanisms to the BIMserver.center platform using IFC and GLTF formats. The information can then be viewed by authorised project participants. The information generated by CYPELUX can be used by the following programs:
  • CYPETHERM LOADS
    This program imports the installed lighting power in the building's spaces.
  • CYPELEC Distribution
    This program imports luminaires and automatically assigns and generates the corresponding receivers in their position.

"Installation" tab

The "Installation" tab has a work environment that allows the design of the installation to be carried out quickly and easily, both in a 3D view and in any type of 2D view (such as floor plans and elevations). As a result, the elements in the system can be entered using the most appropriate view at any given time.

This tab displays the following:

• A top toolbar containing the tools for: managing the project parameters, type libraries and catalogues, and configuring the generation of sheets; entering the spaces, design areas and safety or protection elements to be illuminated; entering and editing the luminaires and configuring the daylight calculation, including the automatic distribution tools; accessing the editing tools; creating views and renderings; and analysing and checking the lighting installation.
• The work area, on the right of the screen, where the above-mentioned elements are entered, edited and displayed.
• Finally, on the left side panel, there are several panels with tools for defining the views of the project, managing the visibility of the elements read and own elements, and activating the display of the analysis results.

"Bill of quantities" tab

On the other hand, the "Bill of quantities" tab is used to manage the bill of quantities of the lighting installation, and displays the following:

• A top toolbar containing the tools for creating and editing the bill of quantities, as well as those for managing and creating reports.
• A graphic window with its own toolbar, located on the right-hand side, in which it is possible to view the different elements of the job.
• A specific area for structuring the bill of quantities, on the left-hand side.

"Sheets" tab

Lastly, the "Sheets" tab can create and manage the drawings of the lighting installation, and displays the following:

• A top toolbar with different features, such as creating and managing templates, editing styles, and entering, editing or ordering drawing elements, among other options.
• The main work area, on the right-hand side of the screen, which displays the composition of each of the sheets.
• On the left-hand side are the main tools for managing the sheets and layers of the project, as well as the on-screen display options and the management of snaps by category.

When starting the program and clicking on "New", the program offers users the possibility to create a "New job", which can then be integrated into an existing project in BIMserver.center.

This is done in the "Project selection" window. On the left-hand side, you can log in with a BIMserver.center account.

• On the left-hand side, users can log in with a BIMserver.center account.
• On the right-hand side, the "Select project" option is used to choose an existing project. There is also the possibility to "Create a new project". In this case, the created project will be visible from BIMserver.centre from that moment on.
• The project can also be starting without being linked to the BIMserver.center platform. To do this, simply uncheck the box at the top left, "Link to a BIMserver.center project".

Once the new job has been created, the program interface is accessed, where the graphic window showing the model or models that have been imported stands out. At any time during the project, files can be shared or imported via the "BIMserver.center" group on the top right-hand side.

Importing BIM models

When creating a new job and selecting a project hosted on the BIMserver.center platform from "Select project", the "Import BIM models" window appears, which shows the files contained in that project in IFC format.

The program can include one or more of the existing models in the project. To do this, check the "Import" box and accept it. Users must decide whether the "Type" of each file is "Initiator" or "Additional".

The 3D view of the program will then display the imported models, both from the initiator and additional files. The program can also import the geometry of floors and spaces from the file marked as an initiator using a configuration wizard.

Configuration wizard: selecting standards, downloading catalogues and classifying spaces

Then, from the "Import BIM Models" window, the program opens the "Configuration" wizard, which consists of the following steps:

• In the first step, a list of the floor plans found in the BIM model is displayed. The floor plans to be imported can be selected here. The spaces included in a floor plan that has not been selected will not be imported.

• The next step shows a list of the space types found in the BIM model. Here it is possible to select the space types to be imported. Spaces assigned to an unselected space type will not be imported.

Import results

Finally, in the last step, an "Import results" box is displayed with the information of the processed, created, modified or deleted BIM model elements, including those listed in the table on the right.

General parameters

The available options are as follows:

• General project requirements
• Specific requirements of each zone

Specific requirements of each zone

Allows you to configure the checks to be performed on each type of zone. Subsequently, in the "Zone types" library accessible from the "Project" group or from the inserting or editing panel of each "Zone", these checks can be assigned to the desired zone type.

The program shows with marks in the right-hand column whether the checks are being applied.

When creating or editing each entry in the table, the "Zone check" window opens with the following options:

Without daylight

If this option is selected, the program will not calculate the daylight.

Only calculate the daylight factor

The program will calculate the daylight factor, without including the effect of daylight in the results. The daylight factor expresses the ratio between the illuminance at an indoor point produced by the effect of daylight and the illuminance that would be obtained if there were no obstructions. To calculate it, the program uses a reference CIE cloudy sky that produces a horizontal diffuse illuminance of 10000 lux.

• Reflectance of the façades
  Indicates the reflectance value to be used for the external surfaces of the elements in the job.
• Average ground reflectance (optional)
  By activating this option, the average reflectance value of the ground can be indicated.

Definition by date, time and location / Definition by altitude and azimuth

In these cases, the following features can be edited in the configuration panel:

• Daylight factor
  • Analyse (optional)
    When this option is activated, the daylight factor will be calculated, without including the effect of daylight in the results. The daylight factor expresses the ratio between the illuminance at an indoor point produced by the effect of daylight and the illuminance that would be obtained if there were no obstructions. To calculate it, the program uses a reference CIE cloudy sky that produces a horizontal diffuse illuminance of 10000 lux.
• Date (just in "Definition by date, time and location")
  The time zone, the date of the simulation and the time of the simulation are used together with latitude and longitude to determine the solar angles:
  • Hour range
  • Simulation date
  • Simulation time
• Location
  • Latitude (just in "Definition by date, time and location")
    Angular distance from the job location to the equator’s parallel line.
  • Longitude (just in "Definition by date, time and location")
    Distancia angular desde la ubicación de la obra hasta el meridiano de Greenwich.
  • Altitude (just in "Definition by altitude and azimuth")
    Angle formed between the sun and the horizontal line of the scene.
  • Azimuth (just in "Definition by altitude and azimuth")
    Angle formed between the sun and the southern direction of the scene.
  • Orientation
    The orientation of the building is essential when a daylight calculation is carried out and a sunny sky type is assigned. In these cases, in contrast to cloudy skies, the illumination distribution is not symmetrical around the zenith. The angle describing the orientation corresponds to the offset between the direction of the Y-axis of the scene and north, in a counter-clockwise direction.
    Thanks to the linking of the job with a BIM model, if the orientation is already specified in an IFC file, this parameter will appear directly with the corresponding value.
• Sky model
  • Sky model selection
    The type of sky model to be used in the daylight simulation can be selected from the following:
    • Clear sky without sun
      Corresponds to the CIE clear sky standard without considering direct sunlight illumination.
    • Clear sky with sun
      Corresponds to the CIE clear sky standard including direct sunlight illumination.
    • Partially overcast sky without sun
      Corresponds to the CIE medium sky standard whose lighting conditions are between those of clear sky and cloudy sky. In this case, direct sunlight illumination is not considered.
    • Partially overcast sky with sun
      Corresponds to the CIE medium sky standard including direct sunlight illumination.
    • Overcast sky
      Corresponds to the CIE cloudy sky standard. The sky brightness increases progressively with altitude from the horizon towards the zenith, but does not vary with respect to azimuth. This sky type is commonly used to determine daylight factors.
    • Uniformly overcast sky
      Represents a sky with completely uniform lighting.
  • Turbidity factor (optional)
    By activating this option, the turbidity factor can be defined. The higher the turbidity factor, the greater the atmospheric dispersion. A value equal to 1 indicates an ideal clear atmosphere while values below 1 are physically impossible.
  • Brightness at the zenith (optional)
    Activating this option allows the zenith brightness to be defined. If not directly specified, the zenith radiance is determined from the solar angle and the sky turbidity. The zenith brightness can also be calculated from the horizontal diffuse irradiance. To do so, the corresponding magnitude is selected from the following drop-down menu:
    • Radiance / Irradiance
  • Solar radiance (optional)
    By activating this option, solar radiance can be defined. If not specified directly, it is determined from the solar altitude. If a value of 0 is specified, no sun modelling will take place. The solar radiance can also be calculated from the direct horizontal irradiance. To do this, the corresponding magnitude is selected in the following drop-down menu:
    • Radiance / Irradiance
• Reflectances
  • Reflectance of the façades
    Indicates the reflectance value to be used for the external surfaces of the elements in the job.
  • Above ground reflectance (optional)
    By activating this option, the average reflectance value of the ground can be indicated.

The side of the selected zone will determine the orientation of the X-axis of the layout. The program displays luminaire alignments in the X-direction in red and those in the Y-direction in green.

During the process, the program displays the following dockable window for defining the distribution parameters:

• Lighting type
  • Interior
  • Exterior
  • Emergency
• Luminaire
  • Catalogue / Selection
    Reference to the manufacturer’s catalogue and luminaire model selection. Using the “Select a luminaire from the library” wizard, available on the right, the program allows you to select luminaires from “Manufacturer catalogues” or the “Generic elements library”. These types of elements can be created and edited via the “Catalogues” and “Indoor luminaire types”, “Outdoor luminaire types” or “Emergency luminaire types” options, respectively, available within the “Project” section of the main toolbar on the main interface.
• Axis orientation
  Defines the orientation of the luminaires by applying an individual rotation about their Z-axis. To do this, you specify whether the horizontal plane of origin of the photometric curve is aligned with, or oriented at a specific angle to, the reference line:
  • Aligned
  • Rotated by 90°
  • Rotated 180°
  • Facing 270 degrees
  • With user-defined orientation
• Distribution by zone
  Adjusts the lighting layout settings.
  • Position
    Indicates whether the distribution of luminaires is defined by entering their number or a specific distance between luminaires. The program allows you to "Enter only luminaires that are completely within the zones" by ticking the relevant option. This option automatically excludes any luminaires whose geometry lies partially outside the distribution polygon.
    • By quantity
      The luminaires will be distributed evenly according to the specified number.
      For each direction (X / Y), the following is specified:
      • Alignment
        Specifies whether the luminaires are arranged "Symmetrically", aligned along their "Outer edges", or with their centres aligned with the sides of the rectangle ("Centre-to-centre").
      • Number of luminaires
        Enter the number of luminaires per row.
    • By distance
      A fixed spacing is set between luminaires, measured between centres or between edges.
      For each direction (X / Y), the following is specified:
      • Alignment
        Defines how the luminaires are positioned in relation to the boundaries of the distribution. The luminaires can be arranged "Symmetrically", aligned along their "Outer edges", or with their centres coinciding with the sides of the rectangle ("Centre-to-centre").
      • Spacing
        Indicates whether the distance measures the spacing "Between centres" or "Between edges" of luminaires.
      • Distance
        Enter the distance between luminaires.
• Automatic distribution
  Calculates the optimal number of luminaires required to achieve a target illuminance. To do this, once a luminaire model and a zone have been selected, the program automatically adjusts the distribution parameters to approximate an “Average maintained horizontal illuminance”, which must be entered by the user. The “Estimated illuminance” based on the generated parameters is displayed on the panel.

Once you have confirmed, the program generates and positions the luminaires according to the defined settings. If necessary, the position or properties of the luminaires can be edited individually at a later stage.

Automatic distribution

The "Automatic distribution" option allows you to automatically generate a lighting distribution proposal for all desired areas of the building, for both normal lighting and emergency lighting.

The program generates an optimal distribution of luminaires by selecting the product to be used in each type of space, accessing the catalogue of the chosen manufacturer, and defining both the installation height and the average horizontal illuminance maintained.

The procedure is as follows. When you activate the tool, a window opens with two tabs: "Normal luminaire", which allows you to configure the generation of indoor and outdoor lighting, and "Emergency luminaire", which allows you to configure the generation of emergency luminaires.

Each tab displays a list of all zone types, both interior and exterior, defined in the model. By checking the "Apply" box, the zone type is included in the generation.

By selecting "Edit" for each type of zone, you can specify:

• The luminaire model (defining the type of lighting, the catalogue and the reference). Using the "Select a luminaire from the library" wizard, available on the right, the program allows you to select a luminaire from "Manufacturer catalogues" or from the "Generic elements library".
• The "Height of the installation".
• The desired "Average maintained horizontal illuminance".

The "Assign" option in the top toolbar allows you to assign the data defined in the selected area to the other areas.

Once these parameters have been configured, when you click "Apply" at the bottom of the window, the program automatically performs a "Distribution by zone" of indoor, outdoor and/or emergency luminaire in all the corresponding rooms, applying the criteria defined for each type of zone. All the necessary calculations are performed to determine the number of luminaires to be installed per zone, adapting the distribution to the geometry and shape of the premises.

In order to generate both normal lighting and emergency lighting luminaires simultaneously, the program examines the layout of the normal lighting generated and positions the emergency luminaires accordingly so that they do not overlap.

New view

Enters a new view in the model by marking the points that define its position and direction on the plan.

In doing so, the following features are configured:

• Type of view
  • Perspective
  • Cylindrical
  • Hemispheric fisheye
  • Angular fisheye
  • Ojo de pez planisférica
• Position of the view
  Absolute coordinates of the point defining the direction of the view. The program takes these data from the points marked on the plan, but they can be modified:
  • X, Y, Z
• Vector direction of the view
  Components of the vector defining the direction of the view. The program takes these data from the points marked on the plan, but they can be modified:
  • Vx, Vy, Vz
• Vertical direction of the view
  • X direction
  • Y direction
  • Z direction
• Vertical size of the view
• Horizontal size of the view
• Distance to the view plane
• Reach of the view

These views are represented in the workspace by the symbols of a point and a vector.

Render

Selects a view previously inserted in the model and renders it.

The program will generate the scene with the Radiance analysis engine and display the rendering process and result in a specific window, in which the image is refined through several sweeps.

Rendering configuration

Configures the rendering of scenes.

When rendering, users can choose whether they want to display the scene with normal artificial lighting (interior and exterior), emergency lighting or natural lighting with daylight, as well as the degree of accuracy of the scene.

• Artificial normal lighting / Emergency lighting / Natural lighting
• Rendering parameters (Minimum / Quick / Precise / Maximum precision)

Distribution of calculation points

Proper distribution of the calculation points is essential for obtaining reliable and representative illuminance results. For this reason, and in accordance with the guidelines established in standard EN 12464-1, the program implements a positioning of the calculation points adapted to the geometry and characteristics of the premises where the study is carried out.

The final result meets the following criteria:

• Do not exceed the maximum grid cell size.
• In large enclosures, do not exceed a grid size of 10 metres.
• Ensure regular meshing of the calculation points.

Text size

Using the "Text size" option in the "Own elements" panel, which is located by default on the left-hand side of the interface, the program allows you to adjust the size of the text displayed in the 3D environment. The size is set by entering a percentage of the original size.

Users can adjust the text size to suit the dimensions of the venue. Thus, in large venues, such as warehouses or industrial halls, the text can be enlarged to improve readability, whilst in smaller venues it can be reduced in size to prevent text from overlapping.

You can then select one or more of the following display modes. Multiple options can be selected and overlaid simultaneously, allowing for a more detailed representation of the results.

• Contour plots (optional)
  Displays the contour plot diagram using a colour gradient on the plan view, showing the calculated values. A legend for the diagram, in the form of a colour scale, is displayed at the bottom of the screen.
• Contour lines (optional)
  Displays the contour diagram with the values calculated for each contour line.
• Numerical (optional)
  Displays the calculated numerical values on a grid of points on the plan.

It is also possible to adjust the range of values displayed in the diagrams by entering a "Minimum value" and a "Maximum value" to be plotted, as well as to include the positions of the "worst-case values" obtained in the calculation.

Viewing results and checks on screen

If you hover the cursor over the boundary of an area using the "View results" option, the program displays a text box containing information about the area and parameter values such as the following:

• Maintained average horizontal illuminance
• Total installed capacity
• Installation Energy Efficiency Value (VEEI)
• Unified Glare Index
• Daylight factor (if the calculation has been enabled using the "Daylight" option)

If the option to check for regulatory compliance has been selected in this section, the following information will also be displayed alongside the required values and the compliance check.

For example, for standard EN 12464-1, the following is shown:

• Minimum colour rendering index (Ra) of the installed luminaires
• Minimum maintained illuminance (Em) on the reference surface
• Minimum illuminance uniformity (U0) over the reference surface, for maintained illuminance
• Unified Glare Rating (UGR) limit

Sheets for each zone and calculation area

The program generates supporting documents that include general details and the checks it performs for each area or calculation zone.

To view the breakdown for each zone or calculation area, click on it and select the "View results" option.

Calculation annex

The calculation annex sets out, in addition to the calculated values, the characteristics of the premises together with their standard and emergency lighting systems.

The information collected includes the following:

• Indoor and outdoor lighting
  • Layout of the light fittings
  • Calculation of illuminance and glare
  • Contour map
  • Location of the worst-performing stocks
• Photometric curves
  Curves in the two photometric planes for the luminaires used in the project.
