Electric Lighting Help Guides

The Activity Bar (on the right side of your design screen) is where new activities are started, previous activities are referenced, model edits are listed and comparison reports are kicked off. 

1. Renderings/Animations – These come from individual point-in-time renderings and animations. To play a rendering/animation, click the New Simulation button in the top of the activity menu.
   1. Camera Tools – You can customize the way you view your renderings in the 3D viewer with Camera Tools. (Hover over the activity you want to see in the activity menu then click the building icon)
      1. Exposure – You can manually adjust the exposure of your renderings in order to increase or decrease the amount of light per unit area. LightStanza uses Reinhard tone mapping for adjusting exposure. 
      2. Contrast – Adjusting the contrast of your image will increase or decrease the difference between light and dark in your renderings. 
      3. False Color – In the 3D viewer, you have the option to view your renderings in False Color mode for a more quantitative view of your images.
         1. Luminance Bounds – Changing your luminance sets what luminance values each color in your image represents. Adjust this to focus on very bright or very dark areas. 
         2. Log Scale – Adjusting your log scale sets scaling of your false color heat map. 
         3. Contour Lines – This is another way to look at your false color rendering. Contour lines trace the different luminance thresholds in your rendering, using the false color legend.
            1. Line spacing – Changing your line spacing sets the density of contour lines in your image. 
2. Illuminance Grids – These come in the form of Point-in-time Illuminance Grids and animations. Clicking one of these activity cards will place the result inside of your 3D model. 

1. View model edits – By clicking the “Show model edits” button at the top of the Activity Bar, you can see edits you’ve made to your model in the left toolbar. You can also revert to previous model states using the revert button on a history card, and you can save any state of your design to a new design using the save button on a history card. 
2. Starting a comparison – By clicking the “Compare Activities” button at the top of the Activity Bar, you can compare two different simulations at once by selecting two activities from the list of simulations below.

1. Starting a new activity – At the top of the Activity Bar, there is a “New” dropdown menu with the following options:
   1. Rendering/Animation – Renderings can be made on the fly or from your list of viewpoints in the left Viewpoints panel. To make renderings on the fly, simply move your 3D viewer screen to the angle and location that you want, and when you start a new rendering at the exact spot. After clicking “Rendering/Animation” in the dropdown menu, you will be presented with a new set of simulation options:
      1. Check the “Emergency Lighting Calculation” box under Simulation Options to create a rendering from luminaires designated as emergency. Leaving this box unchecked will create a rendering of all normal lighting within the set viewpoint.
      2. Simulation Quality depends on a list of Radiance settings. These settings will be shown as a tooltip next to the Simulation Quality setting in the header.
         1. “Draft” quality is good for faster simulation
         2. “High” and “Very High” quality renderings will be more accurate for things like reports.
         3. You also have the option to set “Custom” quality settings. Simply click “Show Quality Details” and edit your Radiance parameters directly. You can hide these details by clicking “Hide Quality Details.”
            1. Camera Settings – These settings allow you to adjust several options for you rendering/animation.
            2. Field of View – Adjusting these settings will change the X and Y lens angles. Both the X and Y default angles are 180.
            3. Super Sampling – Setting this percentage determines the original size before scaling to your target resolution. The larger this percentage, the crisper your images will be. 
            4. Resolution – Adjusting of the resolution will change the quality, in pixels, of your renderings.
            5. Section Cut – By simulating with a section cut, you can cut into your 3D model to easily view daylight performance in your building.
            6. Analysis Viewpoint – The analysis will be performed at the selected viewpoint.
         4. Camera Settings
            1. Lens
               1. Perspective lens resemles the way the human eye would see a space.
               2. Hemispheric lens uses a wide angle similar to a fisheye lens.
               3. Cylindrical lens has a panoramic look. 
            2. Field of View – Adjusting field of view will change X and Y lens angles. Different lenses (above) will have different default angles. The minimum value for X and Y is 1°. The maximum value for X or Y is 180° for hemispheric and cylindrical lenses, and 175° for perspective lens.
            3. Super Sampling has to do with the original size of your images before scaling to your target resolution. The larger this percentage, the crisper your images will be. For speed, choose smaller percentages.
            4. Resolution changes the quality, in pixels, of your rendering. 

1. 1. Grid Illuminance – This option will provide electric lighting calculations.
      1. Simulation Options – Leaving this section at its default will produce a normal electric light calculation. Checking the “Emergency Lighting Calculation” box under Simulation Options will provide an emergency lighting calculation activity card.
      2. Grid Settings – “Unit” will adjust the lighting measurement unit between Lux or Footcandle (FC). “Point Spacing” allows you to adjust the spacing between grid points for the calculation. “Scale” allows you to choose a graphical scale to accompany the results. 
      3. Simulation Quality depends on a list of Radiance settings. These settings will be shown as a tooltip next to the Simulation Quality setting header.
         1. “Draft” quality is good for faster simulation. 
         2. “High” and “Very High” quality renderins will be more accurate for things like reports.
         3. You also have the option to set “Custom” quality settings. Simply click “Show Quality Details” and edit your Radiance parameters directly. You can hide these details by clicking “Hide Quality Details.”
            1. Camera Settings – These settings allow you to adjust several options for you rendering/animation.
            2. Field of View – Adjusting these settings will change the X and Y lens angles. Both the X and Y default angles are 180.
            3. Super Sampling – Setting this percentage determines the original size before scaling to your target resolution. The larger this percentage, the crisper your images will be. 
            4. Resolution – Adjusting of the resolution will change the quality, in pixels, of your renderings.
            5. Section Cut – By simulating with a section cut, you can cut into your 3D model to easily view daylight performance in your building.
            6. Analysis Viewpoint – The analysis will be performed at the selected viewpoint.
