Calculating partial models to evaluate design changes.

Background Information

When modifying the lighting layout for a single space in a larger building, you can recalculate the individual space, without recalculating the entire model. This approach will allow the calculation to complete much faster, allowing for different design options to be compared more efficiently.

Steps to refine the lighting layout for a single space

Step 1: Identify and Select Fixtures for Adjustment

1. Review your initial lighting simulation results.
2. Select the fixtures within the specific space you want to change.

Step 2: Make adjustments to the selected fixtures

1. Make any necessary changes to the lighting layout to improve the results. This can include relocating, re-aiming, and even swapping out the IES file to simulate different luminaire types.

Step 3: Recalculate Only the Space of Interest

1. Right-click on the calculation grid within the modified space.

   Select the option to "Calculate Space".

   • Advantage: This will complete the simulation much faster than recalculating the entire building, giving you a quick answer to see if the new fixture is a better choice.

Step 4: Review and Verify New Results

1. Once the simulation is complete, view the results in your lighting plan.
2. The scope box will be enabled, automatically cropping the view to show results for the specific space you just calculated.
3. Review the new results: Use the compare tool to evaluate how the updated layout compares with the original one.

Step 5 (Optional): Iterate and Refine

1. You can continue this process for additional iterations, calculating one or multiple spaces at a time to quickly test different fixture choices or layouts.
   • Example: You can delete a fixture to see the effect and then recalculate just that space.

This targeted approach allows you to quickly iterate and refine your design without the wait time associated with recalculating the entire floor plan.
