How it Works

To use LightStanza, just upload your 3D model to the cloud-based application, iterate with different materials, blinds operations, sky types, and other properties, and then rapidly simulate content! This simple process allows users to generate and share LEED v3 and v4 scorecards, annual metrics, point-in-time renderings and illuminance grids, and much more!

Begin by uploading your 3D model to the LightStanza interface. This model was designed by RNL Design of Denver, CO.

Apply different materials like glass, opaque, translucent, and even daylight products to your model. These materials are completely customizable with basic view for quick edits and advanced Radiance view for experts who want complete control of simulation parameters.

Iterate with more design options like your model's location and north angle. Changing north angle is helpful when testing similar spaces like offices or classrooms that span across different facades.

Even apply different blinds to the window groups that LightStanza automatically identifies for you (outlined in white above)! Identifying window groups is required for a compliant LEED v4 Spatial Daylight Autonomy score.

Generate results like illuminance grids or renderings at single points in time, as animations throughout the day or at key times, or over the entire year.

Renderings are great for looking at different materials' glare mitigation effectiveness. The image above on the left shows a 100% daylight glare probability score when using clear glass on the windows. On the right, dynamic glass brings that score down to 52%!

With the click of a button, generate a detailed USGBC-approved LEED v4 Daylight Credit Report with both Options 1 and 2 to choose from. You also have the option to generate LEED 2009 Daylight Factor reports.

Continue to iterate with different designs and results, tracking your activity with the activity bar!
