Welcome to this month’s product update for Sefaira Architecture!

This month, we added new daylighting visuals to support your design process, provided more flexible daylighting analysis, and improved model interpretation for SketchUp and Revit.



Daylighting Metrics

Overall daylighting metrics can help you to compare design options and stay on track for daylighting goals. Sefaira recently added the following metrics: Average Daylight Factor, Minimum Daylight Factor, and Uniformity Ratio. We also added helpful new displays for Spatial Daylight Autonomy (sDA) and Annual Sunlight Exposure (ASE).

Per-space analysis

When investigating daylight for your design, whole-building metrics provide an overall picture of performance. From there, it’s useful to zoom into a smaller area of the building, such as an individual room, to view how design changes impact that specific space. Further, many daylighting standards and codes require room-by-room or floor-by-floor analysis.

To support daylight studies that require per-space information, Sefaira now allows you to click on separate regions of the building floor and view area-specific daylight performance.  Currently, the plugin can separate any areas that are built with separate floor planes in SketchUp or Revit. We plan to extend this feature to recognize rooms built in Revit.

DF per room

Variable Work Plane

Depending on your project type and common activities in the space, you may wish to view daylighting outcomes at a certain height. For example, laboratory employees will typically experience daylight at a different elevation than elementary school students. Various daylight standards and codes around the world also specify different work plane heights for simulation. Now, depending on the needs for your project, you can customize the work plane height used for Sefaira’s daylighting analysis.



Sefaira’s Daylighting Visualizations allow you to positively impact design outcomes by providing rapid feedback, embedded inside the design environment. To support that process, we’ve made a number of technical enhancements that provide faster simulation times, without sacrificing graphical quality or simulation accuracy. (A full list of Sefaira’s input assumptions and Radiance settings for daylight analysis is available here on our Knowledge Base.)

Real Time Analysis

A new baseline, ASHRAE 189.1, is now available.  We also added Climate Zones 7 & 8 for all ASHRAE baselines.


SketchUp Plugin Improvements

  • Improved! For users experiencing a poor internet connection, the plugin now runs more reliably.

Revit Plugin Improvements

  • Improved! For users experiencing a poor internet connection, the plugin now runs more reliably.
  • Improved! Now, Sefaira only analyzes Revit elements when they are visible in your current view. This improvement provides support for design options and phasing.
  • Added! Support for Revit 2016.
  • Added! Support for slanted walls.
  • Added! Support for linked models. This functionality is only available for Revit versions 2014 and above. To access this update, you will need to install a new version of the plugin. (For more information on analyzing linked Revit models, please see this article on our Knowledge Base.)

What’s Next?

We’ll continue to improve our daylighting analysis capabilities in Sefaira Architecture. Sefaira is also also working to improve model support for Revit, to the benefit of both our Architecture and Systems products.
