Daylighting Analysis for Revit from Autodesk Labs

From the Autodesk Labs website...

The Revit 2014 Daylighting Analysis (RDA) plug-in uses the Autodesk 360 Rendering cloud service to perform very fast and physically accurate daylighting analyses from within Revit. In this first release of the plug-in, we have enabled it to provide LEED IEQc8.1 2009 results for most models in less than 15 minutes once the analysis is started. For a limited time you can use this absolutely free*!

In case you missed the news from earlier this year — Autodesk Rendering is an extremely fast cloud rendering service that also includes illuminance results that are comparable to Radiance with the exception of one aspect — speed. The Autodesk Rendering cloud service accounts for all light bounces and is about 24x faster than Radiance. More details on this valuable service can be found in this blog post.

The Revit 2014 Daylighting Analysis plug-in (RDA) is specifically designed for architects to be able to use without learning the difference between the Perez or CIE's sky models, direct normal incident or direct horizontal radiation. Just specify if you want to analyze the whole building, a single or multiple floors, and kick-off the analysis. If you want more control of those parameters, you can use Revit's existing 360 Rendering Advanced Illuminance feature detailed in this blog post.

The RDA plug-in will help you succeed with your daylighting design challenges as it generates the necessary daylighting simulation results and keeps track of LEED 2009 IEQc8.1 performance during project design.

Results are presented on your Revit elemental model using the Analysis Visualization Framework (AVF) so you can see exactly how daylight is interacting with your Revit model. A room schedule is generated with the necessary results for a LEED submittal. You can also choose to include or not include rooms as LEED regularly occupied spaces and specify automated shades or other details.

For more details on how to best set up a Revit model for daylighting analysis see the instructions on the Building Performance Analysis Certificate site.

There's more information available on the Autodesk Labs website.
