Solar Analysis for Revit (SAR) is our free technology preview where you can easily and iteratively perform solar analysis on the faces of a mass in Autodesk Revit. Using the technology preview can help with photovoltaic system design, shading device design (effective strategies in blocking unwanted solar radiation), and aperture placement (allowing wanted solar radiation). You can visualize and quantify the distribution of solar radiation on various areas of a mass using the flexible analysis visualization capabilities of Revit, taking into account the shading effects from adjacent objects such as vegetation and surrounding buildings in an urban setting.
In September, I posted an update that, among other things, included the downloadable SAR installer from the Autodesk Labs project also includes the Lighting Analysis for Revit.
Lighting Analysis for Revit (LAR) is a full product release for lighting and daylighting analysis that leverages the fast and physically accurate visual simulation engine of A360 Rendering. With LAR, you can automatically generate an analysis and visualize the distribution of light directly in your Revit design model. Currently optimized for LEED daylighting credits, LAR creates 3D views, plans, and schedules needed for LEED submittal. Based on a ‘freemium’ charge model, smaller and low-resolution analyses are always free, so you pay for only more valuable final analysis jobs. For more information see the LAR product page.
Whereas SAR maps the power of the full solar spectrum (UV, Visible, IR) on surfaces, LAR maps the power of the visible light spectrum on surfaces. SAR and LAR both consider shading by visible objects in the scene. SAR does not consider transparency of windows and assumes all windows are 100% transparent. SAR does not consider reflections from surroundings, only direct and diffuse light from the sun. LAR does both sunlight and electric lights (with special config setting), and all materials properties affect light reflections and transmission and shading.
On Friday I posted another update. The SAR functionality was unchanged; however, the LAR functionality was updated to implement a Custom analysis type in the main UI where users can select any time, date, and solar values, as well as set the threshold ranges for schedule calculations and the analysis plane height above the floor. Here is a new dialog image:
Thanks to Product Line Manager, the one and only David Scheer, for the information and image.

A light update is alive in the lab.
