New SPOT Pro version released!

Fellow Radiance enthusiasts,

A new version of the SPOT Pro daylighting and lighting design and analysis
software is now available! Visit SPOT home

to learn more about SPOT v5.02 and download the software.

SPOT Pro is a Windows-based stand-alone lighting and daylighting design
interface to a powerful Radiance ray-tracing engine that sits, accessible,
behind the scenes. SPOT Pro has a number of unique simulation capabilities:

   - *Automated annual metric reports - compare various daylighting metrics
   with standard daylighting reports for LEED (v4, 2009), CHPS, IgCC, UDI PBSP
   and a robust SPOT daylight performance report.*
   - *Optical daylighting system annual simulation* - SPOT uses "system
   BSDF" files to describe Complex Fenestration Systems, like LightLouver or
   Tubular Daylight Devices, and perform annual Climate Based Daylight
   - *Accurate Simulation of photosensor controlled electric lighting*
- SPOT simulates
   the actual photosensor system response, lets you refine the control system
   settings, and provides an annual simulation of the interaction between
   electric lighting and daylighting. For those aiming for truly accurate
   simulation, this is the *only tool* that directly simulates the
   photosensor signals rather than using a workplane illuminance proxy, and
   that accounts for the interaction of electric light feedback on common
   closed-loop control systems.
   - *Output to EnergyPlus and DOE-2* - After optimization and simulation
   of the photosensor system, SPOT provides annual LPD multiplier schedule
   output files for both DOE-2 and EnergyPlus.
   - *Shade control simulation* - both automated/photosensor-based control
   and a range of unique manual shade control algorithms are available
   - *"Design Day" calculations* - results showing average "design day"
   conditions (calibrated to climate data) rather than a specific weather
   condition in an hourly weather file.
   - *Internal Geometry Modeler* - The internal modeling tools are fairly
   robust, with blocks, sloped ceilings, monitors, and sawtooth geometries
   available, yet still easy and quick to use with no CAD experience
   necessary. Sketchup models can be imported into the software behind the
   - *Material Database and Editor * - New material database allows colors,
   patterns, glass, metals, and BSDF files to be assigned to your model's
   - *Improved Renderings -* The use of materials and patterns greatly
   improve the quality of the perspective and sectional renderings.

The SPOT user manual

is an excellant resource and provides detailed information about the
software. This SPOT webinar <>

also provides a good introduction to the software.

We had a great workshop at LightFair in San Diego this year and are
offering the same workshop online as a series of 3 free webinars, as
scheduled below:

- SPOT Pro daylighting design and analysis. Tuesday, June 21, 10AM MDT
- SPOT Pro materials and electric lighting design and analysis. Tuesday,
June 28, 10AM MDT
- SPOT Pro photosensor system design and optimization: Tues, July 5, 10AM

Attend a webinar and recieve $100 off a SPOT Pro license purchased within
30days! E-mail [email protected] if you are interested in
joining one of the LightFair workshop webinars or in scheduling a personal
SPOT webinar for your own company.

Join the growing list of design professionals and Universities using SPOT
to optimize daylighting and electric lighting designs.

Happy Simulating!
