[BLDG-SIM] Lightswitch Wizard: Daylighting Analysis Software for the Initial Design

[Reinhart, Christoph]

 Dear colleagues,

The National Research Council Canada and Natural Resources Canada have
released an online RADIANCE-based daylighting analysis tool called the
Lightswitch Wizard www.buildwiz.com <http://www.buildwiz.com> . 

The tool has been developed to support daylighting-related design decisions
in commercial buildings during an early design stage. It offers a
comparative, reliable, and fast analysis of the amount of daylight available
in peripheral private offices as well as the lighting energy performance of
automated lighting controls (occupancy sensors, photocells) compared to
standard on/off switches. Blinds are either manually or automatically
controlled. 

Simulation results are based on pre-calculated RADIANCE simulations which
are coupled with an empirical model that mimics manual lighting and blind
control in single offices. Further information is provided in the online
technical background, and glossary sections.

A simulation should take between 20 seconds and 3 minutes to run, assuming
moderate traffic on the server and a fast internet connection. 

Your comments/suggestions are appreciated. Greetings from Ottawa,

Christoph
