<P class=MsoNormal style="TEXT-ALIGN: justify"><SPAN
style="FONT-FAMILY: Arial"></SPAN><SPAN style="FONT-FAMILY: Arial">The National
Research Council Canada and Natural Resources Canada have released an online
RADIANCE-based daylighting analysis tool called the <I>Lightswitch Wizard </I><A
href="http://www.buildwiz.com">www.buildwiz.com</A>. </SPAN></P>
<P class=MsoNormal style="TEXT-ALIGN: justify"><SPAN
style="FONT-FAMILY: Arial"></SPAN><SPAN style="FONT-FAMILY: Arial">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. </SPAN></P>
<P class=MsoNormal style="TEXT-ALIGN: justify"><SPAN
style="FONT-FAMILY: Arial"></SPAN><SPAN
style="FONT-SIZE: 9pt; FONT-FAMILY: Arial">S</SPAN><SPAN
style="FONT-FAMILY: Arial">imulation 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.</SPAN></P>
<P class=MsoNormal style="TEXT-ALIGN: justify"><SPAN
style="FONT-FAMILY: Arial"></SPAN><SPAN style="FONT-FAMILY: Arial">A simulation
should take between 20 seconds and 3 minutes to run<SPAN
class=092521817-03062003>,</SPAN> assuming moderate traffic on the server and a
fast internet connection. </SPAN></P>
