colleagues,</SPAN></FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=562420714-04072007>It is my pleasure to
announce to you the release of Daylight 1-2-3, a new daylighting/energy analysis
software developed jointly by the National Research Council Canada and Natural
Resources Canada. The tool predicts the daylighting and energy performance of
sidelit and/or toplit private offices, open plan offices, and classrooms.
Daylight 1-2-3 comes with an intuitive graphical user interface and extensive
help files and should take you less than 30 minutes to learn.

<DIV><FONT face=Arial size=2><SPAN class=562420714-04072007>Daylight 1-2-3 uses
a customized version of ESP-r that reads in RADIANCE/DAYSIM-based daylight
coefficients and uses the occupant behavior model Lightswitch to predict the
energy saving potential of automated lighting controls such as occupancy sensors
and photocell-controlled dimming. Simulation outputs include the latest
generation of climate-based daylight performance metrics such as continuous
daylight autonomy, useful daylight index, and daylight saturation percentage as
well as monthly energy loads for heating, lighting, and cooling. The effect of
venetian blinds is modeled using the SKYVISION software. For a full overview of
the software please refer to <A
