day-lighting controls be considered for LEED certification under “Energy
& Atmosphere – Optimize Energy Performance”? If so where
should the light sensor be located in the space? Is there any energy code
that allows credit for day-lighting controls? The DOE2 program allows two light
sensors per space. Supposing the two sensors are located 5 ft and 10 ft
from the window. Is the average daylight at these two points used in
determining the reduction in artificial lighting?</span></font><o:p></o:p></p>

program expects zones to have 6 surfaces defined with X,Y,Z coordinates and
reflectance values for day-lighting analysis. Ignoring this produces
warning messages but the results show a reduction in artificial lighting
energy. For day-lighting analysis we only enter into DOE2 the X,Y
coordinates of the window origin relative to the wall and also the wall and
window dimensions. Can we assume that the energy savings results from the
DOE2 program are on the safe side (the actual energy saved is more) when we use
the program without all the surfaces and coordinates?</span></font><o:p></o:p></p>
