the LPD doesn’t include the reduction due to occupancy sensors. However
in saying this do we need to put in the reduction in the mandatory areas as it
is going to be roughly the same savings applied to the baseline and proposed building?<o:p></o:p></span></p>

I am a little confused as to what areas I can take claim for having occupancy
