Defining your setpoint as a SCHEDULE in TRNBuild simply allows you
to set a value that depends upon the time of day. Defining your
setpoint using an INPUT allows you a good bit more flexibility. You
could define your equation as follows:<br>
<br>
Tset_heat = 24*occ + 12*(1-occ)<br>
<br>
occ would have to be defined in another equation or perhaps a Type14
forcing function to have a value of 1 when the building is occupied
and a 0 when it is not occupied.<br>

<br>
I trying to calculate the cooling demand of my office building in
TRNBUILD and would like the cooling demand to response according
to my occupancy schedule(less cooling at night and more cooling at
day). I try to define the set temp at the cooling type by i not
sure which one should i use (schedule or input?) And also the
equation behind it, because when i enter like for instance <u>24degree(set
temp) *occupancy schedule+0</u>, i would get 0 degree when there
is no occupancy. <br>
<br>
Appreciate your kind assistance on this<br>
