<p>Sherif,</p>
<p> It is almost always possible to set such things up using
boolean operators in equations that you combine together. To write
the example conditional statement in your email you might do:<br>
</p>
isOcc = GT(occ,0.001)<br>
PPDsmall = LT(PPD,6)<br>
categoryA = AND(isOcc,PPDsmall)
<p>but of course you can combine them all into one equation if you
want:</p>
<p>categoryA = AND(GT(occ,0.001),LT(PPD,6)) <br>
</p>
<p>The result of the equations categoryA will be 1 if both of the
other conditions are met and 0 otherwise. You can then feed the
value of categoryA into an integrator to find out how much time
during the year your building was in that condition</p>
<p>kind regards,</p>
<p> David</p>

<div>I want to make like this table in trnsys using some
functions for greater than or smaller than in equator. for
example if PPD < 6 and signal of occ.=1 then count me the
hours for this condition on all year and so on ...How are
these equations to be like? and if I need to use a specific
type for getting this or just using the equator?</div>
