The only way to prevent parts of a rule of being evaluated is to use
control facts:
when
SomeControlFact( someCondition == true )
eval( ..someHeavyEvaluation... )
then
In the above case, the eval will only be evaluated when the control fact
matches.
Another way of doing it is moving your expensive "calculation" to the
consequence of a rule and inserting the result as a fact. This way you have
control of when it is executed.
