The DOE-2 BDL expression module does not allow parent components to
reference keyword values of their child components. Back when the
expression module was developed, this limitation was put in place to
minimize changes required to the BDL file reading & defaulting
mechanism and also to simplify expression dependencies evaluation and
minimize the likelihood of circularities defined when two components
can each reference data of the other.<br>
The ruleset processing mechanism that provides the foundation of the
compliance analysis and QC reporting features of eQUEST does include
the ability to reference components in both directions (children
referencing parents as well as parents referencing children), but to
date this capability has not been extended for use in performing
parametric runs or facilitating semi-automated edits to building models.<br>

<div>Hello All,</div>

<div>Does anyone know of a way I can reference a child code word? My
specific situation is that I want my infiltration to be controlled via
a global parameter that represents the infiltration in terms of CFM/SF
of Exterior wall. I want to be able to parametrically
change this value so I have to do it in DD Edit. The problem is that
infiltration is a zone keyword that is the parent of the exterior
wall. It wouldn't be an issue the other way around because I could
just use the #P("keyword"). Any ideas on how I can reference
the child using DOE2 language?</div>
