[Equest-users] External Wall Calculation

Scott,

Thanks for the explanation, at least now I know I shouldn't bother banging my head against the wall on this one.  Does anyone have any tips for changing infiltration CFM/SF of exterior wall without going through each zone and manually calculating it?

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.
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.

Hello All,

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?
