    I have the same question like you. have you received any answer ? what is with the printout with the different layers of wall construction ? How is complete U?
    Do the algorithm take the rightly U ? or is it not really exact ? How to ad new wall systems in the library ?

    please help me, Juergen

    To add materials and constructions you have to edit the constructions.xml file in the Revit install directory. Have you guys taken a look at it? You will need a little prior experience editing XML but its pretty straight forward.

    Could you elaborate some more on this?

    Did you look at the file?

    Materials are defined with the the material definitions. example "R-5, 1 in insulation board". make sure the ID is unique, follow the examples in the file for naming convention. As with any markup language only change what is inside the start and end tags <example>edit_this</example> or in the case of the ID's the quotes " "

    Code:
      <Material id="mat-AI01">
        <Name>R-5, 1 in insulation board</Name>
        <Description>R-5, 1 in (25 mm) insulation board</Description>
        <Thickness unit="Meters">0.0254</Thickness>
        <Conductivity unit="WPerMeterK">0.03</Conductivity>
        <Density unit="KgPerCubicM">43</Density>
        <SpecificHeat unit="JPerKgK">1210</SpecificHeat>
      </Material>
    so define your materials if they do not already exist. 90% of the materials commonly used should already exist.
    Then define your construction:

    Code:
      <Construction id="BBW85-D" surfaceType="ExteriorWall">
        <Name>Brick / block wall</Name>
        <Description>Brick / block wall</Description>
        <LayerId layerIdRef="lay-BBW85-D"/>
        <U-value unit="WPerSquareMeterK">0.5416</U-value>
      </Construction>
    Give it a unique ID and define it as InteriorWall, ExteriorWall etc. See other constructions for examples.

    Then define the layering of the construction from outside-to-inside, so "mat-AF01" is the outside surface of the wall. Layer ID should match the construction ID and referenced material ID should correspond to the material definitions.

    Code:
      <Layer id="lay-BBW85-D">
        <MaterialId materialIdRef="mat-AF01"/>
        <MaterialId materialIdRef="mat-AM01"/>
        <MaterialId materialIdRef="mat-AF04"/>
        <MaterialId materialIdRef="mat-AI01"/>
        <MaterialId materialIdRef="mat-AM13"/>
        <MaterialId materialIdRef="mat-AF04"/>
        <MaterialId materialIdRef="mat-AG01"/>
        <MaterialId materialIdRef="mat-AF02"/>
      </Layer>
    Give it a shot, let me know how it goes.

    Yes, I have looked at this file more then once... Never dared to mess with it.
    But I'll try to give it a go...

    In any case, +REP, PotM and bookmarked!
