Adding Lambda Values for Passivhaus

Question

When you create a wall style and other styles (roof or slab) for a Passivhaus project  you cannot do this in the way that you need to.

If you are using traditional timber framing with insulation there is no way to add the Lambda value for the both the timber and the insulation used within the timber framing.

See attached image.

If you are using a SIPS panel then you can readily do this. But check out  some of the construction methods here and you will see the need for this to be amended.

For situations where you need a lambda value of a combined framing and insulation component, just create your own in the Wall tool prefs. First, use an online calculator to get your combined value based on timber size and spacing and type and thickness of insulation, and then use the 'Look Up Lambda Value' dialog to generate it for your particular component. Or, if you need to use the value more than once, edit the System Set and add it there for future use.

in 2017 at least, there is a lambda value listed for wood framing + mineral wool insulation, but I doubt it would be sealed properly for passivhaus based standards.
