I have been experimenting using Google Docs to create a spreadsheet for the levelling exercise. It does not have the functionality of Excel, but is adequate for doing simple equations. The example I have done is available for the students through the Moodle course site

I took this photo on the nokia phone whilst walking into work and uploaded it to vox at the same time.

You may have to zoom in to see the patterns of the framing coming through. The theory of pattern staining is to do with difference of insulation in terms of thermal bridging. I would guess that the cladding is something like Hardietex direct fixed to the studs.
Reids Concrete Panel House guide describes the k value:

2.2.2 Thermal Conductivity (k)
Thermal conductivity is defined as the ability of a
material to conduct heat or, more clearly defined as,
a physical constant for a quantity of heat that passes
through a volume of a substance in a unit of time for a
unit difference in temperature.
Thermal Conductivity has the symbol - k

2.2.3 Solid State R-values
R-values are a measure of the resistance to heat
transfer. If a material has a high R-value then it has
greater insulating properties.

R-values are used to establish compliance with the

New Zealand Building Code in regards to the thermal
efficiency of a building.
R-values for a single material is given by the equation:
R = L/k
Where: L = Material thickness (m)
k = Material thermal conductivity (m2K/ W)
Where a wall section is made from a composition of
different materials (including air gaps), the R-value of
each material is calculated and summed for a total
value through the wall.
NZS 4218:2004 requires buildings with more than
30% total wall area in glazing to use calculation or
computer modelling methods.
