Dear Rikki
The question is energy saving compared to what?
We can build straw bale houses in low energy standard (according to the minimum energy standards)
or even as passive house. So the energy saving in this case compared to a conventionally insulated house is zero.
If you build with big bales, this may result (theoretically, without including windows) in half the energy consumption of a passive house.
Important is the saving of preliminary energy compared to conventional insulations and the CO2-storage.
According to Werner Schmidt: „Straw Bale Houses need only 10-15% of the preliminary energy of a conventinal house”.
Compared to a concrete house a straw bale house needs 50 times less energy in production (source: GrAT, TU Vienna)

Betreff: [GSBN] energy efficiency.
A reporter for a National newspaper here in Spain wants to write an article on SB. 
She asks me: what is the % of energy savings in a SB house?
Can anyone give me a ball-park figure? o a link to somewhere with reliable data?
I usually compare the centimeters of insulation in a conventional house, to that of SB. But I don’t have the data on what the difference is in real savings…
thanks, Rikki
