RE: [EnergyPlus_Support] Properties of Straw bale material

["Mahabir Bhandari" <bhandari@xxxxxxxxxxxxxxxxxxxxxxxxx>]

Thanks Linda. In fact I had looked at this website and PDF file before
posing the question. I could not find all the three values, especially
specific heat.. 

 

I also had looked at another source: 

 

http://www.engr.psu.edu/greenbuild/research_overview.html

 

Insulating value ? Early laboratory tests have found straw walls to have a
range of insulating values from between R-26 [RSI-4.6] to R-33
[RSI-5.8](Commins and Stone 1998). The most definitive test were performed
at Oak Ridge National Laboratories. Measurements there showed the wall to
insulate to R-27.5 [RSI-4.8]. On a per-thickness basis, this is R-1.45 per
inch [0.099 W/m°C] (Christian 1998).

 

The sources differ in values so I was wondering if some used straw bale in
modeling and what were the properties used..

 

Mahabir

I found this by googling "straw bale thermal properties":
