[EnergyPlus_Support] Using BEopt for Rammed earth.

["Joe Huang YJHuang@xxxxxxxxxxxxxxxxxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

What problem are you having in modeling rammed earth?  Its thermal properties are simply that of  soil, which would vary of course from place to place.  In general  I've used a conductivity of 2.85 (W/m2-K), density of 2000 kg/m3, and specific heat of  837Joule/kg-K of for dry soil (all converted from original IP units of 0.5, 125, and 0.2, respectively).  If it's damp soil, the conductivity would increase or double at most.

Weather data is very scarce for Bhutan, which has only one international, i.e., receives flights from outside the country, airport at Paro. There isn't enough weather data to create a "typical year" weather file, but I can offer you the weather file for Paro 2013  here .

Dear Sir/Madam,

                        I am currently studying in College of Science and Technology(CST) as a civil engineerinf student. Me and my group is currently undergoing a project on "Net Zero Energy Building Model in CST". 

Our research has faced lots of challenges out of which the simulation software (ie. BEopt) we are using does not have rammed earth material in the wall section of the model. Also we cannot find the weather data of our country Bhutan. I would be very grateful if any one can help us to solve these problem.
