Re: A question about high thermal storage wall

["KCR" <Rauch-Muenster@xxxxxxxxxxx>]

Hi Bo,

how to deal with the additional concrete inside walls will be by fact a question 
of the dimensions of your simulation model, i.e. the number of heat balance 
equations. You will understand what I mean when you will have a look to the 
paper of Borresen. I believe that you have also to think about your general 
concept for the construction of your passive solar house. In recent papers there 
had been many details (for practical purposes) and a lot of theoretical 
approaches to investigate such construction in harmony with the nature.
Perhaps the solution of your computational investigation can be given by the 
US-program BLAST.
I wish you a lot of fun with the research of all that papers which are given in 
the annex.
Kind regards
