[BLDG-SIM] earth-air exchanger (earth channels)

[Richard Heimrath]

Dear Hugues,

there are two different kinds of simulation tools for earth-to-air 
exchanger available:

stand alone simulation software (without the possibility to calculate more 
then the earth-to-air exchanger ):

WKM from Huber (http://www.igjzh.com/huber/)
GAEA from the Uni Siegen 
(http://nesa1.uni-siegen.de/index.htm?/softlab/gaea.htm)
some self made capacitance models from our department (in matlab and fortran)..

some modules or types from simulation tools (with the possibility to 
calculate the hole air system including the building)

Trnsys 15:      Type 160 (S. Holst)
                 Type  260  air-to-soil heat exchangers ("earth channels") 
(P. Hollmuller)
                 Type 556  (from TESS)  Buried Horizontal Pipe
                 http://sel.me.wisc.edu/trnsys/

Smile:          different components (Grund, Pipes,..) for simulating 
air-to-soil heat exchangers

ColSim: Type 32 (air-to-soil heat exchangers ) K. Rittenhofer
