<DIV><FONT face=Arial size=2>Dear Trnsys users,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am looking for a methodoly and tools which can be
considered as a good practice for application in building simulation
to model the heat transfer between a building and the ground on which it is
built.</FONT></DIV>
<DIV><FONT face=Arial size=2>I insist on the fact that I need it for a
real building project and not a research project. This means that the
"material" I am looking for should be quite simple to apply but also
accurate enough to give results in which I can be confident. The authority of
its source is therefore also important.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have been already advised to use the European
standard EN ISO 13370. This standard has the advantage to exist, however it is
difficult to apply and I have great doubts on the quality of the results of my
interpretation. More over I did not find yet some one ready to control my
application (!)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This subject is of a very high importance as I
found the results on the simulation I am doing (calculation of summer
indoor conditions without air conditioning) are very sensitive to the numerous
hypothesis.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thank you in advance for your help</FONT></DIV>
