10.0pt;font-family:Arial;color:windowtext'>I am using EE4 to do energy
simulations, as required her for energy grant submissions. It appears to
be basically the same tool as EnergyPro4, with each product adapted to local
conditions. Does anyone have experience (they wish to share) with modeling
Ground Source Heat Pump systems with in-floor heating and 4-pipe fan coil units
for air distribution? The EE4 simulation manuals leave MUCH to be desired, and
the warnings/errors etc. from EE4 are not very useful much of the time. Any
help is greatly appreciated.<o:p></o:p></span></font></p>
