style='font-size:10.0pt'>Here’s what we do for such spaces. First
calculate the space stratification using the Effective Sensible Heat Gain (ESHG)
method. This will provide data on temperatures in the occupied zone and temperatures
of air being exhausted from the space. Use the space exhaust temperature as the
temperature set point in DOE-2 or transys. This should provide a fairly
accurate model, you can then study the performance. I also think that IES can
calculate stratification in spaces.<o:p></o:p></span></font></p>
