Looking beyond which programs can simulate surface temperatures and thus calculate PMV, I would say the most critical factors in getting a good simulation of conditions in a bazaar are, in order of importance: (1) the large thermal mass effect of the goods, (2) the effective air-change rate of outdoor air, and (3) the internal heat gain of lights, equipment, and people. From my experience, most simulation programs have difficulties in replicating the thermal stability of large thermally-massive structures which bazaars would definitely be. From my experiences going through bazaars and meccas in several Middle Eastern countries, they seem to have their own distinct microclimates. I think if you were able to get the air temperature and maybe humidity profiles correct, the thermal comfort would naturally follow. When you think about it, since 99% of the "stuff" in a bazaar don't receive solar radiation and are also not thermally connected to the outdoor environment, their surface temperatures should be virtually the same as the air temperature.
