[EnergyPlus_Support] A question about how to define the convection conefficient

[wanglei <wangleihello@xxxxxxx>]

Dear all
  I have a question about how to define the convection conefficient, when the altitude is about 5000m. In this case, the density of air is much less than the standard value, so I want to selcet a appropriate aLgorithm to calculate this value.
After I reading the EngineeringRefernce doucumnet, I found that all of the six models for estimation the convection conefficient didn't take into account the effect of air density.
 
Anyone can tell me how to deal with this problem.
Thanks Very Much
Lei Wang
