[Bldg-sim] Natural Ventilation

[Cheney]

Hi Sambhav,

For natural ventilation analysis, you may start with some field measurements
or wind tunnel test  which can help you decide the boundary condition
precisely. Some key parameters, such as prevailing wind direction,
representative wind speed, air temperatures, surface temperatures, etc. are
all important components of the boundary condition. Meanwhile, building
geometry, building materials, surrounding buildings, topography, etc.
may influence the boundary condition significantly. You will have a holistic
consideration of all these variables and make reasonable simplification to
work out the boundary condition.

Regards,

Cheney
