I am aware that there isn't any vegetation scheme in CFD package. So the modeled area in ENVI-met should eliminate any type of vegetation.
yes its possible to validate with those result with cfd but the way to deal with the problem in cfd is a bit different then ENVI-met, however under certain assumption you have to taken when you will deal with cfd .
The Green CTTC (green - cluster thermal time constant ) Method is the thermal model that includes vegetation - mainly trees - influence (including Heat Transfer, Solar Radiation, Humidity, Wind, Evapo-transpiration ) on the thermal conditions. Main co-authors Limor Shashua-Bar, and Milo E. Hoffman (Faculty of Architecture and Town Planning, IsraelInstitute of Technology)and others Main publication:"The Green CTTC Model for predicting air temperature in small urban wooded sites" Building and Environment 37 (2002),1279 -1288.
In any case, I propose to you and others to consider in the warm stations that people will feel the closer as possible to comfortable, when seating in the shade: Lowest Metabolic Rate, or at least walking in the shade. Where, in the cold stations,pedestrians will prefer wind defended sunny places. For thermal comfort evaluation, consider the above, and use the simplest methods for evaluation in the shade, but at least with 1 m/sec for wind speed near pedestrians wearing 0.5-0.7 clo, Where in the cold station, consider 1.2- 1.5 clo or more. in the sunny places with Fanger's Model CONSIDERING ALL THE RELATION,WITH SOLAR RADIATION.
All the best,
