good after noon everybody

I really need your help and expertise, I need to calculate the amount of heat transfer for a vehicle's cabin but I am facing some troubles finding the heat coefficients for the parts such as the roof, windows,......etc. I also need the heat coefficient for the air flowing around the car, is there any tables I can directly take these values from or do I need to make an assumptions and calculate the heat transfer coefficient for the air flow based on its nature ( laminar or turbulent).

please I need your advice and it is urgent, I really appreciate your support.
(p.s. my apologizes for any lingual mistakes)
