There are a lot of formulas used in this process, @mlk but you can see the source code for the temperature profile across window constructions (the most complex case) here:
def temperature_profile(self, outside_temperature=-18, inside_temperature=21,
wind_speed=6.7, solar_irradiance=0,
height=1.0, angle=90.0, pressure=101325):
"""Get a list of temperatures at each material boundary across the construction.
Args:
outside_temperature: The temperature on the outside of the
construction [C]. (Default: -18, consistent with NFRC 100-2010).
inside_temperature: The temperature on the inside of the
construction [C]. (Default: 21, consistent with NFRC 100-2010).
wind_speed: The average outdoor wind speed [m/s]. This affects outdoor
convective heat transfer coefficient. (Default: 6.7 m/s).
solar_irradiance: An optional value for solar irradiance that is incident
on the front (exterior) of the construction [W/m2]. (Default: 0 W/m2).
height: An optional height for the surface in meters. (Default: 1.0 m).
angle: An angle in degrees between 0 and 180.
* 0 = A horizontal surface with the outside boundary on the bottom.
* 90 = A vertical surface
* 180 = A horizontal surface with the outside boundary on the top.
