[4750]	41	! - Namelist parameter added to switch-off/on the indoor model during wall/soil spinup
	42	! - Bugfix in window-wall treatment during spinup - in the urban-surface model the window fraction
	43	! is set to zero during spinup, so it is done here also
	44	! - Bugfix in wall treatment - inner wall temperature was too low due to wrong weighting of
	45	! wall/green/window fractions

	178	! Description:
	179	! ------------
	180	!> Module for Indoor Climate Model (ICM)
	181	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
	182	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
[4646]	183	!> This module differs between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine
	184	!> thermal comfort
	185	!> the heat transfer between indoor and outdoor is simplified
[4246]	186
[4646]	187	!> @todo Many statement comments that are given as doxygen comments need to be changed to normal comments
[4246]	188	!> @todo Replace window_area_per_facade by %frac(1,m) for window
[4646]	189	!> @todo emissivity change for window blinds if solar_protection_on=1
[4246]	190
	191	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
	192	!> @note How to write indoor temperature output to pt array?
	193	!>
[4687]	194	!> @bug Calculation of iwghf_eb and iwghf_eb_window is faulty
