[4750]	30	! - Namelist parameter added to switch-off/on the indoor model during wall/soil spinup
	31	! - Bugfix in window-wall treatment during spinup - in the urban-surface model the window fraction
	32	! is set to zero during spinup, so it is done here also
	33	! - Bugfix in wall treatment - inner wall temperature was too low due to wrong weighting of
	34	! wall/green/window fractions
	35	!
	36	! 4730 2020-10-07 10:48:51Z suehring

	57	!
	58	! 4687 2020-09-21 19:40:16Z maronga
[4687]	59	! Bugfix: values of theta_m_t_prev were not stored for individual surfaces and thus re-used by all

[4442]	74	! 4441 2020-03-04 19:20:35Z suehring
[4646]	75	! Major bugfix in calculation of energy demand - floor-area-per-facade was wrongly calculated

	167	! Description:
	168	! ------------
	169	!> Module for Indoor Climate Model (ICM)
	170	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
	171	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
[4646]	172	!> This module differs between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine
	173	!> thermal comfort
	174	!> the heat transfer between indoor and outdoor is simplified
[4246]	175
[4646]	176	!> @todo Many statement comments that are given as doxygen comments need to be changed to normal comments
[4246]	177	!> @todo Replace window_area_per_facade by %frac(1,m) for window
[4646]	178	!> @todo emissivity change for window blinds if solar_protection_on=1
[4246]	179
	180	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
	181	!> @note How to write indoor temperature output to pt array?
	182	!>
[4687]	183	!> @bug Calculation of iwghf_eb and iwghf_eb_window is faulty
