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

[4442]	88	! 4441 2020-03-04 19:20:35Z suehring
[4646]	89	! Major bugfix in calculation of energy demand - floor-area-per-facade was wrongly calculated

	181	! Description:
	182	! ------------
	183	!> Module for Indoor Climate Model (ICM)
	184	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
	185	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
[4646]	186	!> This module differs between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine
	187	!> thermal comfort
	188	!> the heat transfer between indoor and outdoor is simplified
[4246]	189
[4646]	190	!> @todo Many statement comments that are given as doxygen comments need to be changed to normal comments
[4246]	191	!> @todo Replace window_area_per_facade by %frac(1,m) for window
[4646]	192	!> @todo emissivity change for window blinds if solar_protection_on=1
[4246]	193
	194	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
	195	!> @note How to write indoor temperature output to pt array?
	196	!>
[4687]	197	!> @bug Calculation of iwghf_eb and iwghf_eb_window is faulty
