	154	! Description:
	155	! ------------
	156	!> Module for Indoor Climate Model (ICM)
	157	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
	158	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
[4646]	159	!> This module differs between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine
	160	!> thermal comfort
	161	!> the heat transfer between indoor and outdoor is simplified
[4246]	162
[4646]	163	!> @todo Many statement comments that are given as doxygen comments need to be changed to normal comments
[4246]	164	!> @todo Replace window_area_per_facade by %frac(1,m) for window
[4646]	165	!> @todo emissivity change for window blinds if solar_protection_on=1
[4246]	166
	167	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
	168	!> @note How to write indoor temperature output to pt array?
	169	!>
[4687]	170	!> @bug Calculation of iwghf_eb and iwghf_eb_window is faulty
