[4687]	30	! Bugfix: values of theta_m_t_prev were not stored for individual surfaces and thus re-used by all
	31	! surfaces and buildings, which led to excessive indoor temperatures
	32	!

	138	! Description:
	139	! ------------
	140	!> Module for Indoor Climate Model (ICM)
	141	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
	142	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
[4646]	143	!> This module differs between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine
	144	!> thermal comfort
	145	!> the heat transfer between indoor and outdoor is simplified
[4246]	146
[4646]	147	!> @todo Many statement comments that are given as doxygen comments need to be changed to normal comments
[4246]	148	!> @todo Replace window_area_per_facade by %frac(1,m) for window
[4646]	149	!> @todo emissivity change for window blinds if solar_protection_on=1
[4246]	150
	151	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
	152	!> @note How to write indoor temperature output to pt array?
	153	!>
[4687]	154	!> @bug Calculation of iwghf_eb and iwghf_eb_window is faulty
