[4687]	27	! Bugfix: values of theta_m_t_prev were not stored for individual surfaces and thus re-used by all
	28	! surfaces and buildings, which led to excessive indoor temperatures
	29	!

[4681]	31	! Bugfix for implementation of downward surfaces

[4646]	43	! Major bugfix in calculation of energy demand - floor-area-per-facade was wrongly calculated
	44	! leading to unrealistically high energy demands and thus to unreallistically high waste-heat

	135	! Description:
	136	! ------------
	137	!> Module for Indoor Climate Model (ICM)
	138	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
	139	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
[4646]	140	!> This module differs between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine
	141	!> thermal comfort
	142	!> the heat transfer between indoor and outdoor is simplified
[4246]	143
[4646]	144	!> @todo Many statement comments that are given as doxygen comments need to be changed to normal comments
[4246]	145	!> @todo Replace window_area_per_facade by %frac(1,m) for window
[4646]	146	!> @todo emissivity change for window blinds if solar_protection_on=1
[4246]	147
	148	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
	149	!> @note How to write indoor temperature output to pt array?
	150	!>
[4687]	151	!> @bug Calculation of iwghf_eb and iwghf_eb_window is faulty
