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

87	!
88	! 4441 2020-03-04 19:20:35Z suehring

90	! leading to unrealistically high energy demands and thus to unreallistically high waste-heat
91	! fluxes.
92	!
93	! 4346 2019-12-18 11:55:56Z motisi

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).
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
189
190	!> @todo Many statement comments that are given as doxygen comments need to be changed to normal comments
191	!> @todo Replace window_area_per_facade by %frac(1,m) for window
192	!> @todo emissivity change for window blinds if solar_protection_on=1
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	!>
197	!> @bug Calculation of iwghf_eb and iwghf_eb_window is faulty
