29	! 4750 2020-10-16 14:27:48Z suehring
30	! - Namelist parameter added to switch-off/on the indoor model during wall/soil spinup
31	! - Bugfix in window-wall treatment during spinup - in the urban-surface model the window fraction
32	! is set to zero during spinup, so it is done here also
33	! - Bugfix in wall treatment - inner wall temperature was too low due to wrong weighting of
34	! wall/green/window fractions
35	!
36	! 4730 2020-10-07 10:48:51Z suehring
37	! Bugfix - avoid divisions by zero

56	! Fixed faulty characters
57	!
58	! 4687 2020-09-21 19:40:16Z maronga
59	! Bugfix: values of theta_m_t_prev were not stored for individual surfaces and thus re-used by all
60	! surfaces and buildings, which led to excessive indoor temperatures
61	!
62	! 4681 2020-09-16 10:23:06Z pavelkrc

73	!
74	! 4441 2020-03-04 19:20:35Z suehring
75	! Major bugfix in calculation of energy demand - floor-area-per-facade was wrongly calculated
76	! leading to unrealistically high energy demands and thus to unreallistically high waste-heat
77	! fluxes.
78	!
79	! 4346 2019-12-18 11:55:56Z motisi

85	!
86	! 4310 2019-11-26 19:01:28Z suehring

167	! Description:
168	! ------------
169	!> Module for Indoor Climate Model (ICM)
170	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
171	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
172	!> This module differs between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine
173	!> thermal comfort
174	!> the heat transfer between indoor and outdoor is simplified
175
176	!> @todo Many statement comments that are given as doxygen comments need to be changed to normal comments
177	!> @todo Replace window_area_per_facade by %frac(1,m) for window
178	!> @todo emissivity change for window blinds if solar_protection_on=1
179
180	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
181	!> @note How to write indoor temperature output to pt array?
182	!>
183	!> @bug Calculation of iwghf_eb and iwghf_eb_window is faulty
