36	! Fixed faulty characters
37	!
38	! 4687 2020-09-21 19:40:16Z maronga
39	! Bugfix: values of theta_m_t_prev were not stored for individual surfaces and thus re-used by all
40	! surfaces and buildings, which led to excessive indoor temperatures
41	!
42	! 4681 2020-09-16 10:23:06Z pavelkrc
43	! Bugfix for implementation of downward surfaces
44	!

53	!
54	! 4441 2020-03-04 19:20:35Z suehring
55	! Major bugfix in calculation of energy demand - floor-area-per-facade was wrongly calculated
56	! leading to unrealistically high energy demands and thus to unreallistically high waste-heat
57	! fluxes.
58	!
59	! 4346 2019-12-18 11:55:56Z motisi

66	! 4310 2019-11-26 19:01:28Z suehring

68	! more/less often lead to inaccurate results.
69	!
70	! 4299 2019-11-22 10:13:38Z suehring

147	! Description:
148	! ------------
149	!> Module for Indoor Climate Model (ICM)
150	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
151	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
152	!> This module differs between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine
153	!> thermal comfort
154	!> the heat transfer between indoor and outdoor is simplified
155
156	!> @todo Many statement comments that are given as doxygen comments need to be changed to normal comments
157	!> @todo Replace window_area_per_facade by %frac(1,m) for window
158	!> @todo emissivity change for window blinds if solar_protection_on=1
159
160	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
161	!> @note How to write indoor temperature output to pt array?
162	!>
163	!> @bug Calculation of iwghf_eb and iwghf_eb_window is faulty
