127	! Description:
128	! ------------
129	!> Module for Indoor Climate Model (ICM)
130	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
131	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
132	!> This module differs between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine
133	!> thermal comfort
134	!> the heat transfer between indoor and outdoor is simplified
135
136	!> @todo Many statement comments that are given as doxygen comments need to be changed to normal comments
137	!> @todo Replace window_area_per_facade by %frac(1,m) for window
138	!> @todo emissivity change for window blinds if solar_protection_on=1
139
140	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
141	!> @note How to write indoor temperature output to pt array?
142	!>
143	!> @bug <Enter known bugs here>
