32	! 4441 2020-03-04 19:20:35Z suehring
33	! Major bugfix in calculation of energy demand - floor-area-per-facade was wrongly calculated
34	! leading to unrealistically high energy demands and thus to unreallistically high waste-heat
35	! fluxes.

44	! 4310 2019-11-26 19:01:28Z suehring
45	! Remove dt_indoor from namelist input. The indoor model is an hourly-based model, calling it
46	! more/less often lead to inaccurate results.
47	!
48	! 4299 2019-11-22 10:13:38Z suehring

80	! Bugfix in case of non grid-resolved buildings. Further, vertical grid spacing is now considered at
81	! the correct level.
82	! - change calculation of a_m and c_m
83	! - change calculation of u-values (use h_es in building array)

124	! Description:
125	! ------------
126	!> Module for Indoor Climate Model (ICM)
127	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
128	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
129	!> This module differs between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine
130	!> thermal comfort
131	!> the heat transfer between indoor and outdoor is simplified
132
133	!> @todo Many statement comments that are given as doxygen comments need to be changed to normal comments
134	!> @todo Replace window_area_per_facade by %frac(1,m) for window
135	!> @todo emissivity change for window blinds if solar_protection_on=1
136
137	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
138	!> @note How to write indoor temperature output to pt array?
139	!>
140	!> @bug <Enter known bugs here>
