Last change on this file since 4781 was 4780, checked in by suehring, 4 years ago
Urban-surface model and indoor model: Default building parameters updated and extended; revision of summer- and wintertime-dependent indoor parameters (responsible S. Rissmann); extension of albedo parameters to different building facades and roofs; first and second wall layer initialized with individual building properties rather than with with the same properties (heat capacity and conductivity)

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

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
