Last change on this file since 4760 was 4750, checked in by suehring, 4 years ago
Indoor-model new: Namelist parameter added to switch-off/on the indoor model during wall/soil spinup; bugfixes concerning indoor model: bugfix in window-wall treatment during spinup - in the urban-surface model the window fraction is set to zero during spinup, so it is done here also; bugfix in wall treatment - inner wall temperature was too low due to wrong weighting of wall/green/window fractions; Revision of 10-cm temperature at vertical walls - assume grid-cell temperature rather than employ MOST; call hourly-based indoor model only once per hour during spinup, not every timestep; add missing dependency in Makefile; urban-surface model: bugfix in openmp directive

[4750]	27	! - Namelist parameter added to switch-off/on the indoor model during wall/soil spinup
	28	! - Bugfix in window-wall treatment during spinup - in the urban-surface model the window fraction
	29	! is set to zero during spinup, so it is done here also
	30	! - Bugfix in wall treatment - inner wall temperature was too low due to wrong weighting of
	31	! wall/green/window fractions

	166	!> Module for Indoor Climate Model (ICM)
	167	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
	168	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
[4646]	169	!> This module differs between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine
	170	!> thermal comfort
	171	!> the heat transfer between indoor and outdoor is simplified
[4246]	172
[4646]	173	!> @todo Many statement comments that are given as doxygen comments need to be changed to normal comments
[4246]	174	!> @todo Replace window_area_per_facade by %frac(1,m) for window
[4646]	175	!> @todo emissivity change for window blinds if solar_protection_on=1
[4246]	176
	177	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
	178	!> @note How to write indoor temperature output to pt array?
	179	!>
[4687]	180	!> @bug Calculation of iwghf_eb and iwghf_eb_window is faulty
