	84	! ------------
	85	!> <Description of the new module>
	86	!> Module for Indoor Climate Model (ICM)
	87	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
	88	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
	89	!> This module differ between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine thermal comfort
	90	!> the heat transfer between indoor and outdoor is simplified
	91
	92	!> @todo Replace window_area_per_facade by %frac(1,m) for window
	93	!> @todo emissivity change for window blinds if solar_protection_on=1
[4148]	94
[3744]	95	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
	96	!> @note How to write indoor temperature output to pt array?
	97	!>
	98	!> @bug <Enter known bugs here>
