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