	71	!> <Description of the new module>
	72	!> Module for Indoor Climate Model (ICM)
	73	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
	74	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
	75	!> This module differ between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine thermal comfort
	76	!> the heat transfer between indoor and outdoor is simplified
	77
	78	!> @todo Replace window_area_per_facade by %frac(1,m) for window
	79	!> @todo emissivity change for window blinds if solar_protection_on=1
	80	!> @todo write datas in netcdf file as output data
	81	!> @todo reduce the building volume with netto ground surface to take respect costruction areas like walls and ceilings. Have effect on factor_a, factor_c, airchange and lambda_at
	82	!>
	83	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
	84	!> @note How to write indoor temperature output to pt array?
	85	!>
	86	!> @bug <Enter known bugs here>
