[4402]	32	! Major bugfix in calculation of energy demand - floor-area-per-facade was wrongly
	33	! calculated leading to unrealistically high energy demands and thus to
	34	! unreallistically high waste-heat fluxes.

	126	! ------------
	127	!> <Description of the new module>
	128	!> Module for Indoor Climate Model (ICM)
	129	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
	130	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
	131	!> This module differ between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine thermal comfort
	132	!> the heat transfer between indoor and outdoor is simplified
	133
	134	!> @todo Replace window_area_per_facade by %frac(1,m) for window
	135	!> @todo emissivity change for window blinds if solar_protection_on=1
	136
	137	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
	138	!> @note How to write indoor temperature output to pt array?
	139	!>
	140	!> @bug <Enter known bugs here>
