BERS Pro v4.3 Modelling Restriction
BERS Pro v4.3.0.X (3.13) cannot be used to model 'roof windows'. Roof windows are 'openable or fixed windows in a roof' and do not have a shaft, as distinct from skylights which incorporate a built-in shaft and are not ventilated.
BERS Pro v4.3.0.X (3.13) can only model skylights.
Please check the documentation provided that no ‘roof windows’ have been included in the house design.
