Attic spaces intended for departure may only be regarded as departure if they are accessible via a fixed staircase and if the floor is passable and the roof is boarded.
2. Surface area of ​​other spaces
The rooms are only valued as 'other surface' if the floor is passable.If it concerns an attic, the additional condition is that the roof is boarded and that the attic space is accessible via a staircase belonging to the house. If these conditions are not met, those spaces will not be included in the home valuation.
Inputs needed:

The points from this rule are depicted from the heating rooms. Open kitchens, or rooms that are connected by a sliding wall, are counted as separate rooms. The rooms are considered as heated rooms if the heating is part of the immovable property and its appurtenances. The other rooms are the rooms that are not considered to be heated.
Inputs needed:

4. Energy label in combination with the area of the home and the housetype
The rental committee may deviate from the indicated point rating for the energy performance associated with a better energy label class than A. Such a deviation is only possible if the costs incurred to achieve this energy performance deviate significantly from what is considered normal, or if the energy performance is significantly better than what is considered common for an energy label class A.
Where a valid energy label is lacking, it is sufficient to evaluate the minimum energy performance that a home is expected to achieve on the basis of the building standards in force in the year of construction. As a result, the absence of an energy label leads to a lower number of points than if an energy label has been provided. After all, valuing the energy performance based on the year of construction of the home does not take into account the fact that the energy performance of many homes improves over time by implementing energy-saving facilities. These improvements are reflected in an energy label.

energy_label_available
energy_label
house_type
building_year
energy_performance_payment
