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.
