Guidelines on energy consumption labeling

Regulations (EU) No. 1253/2014 and (EU) No. 1254/2014 stipulate an energy efficiency classification for some ventilation appliances. They range from A+ (top rating) to G and can be easily read off using an energy label.

LUNOS guarantees compliance with all product declaration regulations. Ventilation units that require labeling include all products with heat recovery and those units with a maximum power consumption of more than 30 watts.

The Silvento ec from LUNOS is so efficient that its maximum power consumption is 14.5 watts. It therefore does not fall under this requirement and is therefore expressly not allowed to be labeled.

Display units

The retrospective label obligation also applies to display appliances. This means that from 01.01.2016, the label must also be retrofitted to display appliances that have already been installed. If you are exhibiting the above-mentioned LUNOS appliances and still require a label, please contact


The Energy Labelling Directive 2010/30/EU, which was adopted in 2010 and replaced the old EU Framework Directive 92/75/EEC, is intended to make an important contribution to increasing energy efficiency in Europe. On this basis, regulations are issued for selected product groups that contain detailed, product group-specific requirements and information on labeling. The regulations apply directly in all EU member states.

Regulation (EU) No. 1253/2014 and (EU) No. 1254/2014 apply to LUNOS ventilation units. This EU regulation on the minimum efficiency of ventilation systems came into force on November 26, 2014. It was created in the context of a large number of other ecodesign directives that regulate the minimum energy efficiency of products. Planners and system manufacturers should be familiar with the regulation, as it has a major influence on the technical design of ventilation units.
