Verified energy efficiency

In anticipation of the European directive on eco-design requirements for energy-using products (Eco-Design Directive), the European manufacturers’ association EUROVENT and the German association of AHU manufacturers have established methods for the energetic assessment of central air handling units. Decisive factors for efficiency are the fan/motor combination, the air velocity inside the unit and the heat recovery unit.
Both methods aim at transparency of classification. Energy efficiency labels on the central air handling units inform planners, installers, investors and users about the class achieved.
Manufacturers applying the method must undergo a strict certification procedure and yearly inspections by the Technical Inspection Agency (TÜV). The test method is supplemented by measurements taken on actual units and the tracing to already certified components. This ensures that the data supplied by the design software of the participating manufacturers will be correct.

EUROVENT energy efficiency classes

The European EUROVENT method allows classification into six classes from A+ to E. The assessment method is based on the standard DIN EN 13053.
By means of a compensation method, the use of thermal and electrical energy is assessed on the basis of the primary-energy demand.

Energy efficiency classes according to the German association of AHU manufacturers

The method of the German AHU manufacturers' association relies on three classes A+, A and B. The assessment method is based on the standard DIN EN 13053 and on the AHU Guideline 01 of the German manufacturers’ association.
The energy efficiency classes according to the manufacturers’ association allow simple, traceable and verifiable assessment of the factors influencing energy efficiency.
