The Eco-Design Directive ErP. The Newest Requirements. Tightened Requirements of the EC-Regulation 1253/2014/EG are forcing designers and manufacturers of AHUs to adapt previous solutions.
The Eco-Design Directive ErP. The European ErP-Directive 2009/125/EG (Energy-related-Products-Directive), also called the Eco-Design Directive, defines the minimal requirements for energy-related products. The objective of the ErP-Directive is the reduction of energy consumption and the CO 2 -emission rates as well as an increase of the overall share of renewable energies. This directive applies for all products placed on the market within the European Economic Area (EEA). Exports from the European Community (EC) are not affected by the ErP-Directive. Relevant for the AHUs is the EC-Directive 1253/2014/EG that came into force on November 26th 2014. Within the framework of this directive and as of January 1st 2016, new requirements concerning the energy efficiency of AHUs will apply within the European Economic Area (EEA).

The Consequences of the ErP-Directive The tightened requirements of the ErP-Directive have far-reaching consequences for both AHUmanufacturers and designers. This is clearly illustrated by the following example. Under the same general conditions for example, an AHU that was designed for 2015 looks completely different than a solution that complies to the ErP-Stage 2016 or even the ErP-Stage 2018. General Conditions Combined supply and exhaust air unit Air flow volume: 10,000 m³/h (Supply Air) / Air flow volume: 10,000 m³/h (Exhaust Air) Filters F7 (ODA), Filters M5 (ETA) HRS-System: Run-around coils system Additional Components: 1 air-heater and 1 damper in the supply air, 1 damper in the exhaust air EC-Fans Air Conditions (DIN EN 308) Outdoor Air: 5 C, 0% relative humidity Exhaust Air: 25 C, 0% relative humidity AHUs according to the stand of 2015 Abbreviations for types of air (as specified in DIN EN 13779): ODA = outdoor air, SUP = supply air, ETA = extract air, EHA = exhaust air robatherm 04/2016 Page 4

Comparison of the Three Unit Concepts These specific figures only refer to the designated example. However, during the course of the ErP- Directive, it can be presumed that the space required for AHUs in the future shall increase due to larger dimensions. An increase of investment costs can be anticipated, which to a large extent shall be based on the increased HRS-Systems requirements.
