Energy Efficiency

Energy saving and energy efficiency are becoming increasingly important as a result of rising energy costs and calls from central government for the reduction of CO2 emissions. There is considerable scope for meeting energy-saving goals within the area of refrigeration, air conditioning and ventilation technology, and also in building services engineering.

Transposition of the Energy Performance of Buildings Directive 2002/91/EC (known as the EPBD) into national law led in Germany to the Federal Energy Saving Act (Energieeinspargesetz - EnEG) and the Energy Saving Ordinance ( Energieeinsparverordnung - EnEV) based upon it, along with the more stringent new version of 2009.

These ordinances stipulate that the energy requirements of plant and equipment have to be documented. In the case of ventilation and air conditioning equipment, efficient operation particularly depends on efficient transportation of air (Specific Fan Power or SFP value) as well as on the efficiency of heat recovery (heat recovery rate η).

In the case of climate control equipment which uses coolants for heat transference, the emphasis is on the Coefficient of Performance (COP) and the Energy Efficiency Ratio (EER). These values indicate how much thermal energy results from the use of electrical energy.

An examination of the performance capability and energy efficiency of air conditioning equipment and components by the inspection body for refrigeration, air conditioning and ventilation technology at TÜV NORD can lead to a considerable competitive advantage in comparison with other manufacturers. Following a successful inspection, the resulting certificate and TÜV NORD test mark can be used for marketing purposes. The findings of the third-party inspection also offer engineers, planning architects and plant operators an assurance that they can rely on the performance data supplied by the equipment manufacturers.

Independent Test Laboratory

As an approved and independent test laboratory we offer a wide range of testing for refrigeration, air conditioning and ventilation plant and equipment based on national and international standards and directives. The test laboratory works in accordance with the basic principles of ISO/IEC 17025.

In addition, the certification body has worked for the EUROVENT Certification Company SCRL, a European manufacturers' federation located in Paris, for more than 15 years. Central air conditioning units, rooftop units and comfort and precision air conditioning equipment are tested on behalf of this organisation. By commissioning us, EUROVENT is demonstrating its confidence in the technical expertise and years of experience of the TÜV NORD inspection body.
