EUROVENT
In addition to the unambiguous classification of the energy consumption you can expect from your chosen unit, certification offers other substantial advantages that are worth real money. ■ The classification of equipment into energy efficiency classes is an essential feature of the certification. You receive a unique classification of the energy consumption you can expect with the selected unit. This allows the operating costs to be identified uniquely.
■ The independently measured and verified information gives you security for your configuration. You can gear the configuration precisely to the operating point – safety margins aren’t necessary.
■ Having certified data makes it easier to compare different units. This ensures fair competition under realistic conditions.
■ The ‘certify-all principle’ ensures that manufacturers cannot make their name with a few top seller units – it is always complete series that are certified, so there are no loopholes for individual units.
■ The confirmed and hence reliable technical
Energy classes thresholds.
data increases investment security and guarantees safe and reliable planning and operation in relation to the performance and energy efficiency of the complete system. The operating costs are clearly calculable from the outset.
■ Certified units save real money: “We recommend every user with a current or upcoming construction project to calculate the energy consumption resulting from a hypothetical inaccuracy. Serial testing performed a couple of years ago highlighted an inaccuracy of up to 35% with non-certified units. A reduced performance of 15 to 20% could therefore realistically be assumed for
calculation purposes. A much better payback period can be identified in the case of certified units on the other hand, generally less than two years.
■ Eurovent certification of the selected units is an essential prerequisite to obtain grants from certain funding programmes throughout Europe.
