SKINNSKATTEBERG, Sweden, 7 May 2021: Eurovent Certification is set to launch the Energy Efficiency Classes for Summer Application (EECS) label for air handling units (AHUs), which includes cooling and accommodates warmer weather conditions. The label will be made mandatory from September 2021. Systemair is fully prepared to provide the summer label for its entire range of Eurovent-certified AHUs. Customers will be given the option to print the extra label through the online selection tools by June.

Jörn Doerk, Technical Product Manager, AHU Design and Certification, Menerga, Systemair Group, provides a background on the development of the summer label: “Over the years, the Eurovent Certification energy label for AHUs has become a trusted reference point for the market through its easy rating scheme. This has helped customers effortlessly compare various brands in the market and ensures simple conditions can be set for the selection of an AHU. However, it is important to build awareness on the importance of looking at the performance of units in warm climates as currently all labels are working according to winter conditions. This is because many initiatives were largely driven by colder countries in Northern Europe, which were the first ones to highlight the need to look at opportunities for energy savings. It was dismissive of the situation in areas with warmer climates and that is what we want to change and correct with the introduction of the summer label.”

Andy Bijmans

Weighing in, Andy Bijmans, Manager Development, Systemair, The Netherlands, says, “The Eurovent summer label wants to strengthen the idea of energy saving in the context of hot weather situations. As such, it has the added benefit of acknowledging humidity recovery in view of its important contribution to overall energy efficiency performance, which makes the label more advanced than the calculations for the winter label. The new label gives a realistic representation of the usefulness and necessity of a certain heat recovery efficiency in summer conditions, with the air resistance that this may cost at a certain fan efficiency. Meeting the summer label requirements also showcases the superior performance of Systemair AHUs as our various ranges can address the demands of customers in all regions and reflects our move to push energy efficiency.”

The Eurovent Certification summer label utilises ASHRAE climate database to obtain realistic climate conditions. This ensures customers can get the most accurate energy calculation and assessment. Customers can select their location or the closest fixed city available to get the suitable options in the AHU configurators of Systemair and Menerga. The calculations have considered the temperature and humidity at the highest level, in view of its impact on the cooling rate.

Systemair has played an active role in initiating discussions surrounding the summer label through representatives in the Eurovent Association board, and this milestone reflects Systemair’s position as a global supplier committed to ensuring all markets can choose the most energy efficient solutions according to the appropriate technical requirements.
