Which products are affected by Ecodesign ?
The European Union has developed two directives ( Ecodesign Directive 2009 / 125 / EC and Energy Labeling Directive 2010 / 30 / EC ) to address the environmental impact of all Energy related Products ( ErP ) beginning at the earliest stages of design . The Ecodesign directive affects all types of Energy related Products ( ErP ) such as TVs , washing machines , lights and , of course , also HVAC products and components . Energy related Products ( ErP ) are grouped into “ Lots ” that , once they are published , they become mandatory CE regulations . There are three Ecodesign Lots ( already approved regulations ) that directly impact HVAC products .
¢ ENER Lot 21 ð Reg 2016 / 2281 ð Central Heating and Cooling Products ( Chillers ) ¢ ENTR Lot 1 ð Reg 1095 / 2015 ð Professional Refrigeration ( Process Chillers Brine ) ¢ ENER Lot 1 ð Reg 813 / 2013 ð Space Heaters ( Heat Pumps )
Each of the three regulations set the MEPS or Minimum Efficiency Performance Standards for the product category and those are implemented in 2 steps ( Tiers ), as shown in the table below .

Ecodesign has changed the way we speak
Former full efficiency ratios like EER and COP are now disappearing . Even the seasonal efficiency ratio ESEER has been replaced . Ecodesign MEPS are the current key indicators used for all HVAC product and compliance is mandatory to have the CE marking . The Eurovent organization is already using Ecodesign MEPS at the different certification programs are not using ESEER value anymore .

Calculation method An important point that must be specified on the manufacturers rating report is the calculation method regarding the water flow and outlet temperature . According regulation there are four possible methods .
FW / FO = Fixed Water Flow , Fixed Outlet Temperature FW / VO = Fixed Water Flow , Variable Outlet Temperature
VW / FO = Variable Water Flow , Fixed Outlet Temperature VW / VO = Variable Water Flow , Variable Outlet Temperature
• Variable Outlet allows to change the leaving water temperature at partial load . This reduces the lift required by the chiller , reducing energy use significantly . To provide this rating , chillers must be capable of automatic water temperature reset based on outdoor ambient temperature . With this capability , even projects without advanced building control systems can benefit .
• Variable Flow reduces energy use at part load through reduced waterside pressure drop . Variable Speed Pumps must be fitted to the system to benefit from this savings .
• It is important to note that efficiencies can vary hugely depending on the temperatures and the method of calculation .
• It is crucial to check the chilled water conditions used to determine the SEER , SEPR and SCOP when comparing the seasonal energy efficiency .
