First, varying the classification from member state to member state would be a significant limitation on the label. Using the common A to G level, of course, it is easier to reach the A level in warmer climates, but at the same time the energy saving potential is lower. This means for example that a lower insulation level is sufficient in Portugal to reach class A which is very well in line with the economic optimisation: as a higher insulation thickness would not be economic if the heating load is low. The Display™ classification is very close to the Danish classification scheme, the only one existing in Europe so far.
Second, member states will have to develop their own implementation scheme for the EBPD by the end of 2005, so probably they will introduce different classification schemes. In this case it is easier to replace the Display™ classification on the Display™ poster by the national classification scheme than to replace in two years time a national classification scheme developed under Display™ by the one prepared by the member state itself.
In addition, during the pilot phase of the Display™ Campaign until June 2005, it is possible to enter modifications in the classification scheme. All participants will be informed in advance about modifications that have been arranged with the Display™ working group via the Display™ eGroup.
