The systems approach is claimed not to fit with the market reality. If the common benchmark approach is implemented, it will lead to market distortions and to the discrimination of certain heating systems technologies. In particular, it will lead to a discrimination in favor of packaged systems and against ad-hoc installed systems, which are claimed to be the most commonly
installed in certain member states.

...a risk is perceived that the common benchmark approach could lead to market distortions and the discrimination in favor of
commercially available packaged systems vs. ad-hoc installed systems (not available off-theshelf).

Zřejmě standardní (hotové? unifikované?) řešení vs ad hoc systém, ale nevím jak to přesně postihnout.
