Historically, that is to say for the past 30 to 40 years, the benchmark for quality in the systematic assessment of buildings has often been considered to be energy efficiency. Recent years have seen a growing prevalence of building and sustainability assessment systems that, as well as an already comprehensive ecological assessment, also look at broader aspects of assessing housing quality. This means that societal, social, local and other aspects of sustainability are incorporated into the building assessment. In Luxembourg, a certification system was developed, based on existing systems, which is specifically fine-tuned to the needs of residential properties (both houses and flats).

Comprehensive quality assurance during construction is a key factor in professionally implementing a design. There is a whole series of certification systems that enable firms to organise, monitor and improve their processes and the quality of the work they deliver. Most of these systems also include environmental aspects. By selecting certified firms, the quality of construction can be increased.

By choosing certified SuperDrecksKëscht® fir Betriber firms, the construction can be awarded up to 5 points under the LENOZ certification. (Points 5.5.2, 5.5.4, 5.5.6, 5.5.8, 5.5.10 of the LENOZ Handbook, Version 53 dated 12 December 2016).

In addition, up to 2 further points can also be awarded when a comprehensive construction site waste concept complies with SDK rules. (Point 5.5.11 of the LENOZ Handbook, Version 53 dated 12 December 2016).

Separated waste collection, corresponding waste transportation, waste prevention, disposal and providing evidence are the main inspection points for labelling the construction site under the SDK concept.
