Analysis of additional costs in the European construction sector caused by faults having occurred during the construction process identified nearly 10% of the turnover of the construction sector. Thus, quality of works is not only crucial for achieving EU energy and climate goals but also essential from the economic point of view.
Point of departure: what is the importance of quality of the works?
New buildings as well as the existing building stock must become much more energy efficient to achieve the EU energy and climate goals envisaged for the years 2020, 2030 and beyond. In fact, it will be possible to almost completely cut emissions from residential and office buildings by around 90% in 2050, compared to 1990, if all efforts undertaken are successful. These efforts include quality of the works, meaning that it is not sufficient aiming at an excellent energy performance stated by design descriptions and energy calculations, but also at good quality of the works. Proper execution of building works according to plan and without errors is the precondition to achieve high building energy performance in reality, resulting in actual reductions in energy consumption and emissions. In this regard, experience shows that there are various cases where the quality of the works is an issue of concern, sometimes even causing major difficulties leading to higher expenses.
