The prize for sustainability was awarded for the first time in 2015 in the open category for the "energy-efficient hall construction system for wineries" of the Altez Group in Tielt (Belgium).
The excellent product is large maintenance-free concrete wall elements with internal thermal insulation, which due to the high storage mass make additional energy costs for heating or cooling the halls unnecessary. The concrete wall elements retain their hard surface and are weather-resistant for many years. The jury was impressed by the sustainable passive construction in the area of production halls, which is made possible by the highly insulating concrete wall elements and saves additional energy expenditure. The environmentally friendly production process was also considered positive, where not only water is saved, but the required energy comes from the company's own photovoltaic systems and the wood used for formwork is used to heat the production halls.
