Especially work on existing building substance is handled and influenced differently, as the current B+L Renovation Study shows. Study author Marcel Dresse says: "In the international comparison, significant differences were found not only in terms of the renovator's social demographics but also with regards to product preferences and renovated building sectors. "In Germany and Great Britain, also older generations increasingly get into renovation while in France, renovators on average are considerably younger."
These difference were also reflected in the income level and the chosen renovation measures. Younger renovators, for instance, focus more on attics than older generations. Measures that amortize only over many years are rather used by younger age groups. Looking at capacity bottlenecks, Dresse identified the following problem: "In France and Germany the share of renovators who take care of renovation measures themselves is considerably higher than in Great Britain. At the same time we observed that the higher the age of the renovator, the more importance professionals gain in many renovation sectors."
