“More interior work, less shell construction“

The proportion of building construction costs that falls on interior work like thermal insulation in houses is rising in Germany, Bernd Freytag writes in Frankfurter Allgemeine Zeitung. Depending on the definition, thermal insulation in line with the latest energy saving regulations makes up between seven and ten percent or even more of total construction costs, Freytag explains. “Especially installers of heating systems have substantially expanded their share from 3.7 percent to 6.4 percent,” he says. According to industry lobby groups, Germany’s new Energy Saving Ordinance (EnEV) is the main reason for the cost increase, Freytag adds.
