The Chamber of Craft Trades of Münster modernized this old (1913) villa in Gelsenkirchen's Buer district as a "Building Modernization Demonstration Center" in order to illustrate energy-saving technologies applied to existing buildings to craftsmen, architects and engineers, and also to specialized lawyers and building-industry clients. The center makes it possible to demonstrate various energy-efficient designs for walls, ceilings, roofs and ventilation systems.
