In 2010 the city of Worms developed a climate protection and energy efficiency concept to reduce CO2 emissions in cooperation with the Climate Alliance, a European network of cities, communities and administrative districts.

One part of this concept focuses on the renovation of old buildings.

With this in mind, the company Wohnungsbau GmbH Worms established the network “Cluster Initiative Worms” at the end of 2010.

Thanks to highly insulating building materials, an intelligent heating system in conjunction with heat pump technology and solar thermal energy, as well as a controlled ventilation system with heat recovery, considerable improvements in the energy balance of the building are expected.

Another important aim of this trailblazing project is to adopt the positive know-how acquired through modernisation for future measures.

With the Baumit lime plasters Kalkin KP 36 W and Kalkin smooth W, an interior plaster system that regulates moisture was chosen, thus improving the climate of the rooms, and that absorbs and breaks down contaminants such as carbon dioxide (CO2) and sulphur dioxide (SO2) like a catalyst.

Baumit super insulation façade, a thermal insulation system which deploys adhesive anchors to avoid thermal bridges and dowel marks, was used to insulate the façades and is achieved using permeable EPS insulation board. Baumit Nanopor Top is used for the final coat.

Special attention was been paid to the colour scheme of the renovated property.

With the warm grey and sandstone tones created in Daniela Vomfell’s colour concept, the design of building reflects the old city walls of Worms.

The horizontal pale stripes subdivide the building’s cube shape, creating a pleasant lightness in conjunction with the similarly bright loft extension; while the warm sections between the windows, reminiscent of the sandstone tones of the city walls, ensure a friendly and welcoming colour scheme.
