Domhöfe Wetzlar
Location Domplatz 12 in Wetzlar
The Domhöfe Wetzlar are a new building project in the immediate vicinity of Wetzlar Cathedral .
Three courtyards, each separated by an alleyway, will be built on a two-storey underground car park.
In the first, northern courtyard (Herzoglicher Hof), there will be a mix of uses consisting of restaurants on the first floor, offices/practices on the second floor and apartments above.
The middle courtyard houses premises for a variety of cultural and leisure uses. There is a science center and tourist information on the first floor. The cinema hall can also be used for theater and concerts. The upper floors above the science center can be used flexibly for commercial, artistic or residential purposes.
The third, southern cathedral courtyard is to be used largely for apartments. The inner courtyard will be accessible to all.
The project is aiming for DGNB "Sustainable Building Site" certification from the German Sustainable Building Council.

Certified by the German Sustainable Building Council (DGNB)
Ed. Züblin AG is pursuing several goals with this project: A sustainable construction site organisation, the conservation of resources as well as the minimisation of emissions, responsibility for the health and well-being of the builders, the cultivation of good neighbourliness and, of course, high-quality construction. For this, Ed. Züblin AG was the first company to be recognised by the German Sustainable Building Council (DGNB).

Selected measures in the project
-
Finished parts
The extensive use of precast elements (cavity walls, filigree slabs, stairs, balconies, connecting walkways, steel composite beams and prestressed concrete hollow core slabs) means that a shorter construction time can be achieved. In addition, the precast elements are dimensioned in such a way that no additional lifting equipment is required and the existing construction site cranes are adequate. The reduction in construction time due to the high use of precast elements on the construction project results in the minimization of noise and dust emissions from the construction site, as additional work on site is no longer required. At the same time, the volume of waste is reduced.
-
Saving resources with system formwork
The DokaXdek slab formwork system is used on the construction site. This enables faster shuttering and striking, which leads to a reduction in construction time. Compared to conventional timber girder formwork, material consumption, scrap and losses are also lower. For areas where conventional shuttering is required, wooden beams and formwork facing are used from material stocks from completed construction projects.
-
Measures to prevent pollution from the construction site
The project is in an inner-city location, so the impact of the construction site is reduced as much as possible. By using concrete pumps, larger concreting sections can be realized in a shorter time than in the conventional way with concrete buckets. Noise emissions caused by the use of concrete vibrators are limited to a shorter period of time. The high proportion of prefabricated components also reduces noise pollution from the construction site to a minimum.
-
Crane rope made from carbon fibers
Fiber ropes are lighter than conventional steel ropes. This reduces the energy requirement while increasing the load capacity of the cranes by up to 20 percent. Further advantages of using carbon fiber crane ropes are the increased material service life and the reduction in noise emissions during crane operation. Overall, this leads to an acceleration of the construction site process and a reduction in noise pollution from the construction site.
-
Energy management in construction and cooperation with regional companies
Lights with motion sensors are installed in passageways and corridors in the day accommodation. The main suppliers of building materials and concrete are located within a radius of 10 km from the construction site.
-
Mindful material handling and material retrieval
Material call-offs are timed so that waiting times for delivery vehicles are eliminated or, if not otherwise possible, are kept to a minimum. In addition, the call-offs are dimensioned in such a way that the transports are as fully loaded as possible. Residual quantities of in-situ concrete are used for the clean layer.
