Vibration isolation and structure-borne sound control in Hohenlind
The Hohenlind neighbourhood in the Hohenlind district of Cologne has created a modern, urban residential and living environment that meets high standards of sustainability, comfort and technical infrastructure. As part of the neighbourhood’s development, a central energy supply system was implemented to provide the entire site with an efficient and future-proof energy supply. A key component of this concept is a high-performance, underground energy centre, which was already implemented during the first construction phase.
At the heart of this energy centre is a combined heat and power (CHP) plant covering an area of around 160 m². Due to its immediate proximity to residential buildings and neighbouring structures – in particular an underground car park – protection against vibrations and structure-borne noise presented a key planning challenge. The aim was to reliably decouple the operation of the technical plant and permanently prevent disruptive effects on the surrounding area.
Project overview
Vertical decoupling of the side walls
REGUPOL vibration 450 was used to address this challenge. The material was specifically employed to provide vertical decoupling of the side walls and to isolate the energy centre from the adjacent underground car park. This structural measure effectively reduced vibration transmission and ensured a high level of sound insulation for the surrounding areas.
In addition, the energy centre was fitted with a chimney approximately 30 metres high, consisting of 23 prefabricated elements and separated from the existing building by a joint approximately 10 centimetres wide. This structural separation supports the overall decoupling concept and further helps to minimise the impact of emissions on the surrounding buildings.
The use of REGUPOL vibration 450 in the Hohenlind neighbourhood has delivered a high-performance and sustainable solution for vibration isolation that meets the high standards required of modern neighbourhood developments in inner-city locations.
