CombiSound – Combined renovation for sound insulation and comfort in residential buildingsCombiSound – Combined renovation for sound insulation and

Project

When deciding to replace older apartment blocks, a lack of sound insulation between residential apartments is often an important argument. Renovations that improve sound insulation in the building may reduce the need for building replacements. Synergies can be utilised with the simultaneous introduction of surface heating systems, that pay off… ...

AsphaltReg – Demonstration and optimization of a recyclable asphalt collector for the regeneration of geothermal probesAsphaltReg – Demonstration and optimization of a recyclable

Project

This project is the first to build, measure and optimise a recyclable asphalt collector for the regeneration of geothermal probes.
The background to this pilot and demonstration project is the increasingly dense use of geothermal probes, which leads to long-term cooling of the subsoil. Studies show that there is a considerable need for… ...

PLURAL – Plug-and-Use renovation of facades with adaptable lightweight systemsPLURAL – Plug-and-Use renovation of facades with adaptable

Project

Reducing heat losses from existing residential buildings by refurbishing the building envelope is an important step to reduce the heating demand of buildings. In the EU project PLURAL, prefabricated façade modules are being developed and tested, which enable novel possibilities for energy generation, heat/cold supply and ventilation with the… ...

OblaTherm – PVT and foundation slab as a heat source and sinkOblaTherm – PVT and foundation slab as a heat source and

Project

For the new building of Oblamatik AG in Chur, a heating and cooling concept that is unique in Switzerland was developed. Using the foundation slab as a heat sink and heat source represents an alternative to the current heating systems for office buildings. The regeneration of the foundation slab in winter as well as in summer is mainly guaranteed… ...
