GreatSolarThermalFields

Project

The project supports the development of reliable large-scale solar thermal fields in Switzerland through a practical, hands-on toolkit, including guidelines and the development of a Python-based backend for the calculation and design of solar fields. It is carried out in collaboration with AEE INTEC, combining the expertise of experienced national… ...

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… ...

StoWaDim-WRG – Efficiency and Storage Sizing with Shower Water Heat RecoveryStoWaDim-WRG – Efficiency and Storage Sizing with Shower

Project

In modern, well-insulated buildings, the relative share of hot water demand in total heat demand is steadily increasing. Since showering significantly determines hot water demand and daily hot water peaks, heat recovery from shower wastewater offers considerable potential for increasing energy efficiency. Furthermore, depending on the installation… ...

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… ...

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… ...
