ReWAX – Smaller heat pump dimensioning by X-to-Energy for peak load coverageReWAX – Smaller heat pump dimensioning by X-to-Energy for

Project

By using a peak load auxiliary heating system, oversizing of the heat pump can be avoided. Oil and gas peak load boilers are standard today but should be replaced in the future due to their CO2 emissions and measures to fight climate change. The utilization of biomass as an energy source is comparatively more complex and domestic biomass resources… ...

GISOptiTes - Potential assessment of large-scale seasonal thermal energy storage in Switzerland by means of GIS based energy modelling and optimizationGISOptiTes - Potential assessment of large-scale seasonal

Project

In this project we will develop a methodology to increase the synergies between top-down and bottom-up energy optimization tools with the aim of assessing the potentials of large-scale seasonal thermal energy storage (TES) in Switzerland.
The top-down approach carried out with Energy Scope will be used to assess the transition path and the… ...

PeakMetal – Covering winter peaks of heat and electricity demand by «renewable metal fuels»PeakMetal – Covering winter peaks of heat and electricity

Project

Renewable Metal Fuels (ReMeF) are seasonal energy carriers which are able to enhance the energy security. We investigate the contribution that ReMeF can make as combined heat and power elements of the building stock a) to cover the local demand for electricity and heat and b) to feed electricity into the grid to support the energy system. In focus… ...

OptiPower - Investigating the optimal design of the power of heating and cooling systems for residential and administrative buildingsOptiPower - Investigating the optimal design of the power of

Project

Experience from various pilot and demonstration projects, as well as the assessment of experts, suggests that heating and cooling systems are often oversized. However, since there were no systematic studies on this topic in Switzerland, the Swiss Federal Office of Energy (SFOE) commissioned the SPF and the IET - Institute of Energy Technology with… ...

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… ...
